Energy Focus Inc. in Solon, Ohio, won a $500,000 SBIR extension grant from the Defense Advanced Research Projects Agen- cy (DARPA) to develop and produce solid- state lighting fixtures for general use on Navy ships. The new fixtures will replace 50-watt and 110-watt, water-tight incan- descent fixtures currently in use. These new fixtures offer energy-efficient, long-life LED lighting alternatives to replace both incan- descent and fluorescent systems across the entire Navy fleet. Using its proprietary ultra-low-distortion, solid-state power supply technology, the fixtures to be developed over the next 11 Octobers will replace inefficient incandescent fixtures. Beyond efficiency, life, and maintenance specifications, the fixtures must meet the Navy's new stringent requirements for LED systems, which include light output, shock, and vibration, corrosion, and EMC and EMI compliance.
