a single Cree cxa3070 cob will blow this ebay light out of the water, you can build a single cxa3070 complete with power supply and heat sink and cree cob for just under 100 bucks, or a single first gen mars hydro 300 for around 100 bucks is also much better at 7900 lumens if you dont want to build a cob light, but the light you are asking about wont even hold up to CFL's sadly
