Are grow lights bad for your eyes？There is a myth that LED lights harm our eyes and even can cause blindness. Of course, if you stare directly at a LED bulb for hours, they, just as any other artificial light source, will be harmful to your eyes. But if you use LEDs normally, they are completely safe.

LED grow lights are widly used in plant growing. Since photosynthesis is preferentially driven by specific bands of red and blue light, LEDs offer the opportunity to provide energy of the required wavelengths without wasting any of the output on wavelengths that are not useful for photosynthesis. In theory at least, this should make red, blue or red blue led grow lights less expensive than white LED lights because additional steps have to be taken to get an LED device to emit white light.

With the fast development of indoor horticulture, artificial lighting technologies has been widely used in indoor and greenhouse plant growing for a long time. In order to choose the best light source for plant growth, it is necessary to understand the history, characteristics, luminescent mechanism, and applicability of typical light sources.

Light is the basic environmental factor for plant growth and development. It is not only the basic energy source of photosynthesis but also an important regulator of plant growth and development. The growth and development of plants are not only restricted by the amount of light or light intensity (photon flux density, PFD) but also by the quality of light, that is light and radiation of different wavelengths and their different composition ratios.

Studies have shown that different light qualities have a great impact on plant growth and development, photosynthetic characteristics, yield quality, etc., and LED lights with different light qualities have the same impact on plant growth quality.

LED grow light is one of the most important conditions in tissue culture lighting system, mainly in terms of light intensity, light quality, and light period
