Petzl Actik Core Headlamp

Finding your own tent among hundreds of identical ones at 2 a.m. is a job for both hands, which is why a headlamp beats a phone flashlight. The Actik Core puts out up to 625 lumens, has a red mode that will not blind your neighbors, and a lock that stops it switching on and draining inside your bag. The smartest detail for a long weekend is the hybrid power: charge its battery by USB-C before you leave, and if it runs flat, three ordinary AAA batteries will do. It weighs 3.1 oz and is rated IPX4, so it handles rain and splashes but is not fully waterproof. At around $88 it costs more than budget lamps.
