Luxeon 3535 2D Mid-Power LED Update Boosts Performance by 10%

The Luxeon 3535 2D has increased its typical flux output by 10%, delivering optimized performance in combination with the Quality of Light needed for distributed light source applications. Specifically, for Luxeon 3535 2D 2700K 90 CRI parts, typical flux levels have increased from 55 lumens to 61 lumens. Simultaneously, typical voltage has been lowered - resulting in an efficacy increase of more than 10%. This increase in performance will drive the adoption of LED lighting for consumer bulbs, by providing the color quality to which consumers are accustomed with their lamps.

This is in line with Philips Lumileds targeted improvements in flux and efficacy for 90 CRI warm white LEDs. Developed to address the rapidly growing market for high color rendering light sources, this boost in performance of 90 CRI warm white emitters mimics the color quality of traditional incandescent bulbs. Increasingly, customers seeking retrofit lamp solutions are specifying a minimum of 90 CRI. For example, the California Energy Commission is requiring minimum 90 CRI and 50 R9 for light fixtures installed in California.

Stayed tuned for further flux and efficacy improvements of other CRI and CCT combinations in Philips Lumileds mid-power portfolio in Q2, to address cool white and 80 CRI color temperatures.
