The Dark Side Of CFLs

E-mail Print

Consider this - instead of saving the environment, CFLs are actually destroying it. CFLs should be thought of as toxic technology, when mercury contamination, ultraviolet radiation, and radio frequency radiation are factored in. From cradle to grave, CFLs pose a danger to people’s health and well being, as well as adding even more toxicity to the environment. In fact, CFLs do not reduce a person’s carbon footprint and may even increase it in some situations. To make matters even worse, CFLs emit harmful levels of electromagnetic radiation.

Starting in the year 2012, regular incandescent bulbs, the ones invented by Thomas Edison over 100 years ago, will be banned in Canada in the pursuit of reducing greenhouse gas (GHG) emissions. Yet, contrary to popular belief, switching from regular bulbs to CFLs could increase global energy consumption, not reduce it. If that alone does not shake consumer confidence, perhaps the facts that CFLs contain mercury and also emit electromagnetic radiation might give people a wake-up call up to the truth about CFLs.

On the other hand, since CFL producers are being handed a monopoly in the light bulb market by some federal government and are being cheered on by corporatist environmental groups, sales are not about to drop anytime soon.

It seems like the protectors of the environment have jumped ship. Health Canada is simply not doing its job as they ignore the devastating impact of having millions of CFLs in our environment. Why are they sitting by, and allowing the Canadian government to force its citizens to use them?

To make matters even worse, groups such as the Suzuki Foundation and Greenpeace, whom Canadians have come to rely on to protect them from environmental pollutants, have chosen to ignore the potential looming environmental and health risks, and blindly promote the use of CFLs.

Why have environmentalists and the government joined in an alliance with the electrical industry in promoting an undeniably dangerous product? Whose side are they on anyway?

Canadian Health and Safety officials seem to be asleep at the switch, oblivious of the hazards, and environmentalists appear to have sold out, as manufacturers and sellers of CFLs are laughing all the way to the bank.  With impunity “los tres amigos”, the manufacturers, the corporatist environmentalist backers and government, are leaving misled consumers to deal with the aftermath of a potential environmental catastrophe.

Meanwhile, the New Zealand government, citing concerns about CFLs lack of efficiency and safety, has lifted its ban on incandescent bulbs.  Hopefully other governments will see the wisdom in this decision and follow suit.

Corporatist Environmentalists

Corporatism is the dominant ideology in today’s western democracies. “While the corporatist society maintains a veneer of open criticism and democracy, it squelches opposition to dominant corporate interests by using propaganda and rhetoric to obscure facts and to deter communication among citizens. Corporatism creates conformists who behave like cogs in organizational hierarchies, not responsible citizens,” explains Publishers Weekly, reviewing the book Voltaire’s Bastards by John Ralston Saul. These are just some of the attributes of the ideology that has a strangle hold on our society and, it appears, on our major environmental groups as well.

The environment is too important to be left solely to the environmentalists.

Environmentalists with corporatist tendencies can cause a lot of harm when they are not properly scrutinized and held accountable by the public. They have played a huge role in keeping consumers in the dark regarding the hazards posed by CFLs. The Suzuki Foundation and Greenpeace claim that CFLs are good for the environment and no one dares to challenge them.

The disinformation process begins when public awareness of a harmful product, such as a CFL, is restricted by environmental groups. Over time, with no real criticism of the product, a consensus consciousness is created in the public mind that the product is safe.  Finally, in one of the oldest tricks in the book, corporations use these groups as third party endorsers to create a favourable image of a potentially dangerous product. Remember back in the sixties with doctors in TV adds smoking Camel cigarettes?

The evidence that shows that CFLs are hazardous to humans is undeniable. The question is, why are environmental groups willing to risk a safe environment and their reputations by promoting a toxic product?

CFLs Are A Hazardous Product & Do Not Save Energy

It may surprise many people to know that CFLs increase a consumer’s carbon footprint in a ‘cradle to grave’ analysis. Full costs to manufacture, operate and safely dispose of a CFL have never been disclosed to the public. The reality is that residential lighting takes up only 0.8% of energy consumption in Canada.

CFLs are energy hogs to produce, operate and dispose of. Reducing a consumer’s carbon footprint is the CFL’s raison d’être.  But before deciding to switch over to compact florescent lights it would be wise to first review a cradle to grave analysis of the carbon footprint of a CFL, compared to an incandescent bulb.

What is the real energy cost of a CFL?  What does it cost to mine, manufacture, package, ship, sell, operate, dispose of CFLs on the environment? These are questions ignored by CFL promoters.

An International Association for Energy-Efficient Lighting (IAEEL) study conducted in Denmark, explored some carbon footprint factors, but not all, showing it took 1.8 Kwh of electricity to assemble a CFL compared to 0.11 Kwh to assemble an incandescent bulb.  That means it took 16 times more energy to produce a CFL. The study did not include the fact that a CFL is much heavier and is more dangerous to handle, and will thus cost more to package, to ship, and to sell.

