I just noticed 2 bulbs in my 4 bulb T5 AquaticLife fixture are out. It actually has 8 bulbs, but it's 6' long, so has 2 sets of 36?" bulbs. So, these bulbs that are out are both in the #3 position and I'm wondering...
1. Is one burnt out (only 4 months old, Geisseman) and the other isn't working because it's "in line" with it?
2. Is the ballast out? I really don't know what a ballast is or how it works. I've read enough to guess it supplies power to the bulb, but I don't know how....
3. Some other variable?
Also, one of the moon light LEDs is flickering. How do I fix it? (Light bulb! Lol) Does that have anything to do with the other bulbs being out?!
Thanks for any help!
