Notes for Table 1:
1. Lumileds maintains a tolerance of ±2 on CRI and ±6.5% on luminous flux measurements.
2. Typical CRI is approximately 2 points higher than the minimum CRI specified, but this is not guaranteed.

Notes for Table 2:
1. Total angle at which 90% of total luminous flux is captured.
2. Viewing angle is the off axis angle from the LED centerline where the luminous intensity is ½ of the peak value. Radiation pattern slice measured in the plane parallel to one of the four sides of
the emitter.
3. Represents optical characteristics when mounted on a silver reflective substrate.

Notes for Table 4:
1. Proper current derating must be observed to maintain the junction temperature below the maximum allowable junction temperature.
2. Residual periodic variations due to power conversion from alternating current (AC) to direct current (DC), also called “ripple,” are acceptable if the following conditions are met:
– The frequency of the ripple current is ≥100 Hz and amplitude ≤15% of the maximum DC current are acceptable
– The average current for each cycle does not exceed the maximum allowable DC forward current at the corresponding maximum junction temperature
– The maximum amplitude of the ripple does not exceed the maximum peak pulsed forward current
3. Pulsed operation with a peak drive current equal to the stated Peak Pulsed Forward Current is acceptable if the pulse on-time is ≤ 5 ms per cycle and the duty cycle is ≤ 50%.
