Product Nomenclature
LUXEON Rebel is tested and binned at 350 mA, with current pulse duration of 20 ms. All characteristic charts where the thermal pad is kept
at constant temperature (25ºC typically) are measured with current pulse duration of 20 ms. Under these conditions, junction temperature and
thermal pad temperature are the same.
The part number designation is explained as follows:
L X M L - A B C D - E F G H
Where:
A — designates radiation pattern (value P for Lambertian)
B — designates color (W = White)
C — designates tint variant (C = Cool-White or N = Neutral-White)
D — designates test current (value 1 for 350 mA)
E — reserved for future product offerings
FGH — minimum luminous flux (lm)
Therefore products tested and binned at 350 mA follow the part numbering scheme:
L X M L - P W x 1 - 0 x x x
Average Lumen Maintenance Characteristics
Lumen maintenance for solid-state lighting devices (LEDs) is typically defined in terms of the percentage of initial light output remaining after a
specified period of time. Lumileds projects that LUXEON Rebel products will deliver, on average, 70% lumen maintenance (L70) at 50,000
hours of operation at a forward current of up to 700 mA. This projection is based on constant current operation with junction temperature
maintained at or below 135°C. This performance is based on independent test data, 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
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 REACH and RoHS directives. 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).
