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”.

I won't be changing them too soon! And as I said. I don't use them all at full power TOO often! They are controlled by push-button electronic dimmers, so I guess I must experiment, but first I think I'll check the science.
