So far, they seem kind of expensive. I have been using CF bulbs in my trouble lights, and they seem to work fine. They don"t get nearly as hot as incandescent bulbs and seem to be tougher than regular old bulbs.
However sometimes you want and need the heat of an incandescent bulb. I heat my doghouse with two old fashioned 100 watt bulbs in haymow fixtures. With the bulbs wired in series, they seem to last a very long time.
When I heard about the ridiculous ban a few years ago, I stocked up on incandescent bulbs. Must have a hundred, or so, stashed in the basement. They will probably last me the rest of my life!
LED bulbs seem to work great for lots of things, but until the price comes down a bunch, I don"t think I will be buying many. I have only used them in places where it is really difficult to change the bulbs, and where the lights are usually left on all the time.
