Our Verdict
The NU25 MCT UL packs an impressive amount of functionality into a 47g package. With warm, neutral, and cool white outputs, plus a red light mode, it adapts well to different conditions, from campsite admin to early alpine starts.
I’m particularly impressed by the versatility of the beam options and the fact that it’s USB-C rechargeable with a simple two-button interface. The low-profile headband holds securely, and the glow-in-the-dark detail is surprisingly helpful. At 400 lumens on high, the beam reaches far enough for cautious night navigation, while lower settings conserve battery without feeling dim. The IP66 rating means it’s fully dustproof and can handle heavy rain from any angle, so I wouldn’t hesitate to use it in poor weather., lockout function, and diffuser sack round out a very well-considered design.
