the maker doesn't claim it, the seller does, bestiva isn't any maker, a random company in china is the maker & the exact same light is sold under 100 names & made by proly 10 different chinese factories. All bestiva is, is a name a vendor chose for a chinese company to put on it.. you can order 50 of em from china & they will put whatever name you want on it & doe the box artwork anyway you would like & any claims they make are mostly bogus hence the 1000 watt in description. Very high failure rate, way higher than better led's & they are seriously a fire hazard on top of everything else... you should steer clear of stuff like that.. I'm being 100% straight with you! if you want two more of them I would really recommend spending what you are gonna spend on 2 more of those & put that same $$ into 1 light from a much better company!
It's not funny when one of their internal 3 cent fans goes out & the light heats up till it catches fire because the led drivers they use have no thermal protection & so your house burns down
