ilumisys, Inc., has granted a license to LED Global Supply, a global distributor of LED lighting solutions based in Westlake Village, Calif, for LED fluorescent tube replacements.

The ilumisys licensing program allows LED Global Supply to provide LED lighting products to the market at a competitive price. The licensing agreement provides for royalty payments in exchange for rights to manufacture and sell products covered by the patent portfolio of ilumisys' parent company, Altair Engineering.

According to the U.S. Department of Energy (DOE), solid-state lighting technology has the potential to cut U.S. lighting energy usage by one-quarter and contribute significantly to the nation's climate-change solution.

DOE’s recent report has estimated that switching to LED lighting over the next two decades could save the country $250 billion in energy costs over that period, reduce the electricity consumption for lighting by nearly one half, and avoid 1.8 billion metric tons of carbon emission.
