San Jose, CA – 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

ENERGY STAR requirements for residential fixtures as well as available published data
for other power LEDs.

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.
