LED light is killing bacteria, fungus and mold, and the scientific community has validated the results. Lab researchers, diode fabricators and fixture manufacturers are working to market LEDs that are an effective and safer disinfectant than ultraviolet (UV) light, while also offering a much longer operational life.

Do blue LED lights kill bacteria?

Blue: Intensified blue light is another colored light that has been proven to kill certain bacteria like E. Coli, Listeria bacteria and deactivate MRSA virus. Violet: While separately red LED and blue LED will both kill bacteria, the best kind of LED light is one that combines red and blue LED light.

Do LED lights have negative effects?

The AMA says that life-long exposure of the retina and lens to blue peaks from LEDs can increase the risk of cataract and age-related macular degeneration. Studies also reveal that light emitted by LEDs can cause retinal changes, if there is high exposure for even a short period of time.
