For LED lamp, light engine and luminaire manufacturers to receive an Energy Star certificate for their products, the US Environmental Protection Agency (EPA) requires that the LEDs used in these products must comply with the LM-80 (Lumen Maintenance) test requirements. LM-80 test reports provide evidence that the LED …

Lumens to watts calculation formula Energy saving lamps have high luminous efficacy (more lumens per watt). The power P in watts (W) is equal to the luminous flux ΦV in lumens (lm), divided by the luminous efficacy η in lumens per watt (lm/W): P(W) = ΦV(lm) / η(lm/W) Lumens to watts table Lumens to watts calculation See also
