My entire house has these bulbs - including the outside flood lights. House is 2212 sqft and we operate the entire houses' lighting needs (inside and out) on the equivalent of approx. 7 standard light bulbs rated at 60 watts each. And no - they do not put out heat so if you're looking for a heat source, you're going to have to find something else to provide it.
Yes they contain mercury but I've never had one break (we've had ours for 3 years (the oldest ones now)) and just added a ton more and we are very very careful. The way I see it (and the age I grew up in - as most on here did I"m sure) - when I was little, I used to play with a mercury thermometer when it broke (yeah..I remember doing that..pushing those little silver balls around on the floor - "Hey Mom...watch THIS!"
We survived lead paint on everything including our cribs, we didnt ride in car seats either, drank out of garden hoses, ate raw hot dogs, bologna, cake batter, and didnt have anti-bacterial soap either. I'm still here as are countless others.
I think sometimes we take things a little too far and we've become a "germaphobic" society. Now that doesnt mean I dont use antibacterial soap LOL - because I do...and yes, I tested my house for lead paint (it is nearly 150 years old after all) and had a blood test ran for lead levels (yep, I freaked out just like everyone normally does) and yes, I have fallen victim to "society's standards and practices" just as everyone else has. But - its funny if you think about the way things are now going backwards - everything is now "probiotic", holistic, the trend is now organic (uhm...wasnt it like that years ago?), unprocessed and unbleached... . Uhmm..
Okay..sorry..just sort of went off there..(zooooooooom!)
Guess that milk thread posted earlier sort of got into my brain there...
ANYWAY - I think we'll survive the mercury in the lights - just as we did the mercury thermometers as kids. And - I still use one of those on my children, its tried and true...and yes...my peds dr freaks out every time he hears I use it
- yet I ask him "and what did YOUR mother use..hmmm?" That ususally shuts him up pretty fast
