MH ballast

[annewayne]

I recently bought 4 MH ballasts with no hardware for next to nothing. They are a Universal mag.ballast that states to use 1- 70 watt M98 lamp or 1- 75 watt M101 lamp. I've been on numerous sites trying to figure out what to do. None of the sites use these lamps.I was wondering if a reg.HQI 70 watt lamp would work? I would just buy the hardware and lamp but i would have about 105.00 per ballast. thank you for your help....

If there were a much cheaper way to go to MH, you'd see more people doing it

I don't think trying to pair a 70w HQI would work like it's supposed to. I'm no expert though.
