You'd really have to be there at the perfect time to catch it before it hits the ground. Maybe on a windy day you could go back to this light. You could at least maybe get the door if the refractor breaks
This is why I feel that all lights should have hinge keepers so that if this happens, the door won't come unhinged. Maybe with a long pipe or something you could push the door back up and latch it from the ground lol. (or push it the other way and snag it lol)
