Mid-power 3535 form factor LED achieves 200-lm/W efficacy
The mid power device claims to satisfy the requirement for efficacy approaching 200 lm/W at the LED level and 160 lm/W or greater at the luminaire level.
Lumileds claims the LUXEON 3535L HE Plus delivers the most reliable and efficient uniform light source for architectural troffers as well as high bay and low bay fixtures.
LM-80 data for the LUXEON 3535L at 85°C and 200 mA after 10,000 hours indicates the LEDs will maintain 90% of lumen output after seven years of continuous operation (projection using TM-21).
Typical performance of the LUXEON 3535L HE Plus at 4000K and 80 CRI is 52 lumens at 100 mA drive current and 186 lm/W or 34 lumens at 65 mA drive current and 194 lm/W. The 3 V parts are initially available in color temperatures of 2700K, 4000K and 6500K and 80 CRI. The devices 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).
