Ok, so I took the tubes out and looked at them, then put them back in.

Some notes: Only one has a dark spot (not all round the end of the
tube, just one dark spot in the side). More importantly, the
connectors that the tubes sit in are all black and melted looking.

I think this calls for a fixture replacement.


Thanks.

Hi,
4 lamp fixture? Then inner two and outer two work as pairs.
One bad will make borh lamp stay off. They're cheap. Just replace them
all. I like daylight lamps.
