Probably just procrastination, but I decided it's about time. One of my issues was that I have a lot of enclosed ceiling fixtures. I'm aware that LED's don't like heat buildup. A lot of engineering goes into heat dissipation in any LED application, even flashlights. Most of the models I've seen have warnings about that, but at least one says it's okay for fully enclosed fixtures. Also, I was skeptical about color rendering. So I ordered 12 60 watt equivalent TCP brand bulbs to see. They claim they are okay for enclosed fixtures. I guess we'll see. I replaced 12 of my old CFLs the other day. I'm happy with the color (2700 K) and frankly, the brightness gets pretty close to the 100 watt equivalent CFLs I've been using and the color is better. And gee, instant on! How nice is that? So I ordered 18 more which pretty much gets me fully LED now except for some 4' fluorescent fixtures that can wait. If anyone cares to comment about the enclosed fixture thing, I'd like to know more about that. I don't want to see output efficiency or lifetime suffer in those applications. I'm disappointed that 100 watt equivalent bulbs are not ready for prime time, as I like bright in the house. But I have a couple of table lamps that are large enough to put a two-bulb adapter into. That helps some. Who else is pretty much fully LED and what has been your experience? So far, I like them. But I'm curious about others' thoughts.
