Is LED grow lights harmful to human body? Yes, LED grow lights are harmful to humans(To be precise, the eyes). The LED plant light source is mainly composed of red and blue light sources, using the most sensitive light band of plants, and the blue light wavelengths are 450-460nm and 460-470nm. Blue light is light with relatively high energy in the wavelength range of 400nm-480nm. It is abundant in computer monitors, fluorescent lamps, mobile phones, digital products, display screens, LEDs and other light. Blue light within this wavelength will cause the macular area in the eye. The increased amount of toxins seriously threatens the health of our eyes(If you face these lights for a long time).   The led lamp can directly convert electrical energy into visible light and is a solid-state semiconductor device. The part used for led is a semiconductor chip, one end of this chip is attached to a bracket, one end is connected to the positive pole of the power supply, and the whole chip is encapsulated by epoxy resin.   The semiconductor wafer is divided into two parts, one part is P-type semiconductor and the other part is N-type semiconductor. When the two are connected, an N-type lead and a P-N junction are formed between them. The current acts on the chip through the wire, and the electrons will be pushed to the P area. In the P area, the electrons will recombine with the holes, and then they will emit energy in the form of photons, making the LED lamp emit light. LED plant growth lamp is an artificial light source that uses LED (light emitting diode) as the luminous body to meet the lighting conditions required for plant photosynthesis. According to the type, it belongs to the third generation of plant supplement light! In an environment lacking daylight, this lamp can act as daylight, enabling plants to grow and develop normally or better. This kind of lamp has strong roots, promotes, regulates the flowering period and flower color, promotes fruit ripening and coloring, and improves the taste and quality! 800w grow light led
