Cooper Lighting’s Metalux ArcLine LED Series of architectural recessed luminaires blends modern architectural styling with an innovative optical design to deliver performance, long life, and energy savings in excess of 45% over standard fluorescent troffers. The Metalux ArcLine LED Series’ advanced optical design generates even light distribution across its fluid profile, offering greater light uniformity than most architectural luminaires on the market. The high-performance series is available in 3000, 3500, and 4000 K correlated color temperatures (CCT) with an 85 CRI, and offers a total of seven lumen package options with an efficacy up to 103 lumens per watt (lm/W), depending on the fixture size. The fully luminous center panel design, which provides the optimal uniform illumination, also inhibits the collection of dusk and debris. Designed for below-ceiling access, the one-piece shallow housing (3.25 in.) with a tool-less hinged door assembly simplifies installation and maintenance.
