Petzl e+lite

The Petzl e+lite is an emergency headlamp designed to take up almost no space or weight until you actually need it. At 26 g and just 40 lumens, it's not meant as a primary light for night hiking but as a backup for when the main headlamp dies or gets lost — its 26 m beam distance covers basic orientation and camp tasks. The standout spec is IPX7 (submersible to 1 m), well beyond the IPX4 rating of Petzl's regular headlamps, making it a reliable choice for rain or water sports. The CR2032 batteries have a claimed 10-year shelf life in standby, so the lamp can sit in a first-aid kit or emergency stash for years without needing a check. Five modes, including red light and strobe, cover emergency signaling use as well. For ultralight hikers and climbers, the e+lite is a textbook example of redundancy at minimal weight cost — 26 g in a first-aid kit or safety pouch is a reasonable price for the certainty of a working light if the primary headlamp fails.
