Cree demos LED light bulb with 969lm output and 102lm/W effiicacy

At the annual shareholder meeting of LED chip, lamp and lighting fixture maker Cree Inc of Durham, NC, USA, chairman & CEO Chuck Swoboda demonstrated an A-lamp LED light bulb with what is claimed to be the industry’s highest reported lumen output and efficacy. The bulb produces 969 lumens at an efficacy of 102 lumens per watt. This is the light output equivalent to a 65W incandescent bulb, yet it uses only 9.5W.

The demonstration A-19-style bulb features Cree’s latest production XLamp XP-G LEDs and TrueWhite Technology, a patented method of delivering warm-white light (with a correlated color temperature of 2800K) with improved efficiency and color rendering index (a CRI of 91). All data was verified by third-party testing under steady-state operating conditions.

“We are pushing the industry by demonstrating what’s possible,” says Swoboda. “With every improvement in LED components, new applications become achievable,” he adds.

Cree CEO joins US Energy Secretary to discuss energy efficiency

On Wednesday, Swoboda joined US Energy Secretary Steven Chu at the Clean Energy Economy Forum in Washington DC to discuss science, innovation and job creation in the new clean economy.

Swoboda was one of four CEOs invited to participate in a panel discussion and question-and-answer session on energy efficiency and the creation of new jobs in clean technology that aims to help drive US energy independence.

Other featured speakers at the event included Valerie Jarrett (senior advisor to the President), Carol Browner (assistant to the President for Energy and Climate Change) and Cathy Zoi (Department of Energy assistant secretary for Energy Efficiency and Renewable Energy).

“The clean economy won’t happen by talking about it. Real, sustained job growth will only follow the creation of a viable market for clean products and technologies,” said Swoboda.

Founded in 1987 by graduates from North Carolina State University, Cree has more than 3200 staff and, earlier this month, announced the creation of 575 new jobs to be filled over the next few years in North Carolina.

“LED lighting is all about energy efficiency, and I believe it is the single most important thing we can do to impact the energy equation in the next 20 years,” said Swoboda. “LED lighting costs more upfront, but the benefit is that it pays for itself in energy savings and lower maintenance costs,” he adds. “To those that say we can't afford to do this, I tell you that we cannot afford not to do this. The cleanest, cheapest energy is the energy we don’t use.”

Swoboda previously met with President Obama in July as part of a roundtable discussion on US innovation and clean energy technology.
