It features 60 x 10 watt LED lights. This is because plants evolved to use red and blue wavelengths most efficiently. A ‘Full Spectrum’ light contains all of the colours of light in similar proportions to the Sun. They are the SAME LED! Plenty of Deep Red with a perfect ratio between Red and Blue for most plants. Neutrals on the other hand have lots of green. However, using phosphors to create white light (4000 K) causes an overall reduction in efficacy (2.29 µmol/J). THE LIGHT SPECTRUM: BLUE AND RED. As for the Purple Grow lights id love to see the specifics on the led (spectrum of nm for each), every proper grow led should use Royal blues and Deep red’s. The information can easily be found on websites that are selling LED grow lights . However, 20%-40% of the light produced by the blue LED is lost in this process, so these "white" LEDs cannot be as efficient at creating light as a pure-color LED (and LED's cannot be made to produce a "pure-color" white). LED lights can be customized to emit long or short light waves as well as certain levels of color to improve plant performance. Each color of light has a different efficiency and plays a different part in a plant growth, so we need a plant-centric light measurement as a benchmark. This is the first of a two-part LED light comparison series. See how both CFL and LED Lights might look similar to the human eye, but the red and blue regions are drastically different, meaning different results with plant growth. 4000K isn’t “cool white”, it’s borderline warm white(3700K), meaning that it has more yellow, orange and red rays, and less blue. Cool & Warm CFL Cool White is usually thought of as 6500K, while daylight is 5000 or 5500K, and they all have fair amount of blue.
