The only complaint I have about the lamps, as I said in another thread, is that you can't dim them. Since most all of our lighting is from cans and fans on dimmers, they don't do much good for us.
We've got them in our backyard deck lights and a few lamps in the house that may stay on for many hours at a time like the one in the foyer that stays on overnight a few nights a week. Don't want to come out of the bedroom and stumble down the stairs or anything like that.
BTW, the wife doesn't like them since they don't have "cool" or "soft" light.
