Ahhh, Compact Fluorescent Light Bulbs, how some people love to hate them. C.F.L.’s, throughout their short history have been both the boon and the bane of the environmental movement. They are the one thing that the common every-man can get behind. By going to the local hardware or even grocery store, billions of people the world over have literally bought in to the Environmental movement. At the same time, not buying them is an easy way to declare you’re independence against Environmental Guilt
As many of us know, C.F.L.’s are up to 13 times more energy efficient than incandescent bulbs. The reason for this is that 90% of the energy consumed by an incandescent bulb is wasted heat. This makes the bulb extremely inefficient. (And hot to the touch)
So why doesn’t everyone run out and buy C.F.L.’s? Well, here are a few reasons.
- C.F.L.’s cost more than incandescent bulbs. True. (But) For a given light output, C.F.L.’s use between one fifth and one third of the power of equivalent incandescent lamps, and last anywhere from 10 to 15 times as long. The cost saving’s between the actual bulbs themselves and the energy saved can result in a 10% to 15% total electric household saving’s over the course of 30 C.F.L.’s life. (About 5 years)
- C.F.L.’s don’t put out as much light, or as good a quality of light as incandescent’s. Just
like anything else, new technology is dictated by many things, price and demand being the two big ones. But many people don’t want to even think about new technology until it’s out of the box and perfect in every way. These are the same people who wont buy a new computer because in 2 months it will be obsolete. When C.F.L.’s first hit the market, they did not offer all the choices in light quality and output that incandescent’s did. But the last two years have seen every lumen of light become available that incandescent’s have offered.
- C.F.L.’s contain the Mercury. This is absolutely true. But lets put it into perspective. There have been horrendous reports of how C.F.L.’s are not safe. “If you break one, you’re in big trouble!” This junk science has been propagated by the Media because it sells newspapers and keeps you in front of the T.V. The truth is C.F.L.’s contain a very small amount of mercury sealed within the glass tubing – an average of 4 milligrams – about
the amount that would cover the tip of a ballpoint pen. By comparison, older thermometers contain about 500 milligrams of mercury – an amount equal to the mercury in 125 C.F.L.’s. At the same time, new “Alto” C.F.L. bulbs are now available with even lower mercury content and can be found at this online store. - There are not enough models out there. I have different size light sockets. Check this out.
In closing, time marches on, and what may have been two or three years ago, is not, today. Please don’t be so quick to judge based on Rumor, E-mail’s, Television or even word of mouth. Seek the facts, live the change.
Thanks for stopping by. Please look around and feel free to comment or share some of you’re own knowledge with myself and others, and as always, keep up the good fight and Alter the Eco!

Hi Adam – I really love your blog but I have to say you are touching on a very controversial topic. Last year I dropped a CFL on the way home from the store while it was still in it’s original plastic/cardboard packaging. It broke. I immediately tossed it in the garbage without thinking about it too much. At the time I wasn’t aware of the mercury issue so I wasn’t concerned. A couple of weeks later I was having some blood tests done and had a liver test anomaly – way out of whack. I can’t absolutely say that it was due to the broken CFL but it seems likely.
Just because the mercury level in thermometers is much higher doesn’t mean that CFLs are safe. Thermometers may be constructed differently. I don’t believe it is possible to break a thermometer so easily as it was to break a CFL. Thermometers are approved by the FDA and therefore manufacturers have to comply with rigid standards. Whereas CFLs are manufactured in places like China where quality may be substandard, anything goes and no FDA approval.
The fact that the amount of mercury is the size of a ball-point pen head is not particularly meaningful considering that mercury is one of the most dangerous substances around.
And ignorance/laziness will lead most consumers to discard CFLs in the normal garbage disposal. What will eventually happen is leeching of mercury into water supplies – we already see the effect of mercury on fresh water fish. It will get significantly worse with CFLs being pushed the way they are.
Anyways I have to disagree with you on this subject but I still believe you have some top notch posts. Keep up the good work!

