Has anyone had hood light problems like this, my flouresent light gave out on my twenty gallon tank, so I went down today and bought another one. Got it put in, turned the light on and it worked, for a few minutes, then went out. I took the inarda apart, and there is a starter in it as well as a transformer looking piece. Can I test these with a volt meter and get a good read out. I have no idea if I can even get replacement parts. Likely have to replace the light part. been thinking of just buying another flourescent fixture from Home depot. $16 bucks for a new tube is expensive. Home depot carries this stuff, and it's a lot cheaper. Will appreciate any help anyone can offer.
