They were so pretty and bright enough for my needs that I've unfortunately put off using them (and my return window only closed a few days before I tried them). I loved her but I went out the next morning and one light was already out. I went and asked the dog to get it out and when I did and came back I noticed the second light was flickering. I looked at it and it blinked a few times and then burned out. That is at least 12 operating hours. They were great when lit, the fixture listed a 60 watt bulb max so I don't think that was a problem, for the price I definitely wouldn't risk it again.