This research also did not calculate the energy required to safely dispose of a CFL and reclaim the mercury. The cost of removing mercury from the landfills was also not considered. More over, the potential cost in destroyed lives, illnesses, and lost human productivity due to exposure to mercury and electromagnetic radiation have not been considered.

If such a study could be done, and considered all the negative contributing factors, it would show a CFL has a massive carbon footprint, one that would dwarf a regular incandescent light bulb and it would also show that CFLs will leave behind a wake of environmental destruction.

CFLs Do Not Save On Energy Consumption

Power Factor
An incandescent bulb has a power factor of 1. Most CFLs sold in Canada have a power factor of about 0.55.  That means there are more energy losses in operating the CFL compared to an incandescent bulb.  This does not show up on a power bill but the power company has to supply more power than what the bulb is rated for. Astonishingly, CFLs can take much  more energy to operate than what is on the label and still be listed as an energy star product, something few consumers know. CFL cheerleaders seldom tell consumers that the power factor is not included in their energy consumption calculations.

Heat Loss
Energy efficient bulbs increase greenhouse gases. Because they burn cooler, they cause home heating costs to rise. "Lighting regulations (banning incandescent lights) will increase GHG emissions in Hydro’s service territory by 45,000 tons due to cross effects of a switch to cool-burning bulbs,” explained a BC Hydro spokesperson in 2009 Vancouver Sun article.

The ‘cross effect’ referred to is the loss of heat from hotter incandescent bulbs when we switch over to cooler burning CFLs.  When a 60watt regular bulb is replaced with a 15 watt CFL, 45watts of heat from inside a house is lost. If that is repeated 20 times, 900watts of lost heat now has to be provided for from another source.

To make up for the lost heat consumers have to turn up electric heating, or worse still, turning up their oil or gas furnace which will leave them consuming even more energy and creating more greenhouse gases than before they made the switch.  In the summertime, because of longer natural daytime light, both lighting and heating are used much less. In the wintertime power consumption will rise as lights go on but additional substitution heat is required to compensate for less heat from the CFLs.

Considering the lower power factor as well as the heating losses, it can be concluded that using CFL will not reduce a consumer’s carbon footprint when compared to a regular light bulb. Moreover, instead of saving energy there is good evidence demonstrating that using CFLs will increase the user’s carbon footprint.

CFLs Are Power Dumb

Lighting is a fraction of overall energy consumption and has a limited potential for energy savings.  Nevertheless, North Americans should be conserving wherever possible.  At the same time, people should not forget that switching incandescent bulbs to CFLs poses a whole range of negative environmental and health impacts with very little, if any, energy savings

An electric hot water tank consumes five times as much electricity as residential lighting.

To put lighting energy consumption into perspective, the Sector Sustainability Table listed in the Government of Canada website reports that  “Homes consume 16% of all the energy used in Canada, with lighting using 5% of that figure. Residential lighting therefore represents 0.8% of the total energy consumption in Canada. This means that Canadians are spending millions of dollars on CFLs in a fruitless effort to reduce a fraction of their energy consumption.”

It would be much ‘power smarter’ to focus on residential water heating than light bulbs.  An electric hot water tank consumes five times as much electricity as residential lighting. If hot water heating was made 10% more efficient by using inexpensive technology already available, Canadians would save more energy than the most wildly optimistic predictions of savings by CFL promoters. It would be cheaper, simpler, and have no detrimental environmental effects.

CFLs Are Mercury Polluters

More than 98% of used CFLs end up in landfills each year. That is 675 million for the year 2007 according to the National Geographic Society. Each CFL contains about 5 milligrams of elemental mercury as well as other poisonous gases.  When mercury enters water sources, biological processes change the chemical form to methylmercury which is the organic, more toxic form found in fish.  Methylmercury bio-accumulates through the food chain and once in the body can affect developing fetuses, children and adult nervous systems.

Methylmercury will not stay in landfills as it easily gets transported through the water table. Throwing CFLs into landfills will contaminate the soil, the water table and eventually the air.

More than 60,000 children are born each year in the United States with neurodevelopment impairments caused by exposure in the womb to methylmercury compounds, according to new estimates by an expert panel convened by the National Academy of Science’s Year 2000.

Beware of a broken CFL, as each broken lamp should be considered similar to a toxic spill and care needs to be taken cleaning them up. The manufacturing of CFLs also exposes workers to toxic levels of mercury. CFLs are manufactured mostly in China with virtually no health, safety, or environmental protection regulations.  Ironically, most of the electricity used to manufacture CFLs comes from coal-fired generators. As CFLs increase in popularity, mercury exposure to workers, to electricians, to maintenance personal, to consumers, to water supplies, and to the living environment, will go ahead almost unchecked.

How many resources and pollutants does it take to make a light bulb?

