Notes for Table 10:
1.Lumileds maintains a tolerance of ± 0.06V on forward voltage measurements.
2.Dynamic resistance is the inverse of the slope in linear forward voltage model for LEDs. See Figure 3.
3.Measured between 25ºC ≤ T_J ≤ 110ºC at I_F = 1400mA.

Notes for Table 11:
1.Proper current derating must be observed to maintain junction temperature below the maximum. For more
information, consult the LUXEON Design Guide, available upon request.
2. LEDs are not designed to be driven in reverse bias. Please consult Lumileds’ Application Brief AB11 for
further information.
