Nitecore Tube 2.0

The Nitecore Tube 2.0 is a keychain light weighing 9.6 g with continuously adjustable output from 1 to 55 lm, charged via USB-C. The flood-only beam with a 25 m range is meant for lighting close surroundings rather than throwing light down a trail, consistent with its role as a lightweight backup rather than a primary walking light. Unlike its sibling, the TUBE V2, it lacks a button lock — carried loose on a keychain or in a pack's side pocket, it can switch on accidentally and drain the battery. Runtime on the lowest setting reaches 58 hours, and the stainless steel key ring is rated to hold 35 kg, so it won't be the weak point of your keychain. At under 10 g and with splash resistance, it makes sense as everyday-carry emergency backup or a trail spare, with the trade-off that the missing lock is one thing the slightly pricier lock-equipped variants get right.
