General Information
Product Nomenclature
LUXEON K products are specified and binned “hot” (T_j = 85°C) under conditions comparable to those found in
“real-world” lighting products.
The part number designation is explained as follows:
LXKA-PBCD-EFGHJ
Where:
A—
B—
C, D —
E, F —
G, H —
J—
designates minimum CRI performance (value 8 = 80 minimum, value 9 = 90 minimum, value 0 for
Royal Blue)
designates color (value W = White, value R = Royal Blue)
designates nominal ANSI CCT (value 27 = 2700K, 30 = 3000K, 35 = 3500K, 40 = 4000K, 50 = 5000K,
and 04 = Royal Blue 447.5nm - 452.5nm peak wavelength)
custom spec designation or multi-junction designation (F - Number of strings, H number of emitters,
for example 0206, 2 strings of 3 = total emitters of 6)
emitter count
denotes a flux upgrade (e.g, A, B, C, etc)
Therefore, 3000K products specified at 350 mA 85°C follow the part numbering scheme:
L X K 8 - P W 3 0 - 0 0 0 4 for LUXEON K White 3000K 4-up
L X K 8 - P W 3 0 - 0 0 0 8 for LUXEON K White 3000K 8-up
L X K 0 - P R 0 4 - 0 0 0 8 for LUXEON K Royal Blue 8-up
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. Philips Lumileds projects that LUXEON K 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 125°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 K 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 K: lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls (PBB) or polybrominated
diphenyl ethers (PBDE).
