IES LM-80 Test report for LED
According to IES LM-80 standard, lumen maintenance is the remaining luminous flux output (% of the
initial output) at a selected operating time.
According to IES TM-21 standard, L(D) is the lumen maintenance life expressed in hours where 70% of
initial lumen output is maintained, with D the total duration time for the effective tests, in hours. The life
projection is limited to 6 times the total duration of the effective tests.
Chosen conditions for IES LM-80 Test:
Case Temperature: 70°C interpolated from 50 to 85°C
Drive Current: 700 mA
Total Duration Time (D): 10,000 hours
Lumen Maintenance at L = 82.6 %
Average L Extrapolation following IES TM-21 method:
L(10,000) ≥ 60,000 hours
Extrapolation for LED in Cupola
According to the driving and thermal conditions in the cupola(s), the average L70 Life Projection fol-
lowing IES TM-21 method gives:
LED Projected Life Time: L70(10,000) ≥ 60,000 hours
