General Information Part Number Description LUXEON Altilon LEDs are tested and binned at 1000mA, with current pulse duration of 20ms. The part number designation for the LUXEON Altilon series is explained as follows: LAFL-C2S-XXXX Where: LAFL — designates standard prefix for LUXEON Altilon C — default 2 — designates number of chips (2 or 4) S — designates solder or spade lugs (S or L) XXXX — designates minimum flux bin The part number designation for the LUXEON Altilon Core series is explained as follows: LACL-C2S-XXXX Where: LACL — designates standard prefix for LUXEON Altilon Core C — default...

Optical Characteristics Measured and Typical Optical Performance by Part Number Table 1. Product Part Number Form Factor LUXEON Altilon LUXEON Altilon Core Notes for Table 1: 1. Lumileds tests flux values via a pulsed measurement at a case temperature of 25°C. 2. Minimum luminous flux guaranteed within published operating conditions. Lumileds maintains a tolerance of ± 10% on flux measurements. 3. ‘*’ Indicates the inclusion or exclusion of the spade lug connector, indicated with an ‘L’ for spade lug, and an ‘S’ for those parts without. See Part Number Description below for more details. Typical...

Typical Use Condition Matrix—Relative Flux Normalized to Tc = 25°C, 1000mA, 20 msec pulses The graphs below predict the relative flux under various use conditions normalized to the test conditions of 1000mA pulsed operation (20 msec pulse) at case temperature of 25°C. These graphs can be used to determine the effects of case temperature and forward current on the values of minimum and typical flux to define performance at the expected use condition. For example: Given a flux at Tc = 25°C and 1000mA (20 msec pulse) of 700lm for 1x4 configuration, the flux value under different conditions can be...
