A bulb lasted less than 2 hours. The rest was fine. They are used in the lamps that I rent out. If I could I would get rid of devices that have this. I have a low ceiling. Incandescent bulbs generate a lot of heat, are short lived and expensive if you have a 5 bulb light fixture and a 3 bulb light fixture. They are usually out of stock at my local big box store. I'm sure there are other low-cost rental companies around that put these cheap $30 lights in apartments that cost renters a lot of money for the bulbs.
