I like my OLight S1R rechargeable light for outdoor use. While camping, having some "lantern-like" light in your tent can be helpful. I Remixed the excellent "OLight R50 Pro - traffic wand" by @ibisonline to be sized for my smaller light - but also make the diffuser smaller and lighter. It weighs in right at 3 or 4grams (my scale bounces between the two). It's a tight fit, so you may want to scale it up a hair if you have issue. I printed mine in glow in the dark PLA for added gee-whiz.
