Figure 1. Axial Intensity (cd) and Illuminance (lux) vs. Drive Current, T_J = 25°C
Notes for Table 1 & Figure 1:
1. Minimum illuminance performance guaranteed within published operating conditions. Philips Lumileds maintains
a tolerance of 10% on illuminance measurements.
2. LUXEON types with even higher luminous flux levels will become available in the future. Please consult your
Philips Lumileds Authorized Distributor or Philips Lumileds sales representative for more information.
3. Philips Lumileds maintains a tolerance of ±0.06V on forward voltage measurements.
4. All values assume a junction temperature T_J of 25°C.
5. For flash modes, it is recommended that the drive current be as high as possible (up to 1000 mA) for optimal results.
6. Dynamic resistance is the inverse of the slope in linear forward voltage model for LEDs.
7. Measured between 25°C ≤ T_J ≤ 110°C at I_F = 1000mA.