“The reality is, even energy-efficient products don’t always come from energy-efficient beginnings.  Consider for a second what goes into producing, powering and transporting products around the world like...energy efficient light bulbs. Until they are manufactured in a carbon-neutral way, transported on low-emission vehicles and powered in our homes by cleaner energy—green products will never be as green as they can be,” explained the World Wild Life Fund in MacLean’s Magazine.

Many environmentalists ignore these facts and instead claim that CFLs put less mercury into the environment than what would have been created via a smoke stack to generate the additional electricity needed for regular light bulbs.  This is not true.  Not all electricity is generated by dirty coal-fired plants. Even if it was, this would still be an irrelevant point given that coal fired power plants could operate with 80% less mercury emissions. In any event, it does not apply to BC where 90% of electrical power comes from hydroelectric dams according to BC Hydro. In Canada, 58% of electrical generation is from hydro and 19% from coal, according to Industry Canada.

CFLs Are Electro-Polluters

CFLs emit electromagnetic radiation, a type of energy that can make people very sick. Many people have reported skin rashes and irritation due to ultra-violet (UV) radiation. Radio frequency radiation is even more of a concern.  The effects of exposure to radio frequency radiation, as well as to high voltage spikes and transients, are known to cause illness, are virtually ignored by environmental groups and green building consultants alike.

There has been a ‘rash’ of health problems associated with exposure to electromagnetic radiation such as that emitted by CFLs.

In Sweden, according to polls, up to 290,000 people, or more than 3% of the population, have reported suffering symptoms of EHS when exposed to electromagnetic radiation.  Symptoms range from joint stiffness, chronic fatigue, headaches, tinnitus, respiratory, gastric, skin, sleep and memory problems, depressive tendencies, to Alzheimer’s disease and all classes of cancer.

Hope For The Future

Other than the World Wildlife Fund, almost all the major environmental groups have not informed the public about the dark side of CFLs. Why they behave as they do is unknown but promoting CFLs could potentially diminish these groups credibility when the facts become apparent.

Hopefully, other governments will wake up to the shortcomings of CFLs, and follow the New Zealand government’s example and change their policies on banning incandescent lights due to concerns about safety and energy efficiency of the CFLs. Germany has already restricted the use of fluorescent lighting in public places and has banned fluorescent lights in hospitals perhaps showing that this issue is too great to be shrugged off and ignored. North America appears to be headed in the opposite direction and the Canadian Federal government still plans to ban all incandescent lights before year 2012.

There are incandescent light bulbs on the market right now that last longer than CFLs and are 80% more efficient than a regular bulb.  In 2010, surprisingly, just as the market gets saturated with CFLs, General Electric is coming out with a new high efficiency incandescent bulb. They claim it will be twice as efficient as a regular bulb.

If they live up to their claims these new incandescent lights will rival CFLs for energy consumption, but will not have all the other environmental problems. Then another buying craze will begin and CFLs may begin to be phased out, leaving behind a long-term problem of mercury disposal, remediation, and an untold toll on human health.

In the meantime, the best way for you to reduce your carbon footprint is to follow your mother’s advice and turn the lights off when you leave the room.

Walt, even if CFLs were good, a ban would still be wrong!

Americans choose to buy ordinary light bulbs around 9 times out of 10.
Banning what Americans want gives the supposed savings - no point in banning an impopular product!

If new LED lights -or improved CFLs- are good,
people will buy them - no need to ban ordinary light bulbs (little point).
If they are not good, people will not buy them - no need to ban ordinary light bulbs (no point).
The arrival of the transistor didn't mean that more energy using radio tubes had to be banned... they were bought less anyway.

All lights have their advantages
The ordinary simple light bulb has for many people a pleasing appearance, it responds quickly with bright broad spectrum light, is easy to use with dimmers and other equipment, can come in small sizes, and has safely been used for over 100 years.

100 W+ equivalent brightness is a particular issue - difficult and expensive with both fluorescents and LEDS - yet such incandescent bulbs are first in line for banning 2012!

Energy?
Since when does America need to save on electricity?
There is no energy shortage, there are plenty of local energy sources, Middle East oil is not used for electricity generation.
Consumers - not politicians - pay for the energy used.
Certainly it is good to let people know how they can save energy and money - but why force them to do it?


Emissions?
OK: Does a light bulb give out any gases?
Power stations might not either: In Canada British Columbia, Manitoba, Quebec,
and in USA Washington state practically all electricity is emission-free, while around half of it is in states like New York and California.
Why should emission-free households be denied the use of lighting they obviously want to use?
Low emission households will increase everywhere, since emissions will be reduced anyway through the planned use of coal/gas processing technology or energy substitution.

Taxation:
If a reduction in use was needed (it isn't), then taxation to reduce consumption would make more sense since government can use the income to reduce emissions (home insulation schemes, renewable projects etc) more than any remaining product use causes such problems. People can still buy what they want, unlike with bans. However taxation is in principle wrong too,
at least on electrical appliances, for similar reasons to bans.

