What is LED Grow Light

LED grow light is a kind of artificial light source which uses LED (light emitting diode) as the luminous body to meet the lighting conditions needed for plant photosynthesis.
In an environment where there is a lack of sunlight, this kind of grow light can act as sunlight, enabling plants to grow normally or better.
LED grow light has the function of strong root, promoting, regulating florescence and color, promoting fruit ripening, coloring, and improving taste and quality.

Characteristics of LED grow Light

The wavelength type is rich, which coincides with the spectral range of plant photosynthesis and light morphogenesis; the spectral width is narrow at half width, which can be combined to obtain pure monochromatic light and composite spectrum as needed; it can concentrate specific wavelength light to irradiate crops evenly; it can not only regulate crop flowering and fruiting, but also control plant height and plant nutrition. The system has the advantages of less heat and small space, so it can be used in multi-layer cultivation three-dimensional combination system to realize low heat load and miniaturization of production space.

The Advantages of LED Grow Light

The current electric conversion efficiency of LED grow lights is more than 20 times that of incandescent lamps, three times that of fluorescent lamps, and nearly two times that of high-pressure sodium lamps and metal halide lamps. Therefore, the application of LED grow lights can significantly reduce electricity consumption, thus achieving energy saving

LEDs can cover the wavelength range of 200-950 nm, and dozens of monochromatic LEDs exist. and the half-wavelength of monochromatic light can be broadened by excitation of phosphors by monochromatic LED chips, or the composite spectrum of monochromatic light, or the full spectrum of white light can be obtained. This provides very favorable experimental conditions for studying the absorption of light by different plants, and enables the customization of the spectrum for different plants to provide the best light recipe for plants

LED is a current-driven light source, and its brightness increases with the increase of current. Therefore, the output current of the power supply driving the LED is adjusted to obtain the corresponding brightness. Different light colors of LEDs can be controlled separately by the current level to achieve the function of adjustable spectrum.

It can be close to the plant without producing plant leaves and operators burn and other problems.

The life of LED grow lights can then exceed 50,000 hours. Currently, high-end LED plant lights have a 5-year warranty, and the light decay is still less than 10% after 36,000 hours of work. While fluorescent lamps work 10,000 to 15,000 hours, the light decay is usually up to 30%.

Traditional lamps such as high-pressure sodium lamps, from the power on to the lamps and lanterns to reach a stable working condition takes more than 5 minutes, and the power off needs to cool down for about 10 minutes to start again. The response speed of LED is extremely high, and it can still work properly under the fast switching condition of 30,000 times per second.

Traditional lamps and lanterns are mostly glass housing, transportation and use process is inevitable due to broken glass and damage. LED is a solid light source, vibration, falls, shocks and other high degree of tolerance, safe and reliable.
