No, it won't. It will run most mogul based 250 watt probe start bulbs including XM, Ushio and Hamilton

You need to use an HQI M80 ballast or an electroninc 250 watt ballast to power an HQI 250 watt bulb.

Between those two ballasts, I would recommend the 250 watt HQI 80 ballast. Electronic ballasts under drive HQI bulbs. You will get better bulb performance with an M80 HQI ballast.

correct grigsy. I have this ballast and went with 20k xm and it's awesome! Very crisp blue color, which is just what i was wanting. I wanted the effect of nothing but actinics, but i really needed major metal halide upgrades
