Might be a Universal. Aren't GE's fluorescent ballasts made by Universal? I know their replacer HIDs are. Cooper and AEL use Advance drivers. It seems Advance is the biggest Induction and LED driver manufacturer.
I'm not sure exactly how they work. The ones I'm installing on the job site have these wires too, I know if you put them together it does dim the lights.
Ah I see. I've wanted to experiment with the dimming function but the ballasts don't specify how to wire up the dimming function. i assume it required a special device or something. I don't want to risk frying the ballasts trying to figure out how to dim them lol. I'd guess with fluorescents that dimming them would probably make them die faster. Obviously with LEDs this isn't an issue and if anything, they'd last longer just like incandescents. I'll bet anything that the driver will fail long before the LEDs (and if the LEDs do fail, it's probably a solder joint gone bad and not the diodes themselves; the LED itself is very basic and not complex. It's the driver that's all complex lol).
