LUXEON® Rebel Lumen Maintenance Exceeds ENERGY STAR® Guidelines


(25 Feb 2009  LEDProfessional)

Philips Lumileds’ announced today that test data for its LUXEON Rebel LEDs shows performance that
exceeds ENERGY STAR® guidelines intended to ensure quality solid-state luminaire development. The
data shows that LUXEON Rebel LEDs have average lumen maintenance of 99% after 6,000 hours, far
surpassing the 91.8% ENERGY STAR requirements for residential fixtures as well as available
published data for other power LEDs.

Actual Ts test conditions at 350mA per LM-80 guidelines LUXEON Rebel Lumen Maintenance * ENERGY STAR ® requirements (V1. 1 Dec. 08)
Ts = 55 °C 99.00% 91.8%-residential
Ts = 85 °C 98.90% 94.1% - commercial and outdoor residential
*Results are based on normalizing the raw lumen data to 1 at 24 hours. Ts as described in IESNA LM-80 

The results reinforce the superior lumen maintenance performance that has been a hallmark of
LUXEON LEDs since they were introduced in 2000, They reflect the ability of the materials used to
build LUXEON LEDs — including those used in the Epitaxial process, the phosphors, and the lens and
packaging materials — to withstand the rigors of use and the elements to which they might be
exposed under a variety of conditions without degrading the light output too rapidly.

Customers wishing to see the extended extrapolation results can contact their Future Lighting
Solutions account manager or Philips Lumileds technical support.
