Night Photography: Street Light

I'm always wondering how bright street light is as the environment I used to take night images are always "bundled" with them, and found this interesting information in the internet, would like to share it here in case anyone is interested -

While street light is extremely strong(look at the lumens it produced), we can always overpower it easily, and using strobe is definitely not a problem, if you want to overpower street light with flashlight(imagine most of flashlight we have are in between of 1-250 lumens), as long as our subject is not too closed to street light or in the shade, we can do so easily.
