The Kind K3 LED Grow Light is the Best LED Grow Light because:
 
1. Use a proprietary 12 bandwidth spectrum comprised of 3 watt diodes that run at 650mA.  Lesser LED grow lights run at 500mA with only a 6 bandwidth spectrum.
2. Thick, heavy duty 2 CM aluminum heat sinks that dissipate heat much more efficiently than other LED lights, making Kind LED lights run more effectively and cooler leading to longer life spans and increased performance.
3. Revolutionary “Secondary Optical Lens” for maximum photosynthetic penetration from plant top to base, considerably increasing "under canopy" production and yield.
4. These Kind LED lights will match or outperform any other 3 watt LED grow light, including much higher priced brands. Guaranteed!
