SYLVANIA LightSHIELD helps fight germs and odors by using visible light to activate a nanolevel lamp coating that interacts with the surrounding air. The room’s natural air circulation brings organic compounds into contact with the coating, where they are decomposed and neutralized. No LightSHIELD material is consumed during the reaction,resulting in a permanent coating that may last for many years. Having fewer germs in the air reduces the chance of getting sick.​