Great article! I had suspected their evils from the very start! I was disappointed with the proposed solution, (turn out the lights when you leave the room). Suggestions of what brands & models of bulbs to buy in the meantime would be exponentially more helpful.

Hope you decide to post something along those lines! I can't just live without light until GE's new bulb comes out!

Your 'power factor' part of your diatribe is BS. A bulb will consume a certain amperage at a given voltage. A watt meter is the ultimate harbinger of energy consumption 'bad news', and my direct measurements of a variety of consumer CLFs here in the states rates them within 1% of their rated wattage (roughly, W = V x A, although electrical engineers cringe when it is that simplified). I buy my power on the basis of kilowatt-hours. Every watt I consume, I buy. The CLFs produce roughly 3.5x the number of lumens (light density) as a regular bulb for the same wattage. I can run a CLF 3.5x longer for the same cost in consumed electricity as a regular bulb. The rest of your post grandstands but smells of F.U.D. Please back up your other claims with science, not politics.

Many of us have known for years, from working under fluorescent lighting, that the energy output is debilitating to humans, and probably other living things. It ain't all about MONEY...
written by victoria , September 27, 2009
Did you just take a bunch of facts and figures from a bunch of newspaper clippings and articles and plaster them all into this article of yours?

The study in Denmark that you get your manufacturing figures from actually concludes that using CFLs over incandescent lighting reduces the total carbon emissions. But obviously you didn't bother to read the entire article. If you bothered to read the rest of it, you'd have noticed that comparisons were made based on the amount of light output in order to scale the lifetime and different lumens outputs of each bulb properly. This comparison shows that even your manufacturing numbers that you worship don't mean that much, because per lumen-hour, the CFL requires less energy to produce.
written by Wilson , November 07, 2009
Regarding Wilson's comment.

.

The Denmark study did not do a cradle to grave analysis on the carbon foot print of a CFL. They just compared the manufacturing costs of an incandescent lamp compared to a compact fluorescent lamp. With that very limited examination they still came up with the cfl costing 17 times the regular lamp. If they had examined the true costs of a CFL it would show to cost 100's of times more than a regular incandescent lamp over it's lifetime. Their claim that CFL's saved energy over incandescent lamps simply is not supported by their data.

What a bunch of fear mongering!

I don't think CFBs are without their problems, but this blog is a mix of ignorance, vituperative, and old-fashioned fear. Why? What axe do you have to grind here?

For example, do you actually understand what "power factor" is? Do you realize that the grid is largely inductive, and the capacitive load of CFBs actually help the utility correct for power factor? And of course, you do realize that utilities routinely CORRECT for power factor? The "45% more energy losses" is just total bull. Have you even taken a basic electronic theory class? Well, I'm an electrical engineer who is buying none of your technical arguments, they are so full of holes. For example, how can you insinuate that ultra-violet radiation is the same hazard as the ultra-sonic radiation from CFBs -- and keep a straight face? I've put a spectrum analyzer on a CFB. You get a million times (~60 decibels) more "radiation" when you use a cell phone, and hundreds of times (~20 db) more "radiation" when you drive by a cell phone tower.

Like I said, CFBs are not without their problems. Mercury certainly is one, and the complex, long supply chain is another. But by indulging in hyperbole in a fact-free manner, you do your cause no honour.
written by Jan Steinman , December 26, 2009
Regarding Jans comment.

Power Factor, simply put is a % of how efficiently the AC power is being used. With a power factor of 50%, double the current would flow. For example, a 40 watt incandescent lamp draws 0.33 amps. (40 watts / 120 volts = 0.33 amps) This bulb, being a resistive load, has a power factor of 100%. A single tube fluorescent lamp rated at 40 watts may draw double the current of the 40 watt incandescent, but still only use 40 watts of real power. This fixture has a power factor of 50%.

How well utility companies are able to correct for power factor, how much energy is actually lost and at what cost is of concern. So just how much more water has to flow over the dam? If Jan can supply that information I would gladly look at it. But there are energy losses, it does cost money to correct power factor, and that cost does get passed on to the consumer. If I have over estimated these costs I will gladly correct this in the article.

Ultra violet radiation poses a serious threat to human health. That we can agree upon. As for the radio frequency radiation that is emitted from a CFL as well as transients, I recommend visiting web sites with postings by Dr Magda Havas on this subject. I did not insinuate that they are the same.

Cellular telephones operate at a much higher frequency in gigahertz ,or billions of cycles per second. They also pose health hazards. Many researchers agree that power density is not the only cause for concern but the frequency may be a even more important factor. Although there are similar responses by the body to different frequencies I would not compare a compact fluorescent light with a cellular telephone.
To say that this article is bull or that I am fear mongering is Jan's opinion. As far as I am aware electrical engineers have about the same amount of formal education and training as I have on the biological effects of non thermal levels of exposure to living organisms by non-ionizing electromagnetic radiation.

