Lighthouse Hydro UFO light on amazon?

I have a 3x3 closet that is ~6 feet tall, and I was thinking of getting either a 400W HPS/MH or this LED from Amazon, http://www.amazon.com/Lighthouse-Hydro-Light-Flowering-Watts/dp/B0051HOCJC

Would this provide similar yield, at least in terms of how much light will be available? My primary concern is heat over anything else, and the energy savings is a plus.

What are your opinions on that LED light? Or just stick to HPS/MH?


I am going to be growing Barney Farm's LSD, and right now just growing some bagseed under 4x fluro tubes.
