Re: CFL database

Oh, come on..  you're back peddling!

I have 4' flor fixtures in my house, and have had them for 20 years!
Lights over my workbench for example!

Same "hazard" exists in my house, even without CFLs.

"workshop lights" at HD or Lowes..  How many times have these been
involved with HASMAT type stuff that you've heard of?  Why are they more
or less dangerous than CFLs in the home?  Provide proof and not just
spout your own opinion!

I'll content that's there's MUCH more mercury in a 4' tube than a 15
watt CFL.  Do you not like CFLs as you resell incandescent bulbs?
That's the only sense I can see in your argument!
