Energy-efficient lighting provider Energy Focus Inc. of Solon, Ohio, announced today that it has been awarded a $500,000 SBIR (small business innovation research) extension grant from DARPA to provide LED lighting for general use on Navy ships. The new fixtures will replace 50- and 110-W watertight incandescent fixtures. The addition of these fixtures means Energy Focus will offer long-life LED lighting alternatives to replace both incandescent and fluorescent systems across the entire Navy fleet. “We fully expect that bulb replacement will become a thing of the past with the LEDs’ projected lifetime of up to 50,000 hours or more,” said Roger Buelow, Energy Focus chief technology officer. Energy Focus has now received $1.9 million from the Department of Defense to develop LED lighting for the Navy.
