The intensity of a street light is vastly higher. They typically produce 10x-100x more foot-candles versus a full moon on a clear night at a bright latitude.
Even under ideal conditions, the earth receives ≤1 lumen per square meter of light from the moon. A single streetlight can project tens of thousands of lumens (or more) over a relatively small area.
