dawn/dusk with one IC660?

[lessthanlights]

Is there any wiring config- even is it's not standard, that can give me independent control on each pair of lights on the Icecap 660? I would hate to get 2 ballast for something so simple.

They sell a dimmer for the 660

I'm looking to put t5's on it so dimmer wouldn't work.

In simple terms, no you can't. The 660 can run 2,3 or 4 bulbs, but they're all on or all off. If you have room, do what I did and run 6 bulbs. 4 on the 660 and 2 on a regular T5 ballast. I have 3 whites and a blue on the 660 and 2 blues on the regular ballast. Gives me dawn/dusk since I have the blues stay on after the 660 turns off.
