I recently replaced 4 old light fixtures with recessed lights (Halo). They are all on the same circut and I am not using a dimmer switch. The bulb in one of the fixtures burns out after about 100 hours. The other 3 are fine. Is this a bad fixture? Bad wiring? Bad circut? Bad ?????? Thanks in advance for your help!!
Before throwing away that bulb, test it in another fixture. It could be that the fixture fails when it gets very hot, making you think the bulb has burned out. It happened to a friend of mine who threw away a lot of good light bulbs.
