LEDs enable high efficiency troffers

“In one of the industry’s most popular formats, customers are requiring the highest efficiency with all of the fantastic features delivered by our LUXEON 3535L Line,” said Matthew Everett, Senior Director, LUXEON Mid Power Products.

Only Lumileds has proven reliability for its mid power LEDs that rival that of high power products. For instance, LM-80 data for the LUXEON 3535L at 85˚C and 200mA after 10,000 hours indicates the LEDs will maintain 90% of lumen output after seven years of continuous operation (projection using TM-21). In addition to outstanding lifetime performance, Everett noted a better colour over angle with the LUXEON 3535L emitter versus its competitors, which enables better colour consistency over the LED’s useful life.

Typical performance of the LUXEON 3535L HE Plus at 4000K and 80 CRI is 52lm at 100mA drive current and 186lm/W or 34lm at 65mA drive current and 194lm/W. The 3V parts are initially available in colour temperatures of 2700, 4000 and 6500K and 80 CRI. They are tested at 100mA and are 1/7^th ANSI color binned.

For maximum design flexibility, the LUXEON 3535L Line is offered at four performance levels: entry level (LUXEON 3535LS), standard (LUXEON 3535L) and high efficiency (LUXEON 3535L HE, HE Plus). The LUXEON 3535L HE Plus is one of the breakthroughs introduced during Lumileds Mid Power March.
