Electrical Wiring in the Home/Flourescent Light


I have had a flourescent light in the bathroom for years. It stopped working even with new bulbs. It was old, so I bought a new flourescent light. It worked for a month, I replaced the bulb, and it worked about another month. I took it back and got a new light (same type).

I have the same issue. At first, I thought it was the ballast, but the problem continues even after replacing the light.

I used an electrical tester, and enough volts are coming in, and there do not appear to be any problems.

This light is not too far from an a/c vent. Could this be the problem?

If I just buy a regular light that uses led or incandescent bulbs, will this problem continue or is it simply a flourescent light problem?

I do not know what to do next.

This is an unusual problem
I cannot see the AC vent causing this, as I expect that the lamp is shielded or enclosed, not that it should matter
Tell me about the fluorescent fixture and the lamps involved, manufacturer, source, model number
Aside from that, I have found that incandescent lamps always work
