Most people would use some sort of special fluorescent grow lights for that kind of thing. For plants that want high light, if you don't keep the tops within a foot of these lights, you are not getting high light. If you want to step up the light, and can vent out the heat in some way, I'd go with a 400 watt metal halide. A 400 w mh can do a 4 foot by 4 foot area and produce just about what the sun will give you for brightness. You don't keep your plants that close to the light source either.They aren't all that bad on electricity either. About $30 a month or so.
