Get yourself a lumatek or maxibright digital/dimmable ballast.Whats up friend... My question is: Because i have a 400w mh and a 600w hps " can i use the same ballast?
I have the maxi bright. It has settings for 400, 440, 600 and 660 watts. You can run a 400w HPS on 400w and 440w and a 600w HPS on 600w 660w.
It will also run mh bulbs, but i believe they need to be on the correct setting ie 400w for 400w bulb and 600w for 600w bulb.
Hope that makes some sence. I payed £130 for my maxi bright. I've seen lumateks for 120.
