i was looking on the ballast and i found this sticker with this on it:

MH

175w 60 hz
250w 60 hz
400w 60 hz
1000w 60hz

HPS

250w 60 hz
400w 60 hz
600w 60 hz
1000w 60 hz

would this mean it can run those wattages of bulbs or what does it mean.
There was also little boxes next to them with the 400w 60 hz MH box checked so i think its a MH light i dont know
