The NU25 MCT UL is the weight and price pick. Nitecore lists it at 47 g including the bracket and headband, about half the weight of the Petzl ACTIK CORE, and the Nitecore Store sells it for $36.95, the lowest price on this list. Output tops out at 400 lumens with a 132 m throw, and the dual-core LEDs offer warm (3,000K), neutral (4,500K) and cool (6,500K) white light plus red, with 4 brightness levels and 3 special modes. Nitecore rates it IP66 for dust and water and 1 m for impact. Two differently shaped buttons let you work it by feel. The tradeoff is the battery: a built-in 700 mAh cell gives a 45 h maximum runtime and charges over USB-C, but it cannot be swapped, so a week-long trip needs a power bank. For thru-hikers counting grams and anyone buying a first headlamp, that is a fair trade.
