before you guys go out and buy new lighting systems check out the conversion bulbs at discount hydro (or anywhere grow lights are sold)...i've been using them for years (sunmaster) and both mh and hps conversion bulbs are easy to find and much cheaper than switching your ballasts.
btw, i use both mh and hps (1430W total) together during flowering. makes for larger, denser flowers.
