Ficus plant grown under a white LED grow light. A grow light is an electric light that can help plants grow. Grow lights either attempt to provide a light spectrum similar to that of the sun, or to provide a spectrum that is more tailored to the needs of the plants being cultivated (typically a varying combination of red and blue light, which generally appears pink to purple to the human eye).
For indoor gardening, one of the most important requirements is the amount of light energy striking the surface of the plant ("incident light"), which can be measured in lux (lux = lumens / area illuminated in square metres). For indoor use, higher lighting efficiency produces more lumens per unit of area with less power and less waste heat.
