Aquarium lights
Just to keep posting...
I had 2 aquarium lights: 18", 15w, T8 Bulbs... both burned out within a few months. some similarities that I noticed: Ends would sometimes turn orange for a second before turning on, ends have dark rings on the inside of the bulb, would sometimes flicker when starting soon before they died.
I think that one was "Actinic?" 10k , the other was 4000-5000k...
Edit: I tried both lights in another fixture, the 5k bulb turns on & the 10k bulb flickers.(ballast problem?)