None.

Have a great year everyone,

re: Heat Loss
Saying that CFLs are bad because they don't waste energy (e.g. produce excess heat) is incredulous. It's like saying that the fact that this computer is more efficient than a giant mainframe I'm doing the environment a disservice. After all, this computer is producing less heat than an older one would, so I pay for it. But the way this computer produces heat is pretty inefficient compared to a space heater, so you don't want to use it in place of one unless you want it's main function (being a computer). Furthermore heat generally rises, so the lightbulb on the ceiling isn't really doing much other than heating your roof up whereas your heater will actually warm the room (and more efficiently too).

Of course all this on top of the most obvious point, you ignore times when heating would be undesired... say when the A/C is running? However much heating that bulb provided during the winter, you now have to deal with it during the summer.

Apparently you missed in the study where it stated the production footprint was less than 1% of the operating footprint. Furthermore, while the cost to make one CFL is more than one incandescent, that CFL lasts longer, long enough that according to the study that it makes their production costs comparable. (This is why using 100 plastic bags is worse than using 1 reusable container)

Power Factor: You confuse it with actually requiring the rating/pf amount. It doesn't actually consume that power though, but your right the electricity company does need to generate it on their end, however that extra energy just doesn't then just magically disappear. The real losses are from the transmission of the power. So while there are extra costs, it isn't a 2:1 loss as suggested by the power factor. If I recall correctly transmission line loss is around 1/3 of the power. So of that extra power that needed to be sent, you're losing a third of it which can be factored into the CFL's true power cost.

Of course the truth still is that a light that is off wastes the least energy

I have just realised after reading your information ,that in fact my burning skin and headaches and nausea are a result of exposure to the "obligatory" new lightbulbs. They are everywhere, in public transport, in supermarkets in the school where I work. I will now try to avoid this radiation, but what about the millions of people including children who don't "feel" the problem but who are receiving unnecessary radiation all day and every day. What can we do?

CFL's and all the rest of the greenwashing is just B.S.

As for CFL's,,, here is what I know:

1. From the beginning the manufactures have indicated a life span of 7 to 10 times a regular bulb. More B.S. I have used these things from the start ( about 7 years ago) and have replaced all lamps at least once and others over 3 times. I now write the date on each lamp to get replacements.

2. CFL's emit radio energy at the frequency of marine emergency radios. Most packages warn to never use these bulbs in these facilities. I know a ham who made a low wattage transmitter out of these things. What will the cops do in waterfront cities when no more regualr bulbs are allowed in 2012.

3. Ever notice that most CFL's are made in CHINA ?? I have good reason to believe that the Chinese cfl industry is lobbying governments worldwide to ban regular bulbs thereby forcing countries to use their products. This happens in Canada because we would not want to offend our little ASIAN criminal brothers,,,,would we?

My way to fight this product is to stockpile as many regular lamps as I can before 2012.

re: csdx , January 10, 2010

Regular heat producing bulbs in the ceiling distribute their heat when the fan is running in the furnace. That is why heat circulates in a house. CFL's DO NOT run cool. I recently burnt my finger when trying to remove one that had just burn out. Finally the A/C point. In Canada we have very LONG days in the summer which means our houses are naturally lit a very large percentage of the time. With sunlight streaming in you don't need any bulbs.

The real bottom line is that lighting a house is a VERY small consumer of power and not even worth considering. This means that it is a non issue except to the Chinese who want use to use THEIR product exclusively.

Are we sure CFLs last longer? My personal experience has been that they are less reliable than incandescents. When I see "up to" advertising, I'm usually suspecious. I want to see "on average" advertising.

Do you know of independent studies about how long CFLs really last?

written by Jim , February 22, 2010
As a quality tester for an electrical supplier, I can assure you none of the CFL bulbs from china will last their indicated lamp life hours. what happens is that the bulbs are submitted to Energy Star for testing and approval, and once they get their rating the supplier will switch the high quality capacitor for a low grade one. Eergy Star does not do random checks at factories to make sure the product is still up to grade. exception to this is the high quality bulbs from GE and Sylvania which aren't made in china they will last their indicated hours but they cost significantly more. the best thing to do for the environment is get rid of your standard inefficient A type incandescents and replace them with better bulbs like MR and PAR halogens and use fluorescent tube fixtures for shops and work areas wwhere they will last 30,000 hours for the bulb and 20years for the ballasts. also use dimmers, because dimming an incandescent bulb to 50% will increase the bulb life to over 100years of use.

also one more thing. the infrared radiation you feel from an incandescent will warm you enough that you won't feel the need to turn the heating up as much as you would if you used CFL's.
written by Chris , March 01, 2010
I have a comment for Jim, the bulb life is not the average of the bulbs they test it's the mean average let's say they test 100 bulbs 49 burn out at 1000 hours the 50th burns out at 10,000 hours and the rest burn out at 10,001 hours the life of the bulbs is 10,000 hours.

