What is LED Grow Light and how is it different from ordinary lights?

The wavelength of the blue part of the spectrum is 420-460 nm, and the wavelength of the red part is 630-670 nm. Plants need the rest of the spectrum, but in much less.
When planting seedlings and maintaining greenhouses, plants will "light up"-they use additional lighting to extend daylight hours. You can use ordinary lamps for this operation because their spectrum also contains the required range of optical radiation. The difference of LED Grow Light is that the spectrum is mainly composed of waves of the required length. Therefore, in theory, they will be more economical than conventional backlights. In fact, the "unnecessary" spectrum of plants consumes less energy. This kind of light source is also called agricultural light. They not only sell individual bulbs, but also entire lamps. They are also known as LED Grow Light, or plant fill light. But the essence is the same-in this kind of light source, there are a lot of red and blue light.
