pole distance
Spacing between each Pole=(LL*CU*LLD*LDD) / Eh*W; Spacing between each Pole=(33200Ã0.18Ã0.8Ã0.9) / (5Ã11.5) Spacing between each Pole= 75 Foot. Space Height Ratio = Distance between Pole / Road width; Space Height Ratio = 3. Which is less than define value. Spacing between each Pole is 75 Foot. (2) Calculate Street Light Luminaire Watt: 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.
