400 lumen head torches: understand the output you need

A head torch around 400 lumens can suit varied outdoor tasks, but a maximum figure does not show how long that output lasts or how the beam is shaped. Compare distance, spill, lower settings and runtime for the mode you plan to use. Petzl lists ACTIK and TIKKA CORE at 450 lumens, useful neighbouring examples when judging model options rather than a strict category boundary.
