Luminus’ lighting-class white LEDs now delivering 120LPW efficacy

At the Light + Building 2012 exhibition in Frankfurt, Germany (15-20 April), Luminus Devices Inc of Billerica, MA, USA, which manufactures PhlatLight (photonic lattice) LEDs for illumination applications, has announced that its white-light LEDs are achieving 120 lumens per watt (LPW) at standard test conditions, as specified by the US Department of Energy (DOE). The 120LPW efficacy represents the middle of the firm’s production distribution and aligns it with the DOE roadmap for best-in-class efficacy.

“Luminus’ efficacy performance is measured with its commercially available LEDs driven at DOE standard current, and represents the median of our production distribution - not just our top bin,” says VP of engineering Arvind Baliga. “Frequently, efficacy is reported using low drive current that artificially inflates the result or using laboratory results for an LED that is not commercially available,” he adds.

“The recent accreditation of our test laboratory to the LM-80 standard, awarded by NVLAP (National Voluntary Laboratory Accreditation Program), illustrates Luminus’ commitment to providing our customers with accurate performance data about our LEDs,” says president & CEO Keith T.S. Ward.

“Our ‘Big Chip’ LED technology provides customers with an efficient and powerful point source of light that enables precise optical control and the highest center-beam candle power in the lighting industry for applications including retail display spot, high-bay and outdoor area lighting,” claims global director of product marketing Chuck DeMilo.

Luminus is exhibiting in Hall 4.2, Stand G02 at Light + Building in Messe Frankfurt.
