FS: Workhorse 8 ballast

[Tarolisol]

I have a work horse 8 ballast currently set up to pwer 2 65 watt PC but can be used for any number of combinations up to 220 watts. Perfect for a DIY project. 75 dollars OBO.

What is the difference between a WH 7 and a WH 8? I didn't even know there was an "8" model (both seem to be 220W, weird).

WH8 is the new WH7. I think the WH7 is discontinued now..
