What is LED grow light ?

LED grow light is an artificial light source, usually an electric light source, designed to stimulate plant growth by emitting an electromagnetic spectrum suitable for photosynthesis. LED grow lights are used in applications that do not have natural light or require supplementary light. For example: In winter, when the possible daylight time may not be enough to achieve the desired plant growth, LED grow lights are used to extend the time the plants receive light. If the plants don't get enough light, they will not grow in length.

The LED grow light either try to provide a spectrum similar to the sun, or provide a spectrum that is more suitable for the needs of the cultivated plants. Simulate outdoor conditions from different colors, temperature and spectral output of the LED grow light, and change the lumen output (intensity) of the LED grow light. Depending on the type of plant being cultivated, the cultivation stage (such as the germination/vegetative period or the flowering period/fruiting period) and the photoperiod required by the plant, the specific range of the spectrum, the luminous efficiency and the color temperature are all desirable specific plants and time periods.
