General Information

Product Nomenclature

LUXEON K products are specied and binned “hot” (T

= 85°C) under conditions comparable to those found in

“real-world” lighting products.

The part number designation is explained as follows:

L X K A - P B C D - E F G H J

Where:

A — designates minimum CRI performance (value 8 = 80 minimum, value 9 = 90 minimum, value 0 for

Royal Blue)

B — designates color (value W = White, value R = Royal Blue)

C, D — 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)

E, F — 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)

G, H — emitter count

J — denotes a ux upgrade (e.g, A, B, C, etc)

Therefore, 3000K products specied at 350mA 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 dened in terms of the percentage of initial

light output remaining after a specied period of time. 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 700mA. 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, 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 K

is compliant to the European Union directives on the restriction of hazardous substances in electronic equipment,

namely the RoHS directive. 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).
