I used them on our camper. The old lightbulbs were very hot, these hardly ever get warm. And they are many times brighter than the old incandescent bulbs. The worst part was that you couldn't tell which direction they were going. Simple solution: plug it in, switch it on, if it doesn't work, unplug it. turn it over and put it back in place. Of the 35 installed, I noticed that one started to flicker a bit after about 2 months of frequent use. I don't know if it's a little loose or a little damaged but I'm very happy with these bulbs!
