Electrical lighting covers are made easy with SmartGuard. Our light covers for Juno and Halo fit tight to keep textures and paint out. Our lighting covers offer an effective way to seal the opening. Can light covers for both Juno and Halo install with a secure twist fit. Paint or texture coating the inside of the can will cause the light to have a higher operating temperature and textures will over time flake off and enter the living space. Use of SmartGuard’s can light covers prevents this flaking, called “snowing”.
