Hello everyone. I am currently running 2 X 20 Watt actinic florecents and I am upgrading to 2 X 75 Watt VHO actinics. I bought a new ballast, a Workhorse 7. Does anyone know what the proper wire configuration would be. The manufacturers web site shows alot of different variations. There are 4 red wires, 1 yellow. I am assuming that 2 red to each bulb with the yellow in series back to the ballast.
The Ballast is an electronic ballast ratted for 220 watts.
Any hints?
Thanks
