    It sounds like your ballast can do both, but wait till Boss checks in, and he can confirm for you.

    seems strange that your ballast lists all different wattages. Do you have a brand and model #?

    That is a generic cover that should have a stamp under the 400. That label won't tell you if it's switchable. Is there anything else on it?

    Can you take some photos? I hate to give you bad info. But it sounds like a 400 mh/hps, but does it have a switch?

    My Hydrofarm ballast can run both hps and mh and there is no switch. My ballast is an ANSI 59 certification so I just buy the bulbs that use ansi 59. I was able to get my 400 watt MH from Home Depot for about $40 bucks if I remember correctly....
