Does anyone know which lamps are connected to which ballasts in the fixture? I'm not sure which generation my light is. Maybe [MENTION=364823]Keith@ ATI NA[/MENTION] ?
Channel 1 as far as I can tell is lamps- 1,2,7 & 8.
Channel 2 is- 3,4,5, & 6.
5 and 6 are not working. I'm wondering which lamps are connected to which ballast. Are there four ballasts inside the fixture. 2 lamps on each ballast?
Each ballast does indeed run 2 bulbs. It should be between reflectors 5&6 but I would mark the end caps in question with some masking tape or similar so when you bring the light down to review it you don't get mixed up with 3&4. Your best bet is to follow the wires back to the ballast, to ensure you replace the proper one.
While this video is for the T5 only Powermodule, the process is the same. Also, while not stated be sure you remove the cover on the ballast so it can fit just like the one you pull out.
