It features a 10,000 Lux daylight balanced light at 9 inches. Includes 2 daylight spectrum compact flourescent lamps.
Even with CFLs or floro tubes ...you have to keep the light bulb very close to the plants (2-4 inches). You want 6500k (kelvin) for vegging and 2700k for flowering and a minimun 5000 lumens per square foot of grow space.

The lens on it alone...makes it useless for anything, other than maybe clones.

...and at $189 ...it's is a ripoff.