This blows me away how people think. Here we are making a huge deal about a "light bulb" that has been going though a lot of upgrading in the last 50 years. It gives off radiation, its to cool, its doesnt help heat your home. If you don`t like incandescent,CFL`s. Why are you still using your sell phone, why are you looking at your PC screen, witch we all know is "Not" good for your eyes. Why do we eat fast food, and put perseveres in food, and "We know its not good" "Nor Healthy" and we still do it. So lets all sit back "far away" from your monitor and think of "One" good thing that is good for you, and us as people. Lets stop - trying to stop people from moving on. We should not sit and tell bad things. Lets tell them the concerns so maybe we could help them fix what is bad!

You completely misunderstand power factor. PF is the cosine of the angle between the voltage wave and the current wave. 0.5 does not meant 50%. Total apparent power is the vector sum of real power and imaginary power. There is a reason it is called imaginary power, power companies have to cater for their equipment to carry this extra amperage but other than some heat loss it is not real power and power companies and industry who are billed on total demand all have PF correction in place. Energy consumed in a CFL light is easily smaller than equivalent incandescent units. I agree problems are there with mercury, lifetime claims of 7 (I agree with 3.5). Waxing on about PF may put into doubt your credibility on radiation and the other claims which I do not profess to have any expertise in.

If you enjoy railing against The Man and the thought of corporate conspiracies, help yourself, but the purported facts presented by McGinness are so wrong it is alarming. For an electrician to be so incorrect about power factor is scary. Furthermore, the US EPA has calculated that even if 100% of the mercury in CFLs were dumped straight onto the ground it would introduce less mercury into the environment than it would to create the electricity for the incandescents they displace. Power plants, coal ones in particular, emit a little mercury for every kWh they generate.

Don't be deceived by the rant. CFLs ARE a smart environmental choice (I am not affiliated with any CFL mfr, either).

Hi....just a word from where I live in the UK. We in the UK have been charged for (without asking!) by our energy suppliers an average of £45 a year so that they can send us 'Free energy saving light bulbs' to reduce our monthly electricity bills! Problem is they don't save energy in colder climates like the UK!

Thanks for reading ...if you do

For what it's worth - I have tried out cfl's off and on for about 10 years now and have never been as satisfied as with a plain old conventional bulb. They don't fit or look good in many fixtures, cost much more to buy, most certainly do not last anywhere near the claimed lifespan, take forever to 'wake up" when used outdoors in even mildly cold weather, and reading is never as good with my 53 year old eyes. And recently I went around the house with my new watt meter device and everything except the cfl's came in within 2% of the label rating. These consistently showed 3 to 4 times the rated watt consumption. After reading the comments above I'm not sure this is a problem but you really have to wonder why governments including mine (USA) were so quick to ban conventional bulbs.

Been using CFL's almost since they were introduced. Have tested many brands, though will now take note of where manufactured to avoid "made-in-China syndrome" (lower quality, knock-off pricing, other b.s.). In my experience (I track bulb life by date of installation and date of malfunction) most CFL's, across all brands, have lasted about 1.5 years apiece. To correct for possibly high incidence of negative "flukes" in my usage experience, I compared my experience with others' experiences--overall, avg life per bulb is in the 1.5 to 3.5 year range, significantly lower than wildly inflated marketing claims. Quibbles about relative levels of mercury emitted into the environment through use of incandescent bulbs vs. CFL's seem absurd--a little like debating the rates at which water was filling the cabins and common areas of the HMS Titanic as it was going down: ALL unbound mercury compounds are dangerous to animal and plant life in the environment. Hence, even the US government's EPA, controlled as it generally has been by corporate interests inimical to the public health of US citizens, has established that there is no "safe" level of mercury in the human body. (Let's ignore, for the sake of space, the curious question of bound mercury in traditional dental amalgam filling compounds). CFLs appear to be a mixed bag at best, and most of the disadvantages accrue against the consumer and the environment. Product energy efficiency, health and safety are not the problem of the ownership/managerial classes of the world, who are profit-focused. Appreciate the suggestions focusing on LED's, better quality halogens, and better quality CFL's.

One of Thomas Edison's first bulbs has been lit and dimmed since 1909, showing that we don't need to replace bulbs at all. Yet they are created (all in China now that GE has closed it's last US light bulb factory), to burn out. Why?
'Planned Obsolence". It causes manufacturers to keep us consuming, believing there is always a new and improved version of something. Changing bulbs is busy work. What's it keeping us from really working on?

Has there been any experiment to see if a CFL lamp really consume its rated wattage even after certain period of use at home, say after 6 months or a year or two? I read somewhere that over time, it become more and more power hungry.

