I hate them because when I turn the light on in my closet I have to go away and come back later in about 2 minutes after it has “warmed up” so I can see anything in my closet.
Waste of time. I say, “let there be light!” immediately.
It's not only the warm up time.....if you don't leave them on for a certain amount of time, they use more energy then an incandescent bulb, and don't last as long.
