Street light lumens. Typically the higher the wattage the higher the lumens and the more light output. It refers to a light bulb s brightness intensity of light and visible light emitted. Led street lights produce from 3600 lumens to 38 760 lumens. Unlike other models the yuelguang solar street light is also equipped with light and motion sensors.
That is most street light optics would distribute the high and very high zonal lumens below the limits required for this rating. Residential applications of led street lights generally call for lumen packages in a range for 3000 to 5000 lumens.

This depends on how many lumens per w of a single led lamp bead and secondly how about the light output of the reflector of the lamp. In this lumen range most street light luminaires would have a g rating 1. So how many lumens do you need for outdoor lighting. From what i have read low pressure sodium puts out approx 180 lumens watt so a 100 street light would be 1800 lumens a 400 watt bulb would be around 72 000 lumens using that figure.
