Note 10: Special design considerations must be observed for operation under 1A. Please contact Luminus for further information.

Note 11: SST-90 R LEDs are designed for operation to an absolute maximum current as specified above. Product lifetime data is specified at recommended

forward drive currents. Sustained operation at or beyond absolute maximum currents will result in a reduction of device life ime compared to

recommended forward drive currents. Actual device lifetimes will also depend on junction temperature. Refer to the lifetime derating curves for

further information. In pulsed operation, rise time from 10-90% of forward current should be larger than 0.5 microseconds.

Note 12: Lifetime dependent on LED junction temperature. Input power and thermal system must be properly managed to ensure lifetime. See charts on page

8 for further information.

Optical & Electrical Characteristics Notes

Note 4: All ratings are based on a junction test temperature T

Note 5: Listed drive conditions are typical for common applications. SST-90 R devices can be driven at continuous currents ranging from <1.0 A to

9.0 A and at duty cycles ranging from 1% to 100%. Drive current and duty cycle should be adjusted as necessary to maintain the junction

temperature desired to meet application lifetime requirements.

Note 6:

Unless otherwise noted, values listed are typical. Devices are production tested and specified at 3.15A. Other values are for reference only.

Note 7: Total flux from emitting area at listed dominant wavelength. Reported performance is included to show trends for a selected power level.

For specific minimum and maximum values, use bin tables. For product roadmap and future performance of devices, contact Luminus.

Note 8: In CIE 1931 chromaticity diagram coordinates, normalized to X+Y+Z=1.

Note 9: For reference only.
