Photometry

CR22-32L-30K BASED ON CSA REPORT TEST #: 2362893-01

Luminaire photometry has been conducted by a NVLAP accredited testing laboratory in accordance with IESNA LM-79-08. IESNA LM-79-08 specifies the entire luminaire as the source

resulting in a luminaire efficiency of 100%.

Application Reference

Based on CR22-32L-30K Luminaire

1

Lumen maintenance values at 25˚C are calculated per TM-21 based on LM-80 data and in-situ luminaire testing

2

In accordance with IESNA TM-21-11, Projected Values represent interpolated value based on time durations that are within six times

(6X) the IESNA LM-80-08 total test duration (in hours) for the device under testing ((DUT) i.e. the packaged LED chip)

3

In accordance with IESNA TM-21-11, Calculated Values represent time durations that exceed six times (6X) the IESNA LM-80-08 total

test duration (in hours) for the device under testing ((DUT) i.e. the packaged LED chip)
