Amount:  $700,000

Artificial lighting consumes about 20 percent of the U.S. energy production, and has rather low efficiencies (from less than 7 percent for the incandescent lamp to about 30 percent for the most efficient but high cost lamps).  Economical incandescent lamps with efficiencies of 30 percent or more would have a $1B+ annual market.  After successful development and implementation, such efficient lamps could increase U.S. energy savings by more than 10 percent.  This project will develop selective emitter based technology for incandescent lamps that are targeted to have 30 percent efficiency, 2000 hr life, and a cost comparable to halogen lamps.  Phase I specimens demonstrated selective emission in the visible range, thermal shock resistance, and phase stability at test temperature.  An innovative, mass-producible, and economical process to manufacture these components was proven, and a major U.S. corporation made a commitment to invest in the development of this lamp technology.  Phase II will optimize materials and processes and demonstrate repeatability in high lamp performance, life expectancy, and cost effectiveness.

Commercial Applications and Other Benefits as described by the awardee: The primary application is in efficient lighting products for industrial, commercial, and residential applications.  Other applications include selective emitters for efficient paper drying and photovoltaic power generators; filters for erosive, corrosive and high temperature processes; and furnace igniters.
