I sometimes joke that if I can't afford a full-sized version on something, for austerity I will settle for a scaled-down version. Here is my small collection of "austerity" lanterns.
These are just cheap, older keychain gadgets, nothing special. The Couglan's lantern is LED, runs on 2xCR2032. The little Coleman replica has small incan bulb, uses LR44. The tripod lamp is a replica of this style of full-size worklight which was popular a dozen or more years back.
