The Xeno with its rubber bumpers reminds me a bit of the old Rayovac Indestructible series lights.

Rayovac Indestructibles used to be a a series of extremely durable and quite cheap lights. They got their durability from relatively light weight, plastic construction, and liberal use of rubber bumpers on the outside of the lights.

I haven’t checked to see if Rayovac still makes that line and whehter they still use similar construction.
