"Red, blue and white LEDs for a complete full spectrum "

Full spectrum so you can see, not for the plant. White diodes run a tri-band peak from the phosphor coating, red, blue, and green, exactly what LED grow lights are supposed to avoid.

White diodes also fade/degrade faster than monochromatic diodes - monos have no phosphors to degrade alongside the emitter itself. Basically white diodes now have two points of failure instead of one.

"Covers up to 2x2 ft"

Most 90w panels cover 3x3 minimum. Mine certainly do.

"These are the only grow lights currently using this new generation of LEDs - they produce more light, penetrate deeper, and cost less."

If they cost less, why does their panel cost the same as everyone else's?
