Workhorse 7 ballast for VHO.

[fishboy]

I've had my workhorse 7 running for a couple of weeks now. I'm very happy with it. I'm overdriving 3 36" NO actinics off of it. The heat off the ballast isn't that bad. After running all day it's warm but you can still hold your hand on it without a problem. I have it wired to power one bulb off one lead and the other two bulbs are powered by the remaining three leads with the bulbs in series. This combination makes my 250W Iwasaki look nice and white. I don't think I'll bother trying a vho bulb as I'm pleased with the results. Hmmmm, well maybe if I have some extra cash in the future [img]images/smiles/icon_biggrin.gif[/img]

This picture shows the bulbs in action. The two on the left are in series(165W) the one on the right is by itself(55W).
