Are you sure you have a ZeusRay? The exact same body shape is available from a lot of places as a fixed, non-zoom flashlight.
If it’s a ZeusRay then the head is stuck in place for some reason. Is it giving you a floodlight or a spotlight?
Try twisting the head one way and the body the other, back and forth a bit, and see if it starts to move.
Could be there’s some grit jamming it.
Try looking through trying to consolidate all ZeusRay posts
“trying to consolidate all ZeusRay posts”
That’s the attempt to gather up all the ZeusRay information in one place rather than have it scattered around in multiple threads.
