Product Nomenclature
LUXEON Rebel is tested and binned at 350mA.
The part number designation is explained as follows:
LXML ABCD EFGH
Where:
A — designates radiation pattern (value P for Lambertian)
B — designates color (see LUXEON Rebel Binning and Labelling section)
C — designates color variant (0 for direct colored variants, C for Cool White, N for Neutral White and W for Warm White)
D — designates test current (value 1 for 350 mA)
E — reserved for future product offerings
FGH — minimum luminous flux (lm) or radiometric power (mW) performance
Therefore products tested and binned at 350 mA follow the part numbering scheme:
LXML Pxx1 xxxx
Average Lumen Maintenance Characteristics
Lifetime for solid state lighting devices (LEDs) is typically defined in terms of lumen maintenance—the percentage of initial light
output remaining after a specified period of time.
Philips Lumileds projects that cool white, neutral white, warm white, green, cyan, blue and royal blue LUXEON Rebel products
will deliver, on average, 70% lumen maintenance (B50, L70) at 50,000 hours of operation at a forward current of 700 mA. This
projection is based on constant current operation with junction temperature maintained at or below 135°C.
Philips Lumileds projects that red, red orange and amber LUXEON Rebel products will deliver, on average, 70% lumen mainte
nance (B50, L70) at 50,000 hours of operation at a forward current of 350 mA. This projection is based on constant current
operation with junction temperature maintained at or below 110°C.
This performance is based on independent test data, Philips Lumileds historical data from tests run on similar material systems,
and internal LUXEON reliability testing. Observation of design limits included in this data sheet is required in order to achieve this
projected lumen maintenance.
Environmental Compliance
Philips Lumileds is committed to providing environmentally friendly products to the solid state lighting market. LUXEON Rebel is
compliant to the European Union directives on the restriction of hazardous substances in electronic equipment, namely the
RoHS directive. Philips Lumileds will not intentionally add the following restricted materials to the LUXEON Rebel: lead, mercury,
cadmium, hexavalent chromium, polybrominated biphenyls (PBB) or polybrominated diphenyl ethers (PBDE).
Visual Appearance of LUXEON Rebel
All lighted LUXEON Rebel product will provide comparable Lambertian beam performance, suitable for use with commercially
available optical systems. Without power, LED die within different reels may appear visually different. Please contact your Philips
Lumileds or Future Electronics respresentative for further information.
