These lights look much better than the small Christmas lights I had hanging up previously. I was worried about hanging them indoors close to the ceiling because of other reviews saying that they get hot after a time. Luckily, I have not found this to be a problem at all. They run much cooler than a standard lightbulb. My main complaint is that the clips are a bit flimsy, which made putting them up with a supporting wire difficult (they fall off easily, definitely WAIT to put the bulbs in until the cord is completely secured.)
