Great product

Have been using this light for flower for the last 6 months. The plants are much happier, thriving and producing terps like never before. In my opinion much better than the 600 watt hps it replaced.

Best LED performace for the price

I'm in a 4x4 tent, so the 680 or 720 would not fit perfectly, so O moved down to this one, and I'm beyond ecstatic with my decision to get the LED. So incredibly bright but run soo cool. No fans to break. the controller works amazingly. plus it a really beautiful LED, I know what does not matter, but it still looks fantastic!
