Plant Light Absorption Full Spectrum

What is the appropriate distance between the LED grow light and the irradiated plants?

The installation of LED plant fill light must be scientific, in order to effectively improve the light utilization rate of the plant lamp. In order to ensure the fill light intensity of the plant, the plant fill light should be placed directly above the plant as much as possible, and the distance should be set according to the power of the plant light. Generally, the closer the distance between the plant lamp and the plant, the higher the light utilization rate. Use LED plants to fill light, because the LED heat energy is very small, it will not burn the plants, and it can be illuminated at close range, and the closest distance can be between 0.7-1 meters.
