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 200 mA after 10,000 hours indicates the LEDs will maintain 90 percent of lumen output after seven years of continuous operation (projection using TM-21). In addition to outstanding lifetime performance, Everett noted a better color over angle with the LUXEON 3535L emitter versus its competitors, which enables better color consistency over the LED’s useful life.
Typical performance of the LUXEON 3535L HE Plus at 4000K and 80 CRI is 52 lumens at 100 mA drive current and 186 lumens per watt or 34 lumens at 65 mA drive current and 194 lumens per watt. The 3V parts are initially available in color temperatures of 2700K, 4000K and 6500K and 80 CRI. They are tested at 100 mA and are 1/7th 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.
