dual 250 W M58 ballast available


New member
I have a dual 250 W ballast available for MH lighting. It is the "probe" style, so it won't fire all bulbs but gives the highest PAR for XM bulbs. It will also fire the Chinese bulbs, Hamilton, and other American bulbs. I made it from Advance transformer ballasts and enclosed it inside a metal box for safety and heat dissipation. $80 is what I'd like to get for it, which is less than the price of a new single ballast and about the price for a single DIY ballast w/o the enclosure and cords. It includes power and lamp cords as well. Thanks for looking.
