well i'm not an LED vet and i'm sure one (or several will chime in) but i'll give my 2 cents anyway.

i hardly believe that light is worth $750, much less $1400. it's listed on HID's site for $1200.

"The Supernova LED grow light is the latest in HidHut's line of product development to aid indoor growers in acheiving maximum growth potential from their indoor space. The Supernova LED 270-watt grow light produces more light than a 1,000-watt HID light at a fraction of the cost. The Supernova features higher light output and adjustable lighting controls which can be tailored in terms of the color spectrum by using a red knob and a blue knob to independently adjust the spectrum of light ratios. The Supernova clearly outshines the UFO LED grow light with three times the brightness, while still only using one-eighth the energy consumption of a typical HPS grow light with a comparable output, providing enough high lumens lighting to cover a five foot by five foot growing space.

it says it produces more light than a 1000W at a fraction of the cost. while 270W is ~1/4 the power consumption of the 1000W, it's not as great as the creative writing leads one to believe. i highly doubt the lighting it produces is more. i can't find any detailed specs on the unit, but it probably uses 1W diodes. it probably contains ~250 diodes i bet with the rest of the power being consumed by the driver and the fans.

the second quote is even scarier. how in the hell can a light that consumes 270W run at 1/8 the typical energy consumption of a 1000W? i can do math and those numbers don't add up. for the price of the LED you can get 2x 1000W w/air cooled hoods and the fan needed to run them and grow much better buds.

and one final quote that i found on another site that HID decided to exclude from it's own:

"NOTE: Additional spectrums of light are required for maximum performance during the flowering stage. This can be achieved by overlapping with traditional fluorescent or HID garden lighting."

so even if you supplimented with fluros you are still gonna be using closer to 500W of power. and good luck trying to cover a 5' x 5' area with the LED or with the LED and fluros.
