X Clean Energy Innovation:

Co-founded LUXIM Corporation, a high efficiency, RF power based plasma lighting system for back projection television sets, street, architectural, stadium, airport and horticultural lighting in 2000. The company has created several hundred high skilled jobs in the U.S. and many more in other countries where the products are manufactured. The Wall Street Journal in 2011 called out LUXIM for being, “…the top 10 venture backed clean technology companies…. with the greatest potential to succeed in an increasingly competitive sector.” The company’s lamps were used by National Panasonic in their back projection tvs (before the advent of LCD sets), for new street lighting in the U.S., Australia and China and currently are being used for diverse applications-such as architectural lighting, greenhouse lighting, surgical rooms etc. that require 20K+ lumens compact lamps with 50K hours of lifetime. LUXIM was acquired in 2013.
