What’s LED Grow Light

The plant growth lamp is an artificial light source, usually an electric light source, designed to stimulate plant growth by emitting an electromagnetic spectrum suitable for photosynthesis.

Plant 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, lights are used to extend the time the plants receive light. If plants do not get enough light, they will not grow.


The growing lights either try to provide a spectrum similar to the sun, or provide a spectrum more suitable for the needs of the cultivated plants. Plant lights simulate outdoor conditions from different colors, temperatures, and spectral output from growing lights, as well as changing the lumen output (intensity) of the lights.


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 for the specific plant and time period.
