SRP, GE M400A1 Powr/Door (1980's) - Phoenix, AZ

A General Electric M400A1 full-cutoff HPS model used throughout the 1980's-90's all around Phoenix. Much of these have since been replaced by the rather generic GE M400A3 Full-Cutoff that have popped all over the place (which UI in Connecticut replaced about 99% of their streetlights with a few years ago).

I've always liked this GE model. :)
