Thanks guys for all the feed-back. Does anyone know if the presumptions:
A). black on 1 end indicates a ballast problem
or
B). black on both ends indicates a tube problem
hold any water?
Thanks again.....Mac
I've been told if a fluorescent tube is black on one end, the fixture has a ballast problem. If the fluorescent tube is black on both ends, then the tube was the problem or in other words, the tube is defective.
Also, the blackening of the ends is what burns out ballasts?
Any feedback on...
