Selection Guide
Notes:
1. θ1/2 is the angle from optical centerline where the luminous intensity is 1/2 of the optical peak value.
2. Luminous intensity/ luminous Flux: +/-15%.
* Luminous intensity value is traceable to the CIE127-2007 compliant national standards.
Absolute Maximum Ratings at TA=25°C
Electrical / Optical Characteristics at TA=25°C
Notes:
