My question is it possible for half of the unit to quit while the other half sill work? I had it set-up for 4 bulbs for over a year and when I changed bulbs it worked for about 1 week and two of the bulbs won't light now. I've tried changing the bulbs around and checking for loose wires. The only other thing that comes to mine is that the ballast is bad. Does anyone know of such of a problem. Thanks
