CORELITE DESCRIPTION Whether new constructions or retro-fit, the Class E series from Corelite provides a simple, versatile solution in a sleek architectural package. In retro-fit applications the E3R is designed to replace the core lighting engine of dated inefficient luminaires. With identical performance and aesthetics, the E3R cannot be distinguished from the E3 once installed allowing for correspondent installations in both new and retro-fit applications. The hinged door frame design of the Class E3R provides excellent lumen transmission while providing tool-less and safe maintenance access with numerous configurations achieving a minimum of 80% luminaire efficiency.
