What is the distance between street lights?
30m to 50m
The optics play an important role and allow the lighting designer to adjust and tweak the light spread to suit the area being lit and select the most economical solution. So how far apart? You are likely to see street lights spaced approx. 30m to 50m apart – they are often spaced closer at junctions and on bends.
What are the main factors to be considered while designing a street lighting?
Main Factors in the Street Lighting Design Scheme
- Luminance Level Should be Proper.
- Luminance Uniformity must be Achieved.
- Degree of Glare Llimitation is always taken into Design Scheme.
- Lamp Spectra for Visual Sharpness depends on the Proper Luminaries.
- Effectiveness of Visual Guidance is also an important factor.
How many kWh does a street light use?
Most of the time, street lights are used for 12 hours a day. The average price in the USA is 10 cents per kilowatt-hour ($0.10/kWh). Consumption for 12 hours is (12 hours*100 watt) = 1200 watt-hours = 1.2 kWh.
