Any ideas on if my ballast is failing or the bulb is going out, If watching the tank the brightness shifts on occasion as well as the color temp.
Thanks for you ideas

It is most likely the bulb. There is a chance that it could be the ballast, but if they fire, then they usually keep firing.
What kind of bulb is it? I have extra that are near end of life that I can mail you if it is 250w SE or DE.... just to test and see.
EDIT: I have seen cheap Chinese bulbs just shift color right before your eyes as you were watching them - similar to the color shift as they start up. This was on some older bulbs, but it was so freaky that I had to go to a friend's house and see.
I had been watching them, going back and forth on if I want to have them to only loose them again or to go 14K MH / T5 combo to get the pop in the 400 range.There are a pair of them on eBay right now for $120.
