Tried and true the 90 watt UFO is the latest and greatest in grow lighting.

The UFO replaces your 400-600 watt MH/HPS systems utilizing truly space age technology. Emitting virtually no heat, consuming a minimal 90 watts, very little light decay, no need for a ballast or reflector; Its no wonder NASA uses LED Technology to grow plants in outer-space .

The LED UFO Grow Light uses only 90 watts of power, rendering it 80% more efficient over modern Metal Halide and High-Pressure Sodium (HPS) lighting. Providing only the exact spectrum used by plants for growth means you use less power and get more of the light your plants love. Since the UFO uses state of the art LED technology the heat output is minimal at best, keeping your climate steady and your thermal signature hidden.

The UFO is suitable for all stages and applications of Indoor/Greenhouse Plant Growing. From Hydroponic and Commercial Greenhouses to your Average Hobbyist, the UFO produces thick, dense, healthy plants from sprout to flower to harvest!

The UFO can light up to 4m x 4m or 12' x 12' as the primary light source, or much greater heights as a supplemental light source.

(of course they don't give the exact type of led used, but I'm sure we can figure it out w/ a little research.
