I have a current USA Orbit 192w pc fixture. I've had it for about two years and using a bulb for about 1 1/2 years and another half of that time. Then all of a sudden the bulb flickers and goes out. I put the spare bulb in and IT wouldn't get bright tried the bulb in the other slot it works fine. Tried again in the slot the bulb was in...just a dull glow. It's the slot that the fan uses, the fan still works but the bulb just doesn't get bright like the other slot. Having mechanical background I take the fixture apart to see if I find any obvious problems...everything looks good no corrosion, no loose connections what is the deal?? Could the bulb have messed up the ballast when it went out?? I think not because a lot of people would have that problem?? Can someone please Heeeelllllp? Thanks
