Example: Calculate Streetlight Watt of each Luminaire of Street Light Pole having following Details, 1  Road Details: The width of road is 7 Meter. Distance between each Pole (D) is 50 Meter. 2  Required Illumination Level for Street Light (L) is 6.46 Lux per Square Meter. Luminous efficacy is 24 Lumen/Watt.
