This is on the street where my house is. The entire road is still lit up with DX mercury lamps, which are probably 400w. I apologize for the poor quality photo; phone cameras can’t get good night shots from a distance. They’re not quite as green as on camera, but they are pretty dim now, since the lamps were last changed about 10 years ago. In a different part of the neighborhood, two were changed out for LEDs, though it was probably because the ballasts failed. Some of them are quite loud at this point.
