I saw some 400w hps/mh lights available. The switch able hps/mh lights are about 40$ extra. I was wondering besides the bulbs them selves what would it take for me to coverts a hps to use a mh light ?
ebay i bought a 400 wt mh/hps system hps system with a metal halide conversion bulb, all said and done it was $205, the shipping was friggin 40 bucks, but still save about $250 extra by not getting ripped off by a hydro store.
A HPS to MH conversion bulb is used in a HPS ballast but shines the same color light as a MH.
A MH to HPS conversion bulb works in a MH ballast but shines the yellow light of the HPS.
I think thats the site.. somewhere on there it says that MH can be used in a HPS ballast, not the other way around. Never tried it but there is a lot of excellent information on that site.
