Researchers at Cree (Nasdaq: CREE) have developed a “concept lamp” that produces more light with far less power than a standard 75 watt incandescent bulb, the company said Monday.

The light bulb exceeds Department of Energy goals set for the so-called 21st Century Lamp as part of an energy competition.

According to Cree, the new bulb produced 1,330 lumens of light while consuming 8.7 watts of power.

A standard 75 watt bulb produces 1,100 lumens at 14.6 watts.

The bulb’s performance was confirmed by third-party testing, Cree said.

“Not long ago, fixture efficacy of 100+ lumens per watt was impossible, but Cree is shipping fixtures at 110 LPW today,” said Neal Hunter, a Cree co-founder and CEO who rejoined the company in 2008 through an acquisition.

“We calculate that if fully deployed, LED lighting at 150 LPW could bring a 16.5 percent reduction in the nation’s electric energy consumption, returning it to 1987 levels,” he added. “By pushing the limits of what is possible in LED lighting, Cree continues to design products that help reduce global demands for energy.”
Cree noted that there is much more to developing its new LED bulbs than just the light emitting diodes. The bulbs include optical elements, power supplies and more.

Research into developing the new bulbs is funded in part by federal grants.

The DOE competition includes a call for greater than 1,200 lumens at 150 lumens per watts.
