How to convert luminous flux in lumens (lm) to electric power in watts (W) .You can calculate watts from lumens and luminous efficacy.umens to watts calculation formula. The power P in watts (W) is equal to the luminous flux Ï V in lumens (lm), divided by the luminous efficacy Î· in lumens per watt (lm/W): P (W) = Ï V(lm) / Î· (lm/W). So. watts = lumens / (lumens per watt).
