Compact Flourescent Light Bulbs

I had the following comment on my Earth Day posting this past week. I never thought about the fact that these new compact fluorescent bulbs contain mercury. I had heard that the big fluorescent lights had nasty stuff in them, but I didn't put two and two together regarding the smaller bulbs.

Something to think about people! When we think we might be doing something good for the environment, it could be that we are helping in one way (energy conservation) but hurting in another (potential contamination of soil).

Do your own research . . . don't take it from me or Johnny 5. Johnny brings a more informed opinion than mine, but it's just one opinion. Go out there and research it for yourself so that you make the right decisions. I know I will

Thank you Johnny 5 for your post! It's great when we can get conversations started.

As someone who sells light bulbs for a living, I am less enthusiastic than most about compact fluorescent bulbs. This is due to the fact that the ones currently available contain significant amounts of mercury. If one of these bulbs should break inside of a person’s home, it could cause a challenging disposal situation. It is my belief that the technology should progress to a point at which the mercury levels are low or nonexistent before people changeover their entire homes. Another consideration is that as these bulbs burn out, they will most likely be thrown away as though they are normal rubbish and landfills will have incredibly high levels of mercury in their soil as a result.

Mercury? I would wonder what that is in my language, because I do not quite know what that mercury means. (of course I know that it is a planet :-))
I'm starting to think, that the more is the thing complicated, the more environment unfriendly it is... I mean the device. The thing it is doing might be good. Just like solar panels... They may low the need of electricity, but their production is not so environmental friendly...

Most CFLs today on the market contain less than 5mgs of mercury and there are CFL options out there that contain as little as 1.5mgs of mercury- which can hardly be called a “significant amounts of mercury” considering that many item in your home contain 100s of times more of mercury including your computer. Mercury levels in CFLs can never be “nonexistent” since mercury is a necessary component of a CFL and there is no other known element that is capable of replacing it. But CFLs actually prevent more mercury from entering the environment. According to the Union of Concerned Scientist, “a coal-fired power plant will emit about four times more mercury to keep an incandescent bulb glowing, compared with a CFL of the same light output”.
