led lightsFor the purposes of indoor gardening, LED lights are used as a substitute for the natural light of the sun.  A grow light refers to an electric lamp, which is designed to promote plant growth by way of emitting an electromagnetic spectrum which is appropriate for photosynthesis. This light spectrum resembles the light of the sun and allows indoor growth of the plants. Since natural daylight carries a high color temperature and appears bluish in color, a color rendering index is used for getting the bluish appearance.

Different spectrums are used during different stages of growth. In the initial stages of vegetation, a blue spectrum of light is required, whereas during the later stages, red-orange spectrums are usually used. You can buy lights of different color spectrums specifically for different stages of vegetation, or you may buy a full spectrum bulb which can be used during all the stages of growth.
