The light is pretty useless. They call some of them ultra bright. More like ultra shite. They give a really strange eery blue light in most cases. Feels like your working on the poltergeist film set!!!!!!!
I think leds are more used as they are cheap to run but if your using them in other folks houses it wont matter to you. I changed all my lights to led in my house and find it is a very funny white light you get from them and not a warm glow you get from other lights.
