I purchased this lamp and put it in a deep dome, vented, ceramic socketed hood. The bulb lasted about 12 hours. This was plugged directly into the wall outlet. I got a replacement lamp from Amazon shortly after. This was put in the same hood, same location etc. This one lasted about 7 weeks with about 9 hours daily use.For the money this life expectancy is horrible.The lamp is parallel to the floor, not tilted or anything odd. The lamp is not touching anything, does not get misted or even breathed on yet the life is so short. I do not have any thing between it and the power source.I really was hoping for a good lamp/brand here.
