Example: Calculate Streetlight Watt of following Street Light Area, 1  Required Illumination Level for Street Light (L) is 6 Lux per Square Meter. 2  Luminous efficacy (En) is 20 Lumen per Watt. 3  Required Street Light Area to be illuminated (A) is 1 Square Meter.
A flux of 1,000 lumens, concentrated into an area of one square metre, lights up that square metre with an illuminance of 1,000 lux. Steps: To convert from Lux (lux) to Lumen (lm) insert the value in lux, distance between the light source and work surface as well as the viewangle of the source lamp. Click on Lux to Lumen .
