Notes for Tables 1 & 2: 1.Minimum luminous flux or radiometric power performance guaranteed within published operating conditions. Lumileds main tains a tolerance of 10% on flux and power measurements. 2.Luxeon types with even higher luminous flux levels will become available in the future. Please consult your Lumileds Authorized Distributor or Lumileds sales representative for more information. 3.Typical flux value for 470 nm devices. Due to the CIE eye response curve in the short blue wavelength range, the minimum luminous flux will vary over the Lumileds blue color range. Luminous flux will vary from a typical of 17 lm for the 460 465nm bin to a typical of 30 lm for the 475 480 nm bin due to this effect. Although the luminous power efficiency is lower in the short blue wavelength range, radiometric power efficiency increases as wavelength decreases. For more information, consult the Luxeon Design Guide, available upon request. 4.Royal Blue product is binned by radiometric power and peak wavelength rather than photometric lumens and dominant wavelength.

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. Lumileds projects that white, green, cyan, blue, and royal blue Luxeon III products will deliver, on average, 70% lumen maintenance at 50,000 hours of operation at a 700 mA forward current or 50% lumen maintenance at 20,000 hours of operation at a 1000 mA forward current. Lumileds projects that red, red orange, and amber Luxeon III products will deliver, on average 50% lumen maintenance at 20,000 hours of operation at a 1400 mA forward current. This performance is based on independent test data, Lumileds historical data from tests run on similar material systems, and internal Luxeon reliability testing. This projection is based on constant current operation with junction temperature maintained at or below 90C. Observation of design limits included in this data sheet is required in order to achieve this projected lumen maintenance.
