Notes for Table 4:
1.
Lumen maintenance generally describes the ability of a lamp to retain its output over time. The
useful lifetime for solid state lighting devices (Power LEDs) is also defined as Lumen
Maintenance, with the percentage of the original light output remaining at a defined time period.
L70 defines the amount of operating hours at which the light output has reached 70% of its
original output.