The new bill proposed in early 2011, HR 91, the BULB Act, proposes to repeal the provisions of HR 6 that essentially outlaws incandescent light bulbs. I urge you to write your representative in support of it. Either because of personal freedom or because of the health effects, this ban must not be enacted!

my wife and i just bought some solar panels and are wanting to start watching what we burn in electicity! our electric bill was 25% more than this time last year and we had a TVA charge(probably a"coal ash spill cleanup fee" of 36$ also! So we started by buying over a 100$ worth of cfls. Problem? I just pluged one cfl in a lamp up to my watt meter and Low and behold! That 13 watt cfl was burning 40 watts!! I just emailed Sylvania for an explanation, we"ll see if they respond! either way, Im gonna takem back for false advertise ment and but some thing else like, some 12v bulbs and let them run on my solar batteries!

My home has 95% CFLs in it. They definitely last much longer than an incandescent, though you can get some pretty good long lasting halogens if you want to pay big bucks. I have had 27 cfl light bulbs (13, 18 and 23 watt) for the last 3.5 years and have replaced 4 of them. And YES THEY DO GET HOT!

As far as Mercury exposure, the figure I have heard (CBC radio from I believe a BC Hydro spokesperson) is that one CFL has about the same amount of Mercury as a can of Tuna. I don't know about all of you, but I don't eat my light bulbs when I'm done with them and I would bet you don't either. So, it will end up in a landfill. My recommendation: don't roll around in the garbage at the landfill. Most landfills In BC have taken precautions to keep any contaminants from the landfill out of the groundwater, so you should never be exposed to them. That being said it probably is not a good thing to throw a bunch of mercury in the dump anyway.

The amount of Mercury in standard fluorescent tubes is MUCH higher, especially T12s which have been phased out of new construction in BC, and there have been many incentives to commercial property owners to get rid of them and switch to T8 or T5 tubes with less mercury. I am currently looking for figures on Mercury content in the various bulb types. There are such things as Mercury reclaimers for these tubes, and as far as I know there is not a single one in BC.

I believe LED is the future of lighting (China also dominates the manufacture of LEDs). At the moment they are still really expensive and have problems with excessive heat, but I'm sure it will come with time. I wouldn't recommend them to anyone right now because of the heat issue, as heat causes rapid deterioration of LEDs and most good ones are still about $40 / lamp. When that day comes you will be changing you light bulbs once every 15 years. And switching them on and off doesn't decrease the life span!

So think about all the office, commercial and industrial buildings who generally have all the lights on all the time while they are open, and many 24/7. The power consumption compared to residential usage I'm sure would be staggering. I think commercial and industrial power consumption for lighting is a much bigger deal than residential. While many construction and electrical companies seem to be putting in high bay fluorescent fixtures in areas with high ceilings, in these situations metal halide lamps will put out more light with less energy. I'm not sure what is available for office/home lower ceilings.

Metal Halide lamps are BY FAR the most efficent in terms of output lumens per watt, other than possibly high end LED. The cost of good LED fixtures and lamps for a commercial or industrial building would likely put the builder out of business. Though they did use them exclusively in a new local high school, but that's taxpayer money so the sky is the limit. They (metal halide) also have a similar to if not better lifespan than fluorescents, though they do dim significantly over this time. I have NEVER seen a fluorescent tube T8 or T12 last 30,000 hrs as some people suggest it will, whether high output outdoor or standard and I have been working with them for 20 years. I would say average is closer to 10,000 hrs maybe less. I am in the sign industry and have seen hardly any effort to move away from T12 high output fluorescent tubes in sign cabinets to any alternative lighting. There are a small number of people using LED, but the cost is still extremely high.

I use CFLs because changing light bulbs frequently is annoying and unnecessary so why do it? I can also use 23W CFLs in places where I want more light but only have a 60W rated socket so I can`t put in a 100W incandescent. Having our government tell us we CAN'T use them? Not right. Not while the malls and skyscrapers are leaving their lights on all night long for no reason. How about a light pollution law stopping commercial and industrial buildings and complexes from leaving lights on when not in use? Or power limiting based on the type of commercial activity and number of people employed. If a large buidling goes over it's allotted usage, it pays more - alot more. Force all new construction (wherever feasible) to use Infra-red motion detector switches so lights are always off when nobody is in the room.

I do agree that more energy to produce and more mass dispose of is an issue, but it's a small one. I'm all for CFLs.

It seems that this author is one of those cogs of corporatism he writes about. Whether the author is a lobbyist for consuming as much energy as possible, or one for traditional light bulb manufacturer's like GE and Sanyo, who have billions at stake on this issue, this is pure propaganda.
written by commonsense , March 13, 2011
Sounds like you have three main arguments. From what I read, I don't think I agree with any of them, and would invite your response.


