Combination HPS / MH light. Have you guys seen this?

[GaGrown]

Sorry if this is already well known amongst everyone (Which it probably is, I just don't know cause I'm a NOOB) but, on the off chance it could help some people out, check this out, 600W Future-Brite HPS Electronic Ballast 120V It's a combo HPS / MH with a built in cooling system which I plan on getting, so I can use it for vegging then flowering. Tell me what you guys think, lemme know if it would be a good buy, (I already know buying stuff off the internet is a risky deal, ie. paper trail, etc.)

P.S. It comes in 400 watt also, I dunno if it comes higher or lower than 400 and 600.

I use Future brites..That system is BAD ASS! Future-Brite is the Future! When you say combo,are you saying they can run a MH and HPS at the same time? Because they can't! You have to use a 600 watt conversion bulb... There is no such thing as a true 600 watt MH lamp/bulb.As far as the paper trail....... Just buy from a well known establishment that cares about their customers privacy..
