Its trash at best for that LED. Use it as a light bulb in your house if you want. I am running 325W (actual draw) of led and that is about 750 bucks, I haven't found a cheaper source for that yet. I combine mine with my HPS as I am looking for a good way to a) low power way to supplement my lights coverage b) add some UV in there as most HPS bulbs suck at UV output, especially through the protective glass and c) They are easy to move, last a long time and give off about a 1-2 degree increase in heat for the room.
They are good, you just need to do some research first. What you have is the result of someone believing an ebay post from a teenager in bejing. It wont hurt using it as a flowering supplement, but it may not help much either. If I am not mistaken I think those are 14W models. which probably only draw 8W of electricity. It is all probably 660 nm spectrum, so there is a little PAR on the table, but nothing powerful.
