Sometimes CFLs are the only real option

I have seen a few letters telling people not to use CFLs because they have mercury in them. What is not said is that all fluorescent lamps contain mercury. Actually it is mercury vapor as the mercury is vaporized during the manufacturing process. I guess we will have to eliminate the thousands, possibly millions, of tubes already in use in office buildings and schools, etc. Not realistic.

As for those off grid, like me, they are necessary as incandescents use too much power.
