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).
The part of the light spectrum that plants use is called Photosynthetically Active Radiation, which is composed of primarily red and blue light.
