SBT-90-R Output vs.Temp., Lifetime and Spectrum

Note 1. Median lifetime estimate as a function of junction temperature at 1.5 A/mm2 in continuous operation. Lifetime defined as time to

70% of initial intensity. Based on preliminary lifetime test data. Data can be used to model failure rate over typical product lifetime.

Note 2. Lumen maintenance vs. time at 1.5 A/mm2 in continuous operation, junction temperature equal to 25°C.

Note 3. Typical spectrum at current density of 1.5 A/mm2 in continuous operation.
