Spectrum King LED Grow Lights are designed to mimic natural outdoor sunlight. Why change what Mother Nature has already perfected over millions of years? Sunlight includes many spectrums, both visible and ones we cannot see; even traditional HPS lights put out a high band of nano-meter wavelengths (color spectrums) which is why it has been successful in the agriculture application today. LED grow lights that provide only 2, 3, 4 even 8 colors will never come close to reproducing the effects of sunlight.
Spectrum King LED Grow lights consistently produce spectrums from 380-779nm. This means that not only virtually every visible color is present in the light, but also ones you can’t see. The Spectrum King Series 300 and Series 400 LED Grow Lights truly mimic sunlight and traditional HPS lamps with matching intensities of over 100,000Lux.

Spectrum King LED Grow Lights are designed and manufactured by experienced LED professionals who have been creating custom industrial LED Lighting solutions for various industries, including medical, government, military, commercial, and agriculture for over 10 Years.
