I think they're great. They're not as bright as standard lights, so depending on where you put them, you might want to mix the standard in with the LED. Looks nice together.
Question though, is it ok to use outdoor LEDs inside? I did last year and had no problem. What really can result from that? I wanna use them again this year for the stairs. I dont see what the issue would be, because they don't get hot like some outdoor lights do, which is why you wouldn’t bring those types indoors.
