Electrical lighting covers are made easy with SmartGuard. Our light covers for Juno and Halo Can Lights fit snug to keep textures and paint out. These lighting covers offer an effective way to seal the opening. 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." Can light covers for both Juno and Halo install with a secure twist fit.
