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)
