the existing pole was struck by a car and is Splintered,cracked and leaning....new pole is next to it,i assume they will transfer the light from the old pole to the new pole as they usually do. Streetview Here.
The current and previous (1985-1997) GE M-400 versions tends to hold the door much better than the smaller M-250 versions....although 400s do lose doors, just not as often as the 250s
Not brittle, I have seen glass survive!!! There was a GE M-400A2 in a parking lot that lost the door and I saw the door from below with an fully intact glass!!!! So they don't always break! My linemen friends when they have to replace a streetlight by climbing a pole, and they have to drop the old one, there's times it will break, other times it didn't break, I had one of them tell me he dropped an AE 113 with glass and it went to the ground completely intact!
Probably depends on how you drop it, some areas of the glass are thicker and stronger than others. I sure wouldn't have to take down a big heavy street light suspended from the pole with no truck. Anyway, National Grid has some big bucks, so they can afford cherry pickers.
Thats good, here there is a 60% chance the light will get transfered, a 25% chance a new light will be put up and the odd time (15%) that they won't even put the light back up and I have to complain
