A street light is raised source of light on the edge of the road or a walk way. The new street lighting technologies that many cities-Kigali inclusive are struggling with effectively implementing in their street lighting is the Light Emitting Diode(LED) driven by the promise of significant energy and maintenance savings it provides. LED emits a white light that provides high levels of scotopic lumens allowing street lights with lower wattages and lower photic lumens to replace existing street lights.
LED lamps improve night time visibility and safety through better color rendering more uniform lighting distributions and elimination of many dark areas between poles and also reduces light pollution because too much lighting in urban areas can hide the stars and interfere with astronomy and migration of many bird species.
