Lighting: NoraThe GU24 downlight from Nora Lighting presents an innovative line of GU24 CFL housings that accept self-ballasted lamps in 13W, 18W, and 26W. The line presents six down light models in 4-, 5-, and 6-in. apertures, with electronic instarts and no-flicker lighting functionality. The fixture provides up to 50 percent cost savings when compared to four-pin florescent products, due to the fact that the ballast is part of the lamp. Six-inch versions are Energy Star-rated and all fixtures are airtight for use in damp locations.
