I have 2 48" overhead fluorescent fixtures that have stopped working. One stopped working, so I took the bulbs out and put one in a second fixture that was working. Both that bulb, and the originally-working bulbs in the second fixture, now don't work. I don't know if it is all bulbs or bad fixtures.
These are inexpensive fluorescent fixtures that stay outside in my unheated (but dry) pole barn. It was not cold today, so the starting should not have been an issue. Identical fixtures in the barn worked fine today.
Is there a way to test the bulbs before I buy replacements (I thought putting a bulb in the second fixture would do that) with a voltmeter? I obviously don't want to put new bulbs in an old fixture that might ruin them.
Alternatively, are the fixtures just probably bad and can they be tested with a voltmeter?
