Is this true? I have a couple of ceiling dome lamps -- metallic base with a heavy glass bowl enclosing the bulbs. Changing the bulbs is a nuisance so I thought I might switch to CFLs the next time around. I thought they were a lot cooler than incandescents so heat buildup shouldn't be a problem.
Do it. I'm not a CFL zealot, but a CFL pragmatist. Do it where it makes sense. It has cut my electric bill. The bulbs don't seem "slow" to light to me unless it's in an unheated room. You can find them on sale all the time and spend about twice what a normal bulb costs, but the life seems to be forever.
I started using CFLs about 3 years ago. I've replaced a total of 1 so far. In my kitchen, we leave the lights on pretty much all night(wife and I are up sorta opposing hours, just works out that way). I was changing standard bulbs constantly. After going to CFLs, I've had to swap out one!
