Everyday-carry flashlights are sold on peak lumens, but peak output rarely lasts more than a few minutes. We compare a 21700 high-output light, a flat multi-function light and a CR123A tactical light on the specs that decide how they behave in the pocket and in use.
A headlamp is the light most people actually reach for in the dark, whether that is on a trail, under a sink or at a campsite. We compare a hybrid rechargeable, an AAA-powered classic and a high-output 18650 lamp on the specs that matter on your head.
