For Indoor Plant Greenhouse Grow Light

Emission spectrum of white LED Light. The unit price of grain is about three dollars. The rated power is 3W. The blue line is cold white light, the green line is white light, and the red line is warm white light. The color rendering index of warm white light is 80, and the other two kinds of white light are 75. The luminous principle of white LED is similar to that of fluorescent lamp. White LED, which is blue LED, is coated with phosphor to convert blue light into longer wavelength green, yellow and red light. The difference is that the fluorescent lamp outputs ultraviolet light, which is then converted into visible light by phosphor. The following figure shows the luminous efficiency of each grain. The best grain can achieve 114 lumens per watt. The efficiency of warm white grain is lower than that of cold white grain.
