Should i flower with this light?

check it out on ebay heres the link... 400 Watt Metal Halide Aquarium Light w/ Choice of Bulb! - (eBay item 180186681493 end time Dec-09-07 12:37:01 PST)

I use T5 for my whole grow, but as far as I know MH is more for veggin and HPS is for flowering, ...for a real decent 400W HPS check out these guys...High Tech Garden Supply

ok thanks.
