Nitecore NU20 Classic

The Nitecore NU20 Classic is an ultralight 38 g headlamp with a built-in USB-C rechargeable battery, removing the need to carry spare disposable cells. Seven light modes combine white spot, white flood, and red light, so a single unit covers everything from reading a map at camp to punching a beam down a dark trail. Peak output of 360 lm with a 109 m beam distance is enough for typical night hiking on a marked path, and the quoted 97 h runtime applies to the lowest setting — actual battery life scales down sharply as you move up through the brighter modes. A lock mode prevents accidental activation inside a pack, and IPX6 water resistance handles rain and splashes without issue. With an adjustable headband and a weight under 40 g, the NU20 Classic sits in the sensible middle ground between output and pack weight — a solid choice for weekend trips and longer hikes where a bulkier lamp running on replaceable batteries isn't worth the extra bulk.
