T-8 is what size it is. Old ones were T-12s which I have two cases of.

Well I believe that to be a T-12 type of bulb. Replace the bulb that is half lit, and see if that fixes it, if not replace both.. if no fix. replace fixture.. it is as simple as that.

I recently bought a replacement fluorescent for our kitchen. It appears that fixtures for T12 bulbs are no longer available. The T12 bulbs are available but not the fixtures. So I bought a T8 fixture. T8 bulbs are much brighter and about the same cost as T12.

OK, I will try replacing both bulbs (since they are both dim) and see what happens.

Its the bulbs they stopped making. I stocked up with 75 and 100watt Bulbs. Can you still buy flood light Bulbs?

Cheap 4 foot T8 fixture is about 17-20 bucks. I also had a case of T12 bulbs, but could find no fixtures. After changing over,I like the T8's better
