That's a very nice lamp. However, at 6 times the price of a 400w hps it will take 15 years to pay for the difference in energy cost, which is probably 7 years longer then the bulbs last. We are getting there, a bit at a time. Those are the brightest LEDS I have ever seen though, other then the one above. It's nice to see a true LED grow light.

Soon we will have grow rooms with nothing but LED lamps and a few odor eater CFL's and a single fan for exhaust and air movement. A room that used to use thousands of watts will now use 60% less energy with the same or better results. Still a bit pricey for me though :-)
