Derry Posted February 25, 2009 Share Posted February 25, 2009 Yes, it's been a bumpy few days for the ol' fish tank. After two pump failures in two days and the loss of a green monti to agents unknown, I noticed today that two of my T5 bulbs aren't coming on. I'm running a Tek Light with six 48" bulbs. All of the bulbs are less than three months old, and the fixture itself is less than two years old. The attached graphic shows how the two outer lights are wired together as a unit, while the four inner lights are wired together as a second unit. The two bulbs in the inner unit marked with a red X aren't coming on. I swapped a working bulb with a non-working bulb and verified that the problem is with the fixture, not the bulb. Can anyone tell me what might be causing this and how to fix it? I'm not a total electrical noob, but I've never cracked one of these light rigs open before, either. Thanks!