EMF Radiation

Turns out the CFLs EMF radiation is not zero but then neither is an incandescents. Or at least, if they're driven by AC the cables themselves make enough EMF that the contribution of a bulb seems negligible. Now I'm quite sure you can get high tech and quibble about iotas of something a few cm's from the bulbs. Not interested in that logic trap. I'm interested in what it means in a practical world. For CFLs most science and medical people say there's no evidence of harm, and I'm sure you can quote from the outlier studies that say otherwise. Fair enough. There were some early studies about the danger of smoking too. But it sounds like the measuring gizmos say that in a practical world where people actually are in relation to their lights, the EMF factor might as well be zero. So sounds like whatever teensy EMF might be measured a few cm's from the bulb, in comparison to the EMF that would be measured an equal distance from other bulbs, is a non-issue.

CO2

I'm thrilled to hear you call for a cradle to grave study, and I'll go one more to say it should be based on the real world longevity of 1000s of bulbs not the ideal lab longevity. Sounds like your main criticism of the Denmark study is that it left out some transportation and packaging issues. It would help if you could list the specific variables you think should be added to their spreadsheet. In the comments above you rail that no one has studied these things and then in the comments you betray that principle by making your own unsupported claim. In the comments your wrote: "If they had examined the true costs of a CFL it would show to cost 100's of times more than a regular incandescent lamp over it's lifetime. Their claim that CFL's saved energy over incandescent lamps simply is not supported by their data." Well, where's your data for the "100's of times" number? My assumptions are exactly the opposite, which is why we need studies.

Mercury

Here's where I am the most troubled by your critique of CFLs. You correctly bash the lack of a total big picture view of CO2, but then you attacks CFLs by looking only at a slice of the mercury issue. From what I read, CFLs have some mercury, which might be released or might be recovered, but regardless burning coal always releases some. It takes less coal to drive the CFL. Given the amounts we're talking about, the savings from burning less coal eventually evens out the mercury issue, so if the bulb keeps going like its supposed to, the CFLs release less. (But of course, we have to know the true amount of coal in the big picture... I agree that should be quantified)

I'd welcome your critique of my thinking, but please highlight your assumptions and provide citations for your facts. Thanks!

While you all are arguing about power levels and wattage and other things that are way over my head, take a moment and do some research on the fact that CFLs have a serious problem with exploding during common use. These explosions have resulted in fires in many places. The environmentalists don't like to talk about things like this when pushing these "green" solutions on the rest of us.

These bulbs have serious issues that need to be addressed, and what is truly frustrating is that none of the officials that try to force these type of things on us care.
written by William Snaukstas , April 22, 2011
Good article, maybe a little over the top. The US government has no business banning incandescents.
I think fire is a big point you missed. As an electrician I have put in a lot of these and they do seem to last a little longer and yes, they save kilowatt hours (i have tested this via ammeter), they also sometimes burst into flames on whim. The other big point that no one has talked about is color renditioning...this is a huge downer and it is why people just don't quite look right under cfls if they are installed in any sizeable quantity in a home. I use both at my house. Stop telling us what to do government, this is a free country not a communist green state.

As a fellow electrician in Victoria, I am glad to see we share the same thoughts on CFLs. I think people are missing the point on the power factor issue. While the wattage is lower on a CFL with the equivalent lumen output of an incandescent, the CFL does not efficiently convert the electricity to light. With a power factor of 1,
the same CFL should be 45% brighter, with no increase to the wattage. If it takes a gallon of gas to drive to the store with a v8 engine, but only half a gallon of gas with a fuel efficient four cylinder with a leaky fuel tank, is the smaller engine the better choice? If money saved is your focus, then yes.
We are lucky that where we live our power generation is hydroelectric, and while the coal burning issue does not apply to us, perhaps the CFL push would be better suited to those areas that do use coal, and our energy conscious programs focus on LED technology.

Ultimately, the CFL is a temporary bandaid solution to the energy hungry incandescent, and it will hurt when the bandaid is pulled off , both fiscally and environmentally.

Thanks for bringing an alternative view to this issue

Very helpful to one who is just finding the resources about this part.It will certainly help educate me.

Please, be more careful in your use of the term "electromagnetic radiation". It is not all bad for you. For instance, the visible light you need in order to see (from ANY light source) IS electromagnetic radiation. Even the heat given off from incandescent bulbs (which the article says lowers your heating costs) is infrared electromagnetic radiation.

As for radio waves, you are bombarded with them constantly. If you can turn on a radio and pick up any station what so ever, the radio waves are hitting you even when you shut the radio off. They are quite impossible to avoid unless you are in specially designed (and expensive) rooms, underground, or in the middle of some buildings.

If you DO have CFLs, here are the best practices for cleaning up a broken bulb. They say not too worry too much if you cleaned one up improperly before: http://www.epa.gov/cfl/cflcleanup-detailed.html

Haha, I am as much against CFLs as the next scientist, but Mr. Killmore, you cite the fact that CFLs release electromagnetic radiation as a safety concern. Just so you know, so do incandescent bulbs; the electromagnetic radiation is also known...as light. Light is electromagnetic radiation, and so are radio waves, but they are also used in MRI and are harmless. While I agree with your article on the whole, you need to check your facts before you write something like this.
