Can i make a hps convertable to a m

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.

just buy it all from ebay HTG supply, came in like 4 business days

A HPS to MH conversion bulb is used in a HPS ballast but shines the same color light as a MH.

Make sense?

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.

I got ya. But even though the visible light will be same colors will i still get the advantages of using a MH for vegging and HPS for flowering?