Steve, thank you very much for the comment (and the compliment)!
I read you’re comment while sitting at my desk at lunch, and mulled it over with some awesome omelet leftovers from last night’s dinner. The more I thought about it, the more it bothered me. (Not you’re argument, but the way I think.) I had to ask myself a few questions.
Why is it that I can genuinely upset when I see someone walking down the street with a single serving water bottle, but I’m not concerned about the mercury in a c.f.l.?
Why am I concerned with the health of the children in the house of a parent who sprays weeds with roundup, but not with the health of the same children who breath mercury fumes when a c.f.l. breaks?
It’s an interesting dichotomy, isn’t it? Bothersome. Do I need to change my view? How about this?
My 30 minutes of free thought have led me to this conclusion:
Some things in life, to some people, can become Iconic representations of something bigger than they are. An example of this is over-consumption and affluenza being a representation of success and “making it.” This is a grandiose example, but bare with me here.
C.F.L.’s were my “awakening” to the green movement and the environment. I lived just like everyone else, spending my money on things that would “make my life better” at the cost of the environment and society in general. To me, as silly as it sounds (and I didn’t even realize this till a moment ago) C.F.L.’s have become a representation of the “Environmental Movement”. Something worth fighting for and defending. And to that point, it still is.
But with that being said, I must conclude that the danger of mercury should be something that should be considered. Should it keep us from buying them? No. Are they safe? Yes (as long as properly disposed of). Should people be aware of the mercury in them? Yes. Should people be as scared of them as the media would have us believe we should be? No.
So I’ll meet you in the middle on this one. O.K.?
Thanks Steve
Adam
So when the earth contains Mercury, since that where it comes from, why is so little of it so dangerous. In areas of southwest Texas they mined the raw material for mercury and distilled it out of the rocks, large portions of the area contain more mercury in the ground than you would ever get exposed to breaking a florescent lamp tube even the big ons. There are lots of chemical compounds that are naturally occurring but are labeled as dangerous. What do we do force relocate people away from “dangerous” materials in the ground. We have large areas for lead and zinc in the Missouri, Kansas, Oklahoma area. Lead is under attack as not minimum safe exposure, do we all move at the governments forced request. Who pays for it?
You cannot separate yourself from the earth, it is not healthy, you just need to not be stupid.
Interesting argument Paintman.
I don’t think anyone is advocating that the Gov. force or pay anyone to move. People live where they choose to live. It’s on them. Coal miners decide to mine coal. Artisinal Gold miners choose to use mercury to separate gold. Car battery recyclers choose to break them apart with sledge hammers. Sure, there is a demand for Nuclear Power, but the people who mine the Uranium do so because they choose to.
Sure, we have to be one with Nature, but it doesn’t mean that I have to advocate any of the above, just like it means that I don’t have to live next to a live volcanoe “Unless I Want To,” and if I do, then that’s on me.
Thanks for the comment!
I just bought a CFL bulb for my computer room to replace a 100 watt bulb. Light output was not as great even though the box said it was equal to a 100 watt bulb. I then bought another 100 Watt CFL bulb and put it a two bulb adapter. Now it approaches the same light level. So this is one myth of the CFL bulb, that it puts out same light. You need to remember this rule if you are replacing a incandescent bulb, get a CFL that is rated at double the wattage of your old incandescent bulb. Now I have not measured light output with a light meter, but with just my eyes.
Also, there are electronics in the base of CFL bulbs that can burn. The bases get hot from the electronics. The bulbs get hot. I just this minute put my hands on both the base and bulbs of the CFLs and they are too hot to keep you hand on them after less than 30 minutes of turning them on. I would never leave my home with CFL bulbs burning due to the electronics in them for fire hazard reasons. Maybe they wont escape the cover, but I wont take the chance!
Also some of the CFL bulbs are not to be used in a base up position as this lets more heat from the bulb heat the base of the bulb and it dont need more heat.
Also, I believe that 90% of them will go in trash when they burn out, and from what I hear, they do not last as long as they claim. More polution for our landfills.
Lastly, the Chinese must be in hog heaven at the thought of the entire USA switching over to these bulbs, they will own us, maybe already do! Why dont we make them in the USA? Well, mercury in them(enviromental), too many wage/benefit issues. Same reasons nearly every mfg job is going overseas where wages and polluting factories dont make stop them from producing. Had we had all the wage/enviromental rules in place 125 years ago, the USA would be a third world jungle as we are now becoming.
For sure CFLs have advantages..
but the savings you mention have been exagerrated..

Similar with the heat effect

Today people buy ordinary light bulbs around 9 times out of 10 (lighting industry data 2007-8)
If new LED lights – or improved CFLs – are good,
people might actually want to 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.
