Cordite? Surely you jest. [img]/ubbthreads/images/graemlins/wink.gif[/img] I don't know where any could even be found since the early days of World War II. It was a late 1800s, very early 1900s British propellant.
I still haven't had a Lithium cell burn or blow up. But a friend did last year with a couple of new, Chinese-made cells in a brand new UK 2L I had bought her. I sent the whole mess to one of the posters on this thread to examine and toss.
Most that I know locally have transitioned to single CR123A celled lights for lights kept loaded. These aren't people with need for an always loaded 2x123 light.
One lady friend some time ago traded her SL Twin Task 2L for the 1L version. As a glovebox light it'll do everything the 2L does, just doesn't throw as far with the incandescent lamp.
Most all of the lights I use frequently and therefoer keep loaded are single cell lights with a Lithium primary cell or a Lithium-Ion rechargable battery.
I'm not so concerned for one blowing up and hurting me as for one exploding, starting a fire and destroying a house, hotel, airplane or car.
