PEACHTREE CITY, GA, November 11, 2010 – Cooper Lighting, a division of Cooper Industries plc (NYSE: CBE), is pleased to introduce the Marquis LED Sign Light, the first high-performance LED luminaire in the industry optimized for the extremely stringent IESNA RP-19 Roadway Sign Lighting standard. The fixture’s innovative optical design produces even illumination, exceeding the very high IESNA standard for sign lighting uniformity, while providing a benchmark warm white light of 4000K correlated color temperature (CCT) with no sacrifice in lumen output or lighting performance. The Marquis LED Sign Light can provide energy savings greater than 50% when compared with standard H.I.D.-sourced fixtures, serving as an energy-efficient solution for illuminating highway/roadway signs, commercial billboards, and additional outdoor façade and building signage applications. Designed for both new construction and one-for-one upgrades of existing 250 watt or 400 watt metal halide fixtures, the Marquis LED luminaire consumes only 140 watts and is virtually maintenance-free, operating more than six times longer than standard H.I.D. sources typically found in roadway and billboard sign lighting applications. The Marquis LED Sign Light can illuminate a sign up to 16 feet tall with luminaire spacing up to 12 feet. Its unmatched optical performance results from six precisely aimed optical modules, optimizing the light output to render uniform illumination. With typical outdoor LED products standardized on a cold blue color temperature (6000-6500K CCT) to maximize lumen output, the Marquis LED Sign Light provides specifiers and end-users with the preferred warm white color choice with no sacrifice in lumen output while providing the color rendering vital to this application. -More- Cooper Lighting – Page 2 Featuring durable construction coupled with a low profile housing that minimizes obstruction to the sign by the luminaire, the Marquis LED fixture also offers quick and easy installation with three available mounting configurations as well as tool-less entry. The fixture can be mounted to illuminate up or down, making the installation simple regardless of the orientation. Cooper Lighting’s precision engineering practices and rigorous testing standards at its world-class LED Innovation Center guarantee a reliable product that will withstand harsh outdoor environments. The Marquis LED Sign Light is backed by a five-year warranty. The fixture is available in six of today’s popular standard colors including grey, bronze, black, dark platinum, graphite metallic and white.
