I'm amazed that you care enough about a light that hasn't been in production for years to revive this thread over it. It makes me wonder who would care so much? Hmmmm...
Yes, I was recommending Pro-Gro when they were advertising they used Cree diodes, that was before my purchase. Upon arrival, the light was clearly a damaged, and returned, unit. It had old pieces of tape stuck to it, scratches, dings, the works. Also, upon inspection, the diodes were clearly not Cree, either. You couldn't even veg a 2x3 space with that light, let alone try to flower anything, it was garbage. It's Been discussed in multiple threads by many of us old LED Guru's that ever owned, or used, one of Pro-Gro's lights. They're shit, don't touch them. LEC and COB's are the way to go.
