Those smol circles depict the luminance of a street light.

The bigger circle shows the outermost (dimmest) values of the light. The smaller rings are brighter and reflect the values at the center of the light being emitted by the street lights.

This will give you a much better idea of what’s taking place. 

Look at the street lights & then look at the post below. 💙
