No...this one is a GE M-250R without the "1" the R1 version is the ones with a bail latch.....this one has a button with thumb latch so its only a "R" good eye on Dave's mistake! But I found YOUR Mistake......but still good correcting though!
Update: Seen this at night, this does not work. Edison has a policy that street lights over 15 years old are to be replaced when they need servicing. So this may come down.
