Loved my carbide lamps back in the day!! Heat and light all in one, usually reliable appliance. Now my lamps are just treasured antiques, sitting on the shelf.

The problem is obtaining and maintaining carbide, which decomposes readily around humidity and water. Just not worth the hassle.

I have embraced 18650 batteries, with their great capacity, inserted into beautifully designed lights. But they will never replace the warmth of a hand held carbide, cradled in one's hands, walking along a trail on a cold, frosty night....

The geezer will now be silent.
