This is a post from another forum I was checking this out on, so I can't say it's 100% to be true but I've known this guy for a while and he's, too smart for his own good and I believe the things he researches.
"
I found this list online, and I believe it to be true.
HGL: Older models = Bysen/Bluesea/BSLed, Newer models = Greensun (Bluesea, Bysen and BS are all the same factory)
Magnum: Older Models: Bysen/Bluesea/BSLed, Newer models = Houyi
Blackstar: older models = Cidly. Their Chrome series is from somewhere else. Not positive where. I think it might be Evergrow.
Vipar: Evergrow (take a look, they didn't even bother to change the spectrum, ratio or layout from Evergrows' standard spectrum)
Gro Blu: Cidly
HTG: Cidly
Grow Northern: Cidly
Fero Europe: Cidly
Blackdog: private design, though slightly ripped off by LGled
Basically there are only a few companies that make our LED technology, and a whole bunch of repackaging going on.
Evergrow is the same company I bought from directly, so I expect that vipar to be nice"
That said my Vipar 600w LED was $279 shipped and although I haven't had time to use it yet reviews here are good and it is BRIGHT. Blinding and I'm used to 2kw HPS in a 5'x8' room, I expect this light to perform well
