not to be offensive man but that light looks like a p.o.s. especially for 75 bucks not including shipping. you could grow seedlings with that light. but def not fruiting plants. if you really wanna get your game right go with humboldt's suggestion. step up and get a HID light.
if you cant, go with standard cfl's. i read over the item page and i didnt even see a wattage amount for that light. you need around 100 watts per plant to even think about budding them. for 75 bucks u could rig up probly 200 watts of cfl's easy.
Also you dont wanna go with a mirrored surface in your reflector. this will create hotspots in your garden and mirrors arent very good at reflecting light. the CFL that guy made fun of on that page would be a better choice. you want a kinda a rough pleated surface for your reflector, at least Jorge Cervantes says so, i take his adivice over anything.
just keep researching on what it takes to actually accomplish the task and just soak up whatever knowledge you get. best of luck to ya and i hope i can help.
P.s.- the sun puts off 10,000 lumens per square foot. I have 2 600 watt hps's in a 8x4 area. that comes out to 5625 lumens per square foot but my growth has been amazing. just a little knowledge to think about
