You could put a liner in it, but as George says, that would be like selling fire extinguisher with every Ford Pinto. I'm a hillbilly but I can figure these things out, why do people who build rebreathers with a fatal design flaw, like the Cis-Lunar, continue to design around a bad design? Does it take a dummie like me to point these things out? Or maybe I'm not as dumb as I think I am! Maybe they think you are as dumb as they are!

However, it seems to me that Mag Light has made quite a business making Aluminum housed lights. The fact the Aluminum conducts electricity is a good thing. You have one less wire to worry about as the case could be used to carry current from the back of a stack of cells. In fact you could have NO wiring at all. I think cost of manufacturing and weight of such a light would be better arguments for why one would no want to make backup lights from Aluminum. Pound for pound plastics give a better bang for the buck in this (light) case. Molding and extruding plastics is faster, cheaper, and easier than milling or machining Aluminum. further, plastics are more than suitable for a "light" duty task like this.
