Lightweight Design for All-Day Comfort
The Right Light for Every Moment - Life isn’t one-size-fits-all, and neither is light. That’s why the NU27 offers three carefully calibrated beams:
- Warm light for misty mornings or rainy evenings, cutting through fog without glare.
- Neutral white for balanced, natural tones that feel effortless on the eyes.
- Cool white for crisp clarity, helping you focus and stay alert during nighttime tasks.
Hands-Free, Truly - The NU27 adapts to you. Use the comfortable headband for classic wear. Or take it off, and clip the headlamp to a cap, strap, or belt. The MOLLE-compatible clip makes it easy to use in whatever way works best for you. It’s not just hands-free. It’s seamless.
More Than a Headlamp - The included diffuser sack takes the NU27 beyond the ordinary. Slip the headlamp inside, and you have a soft, ambient lantern—perfect for relaxing at camp, reading in your tent, or adding a warm glow to any moment.
Built for the Unexpected - Rain? Dust? Drops? No problem. The NU27 is IP66-rated for tough conditions and built with durable PC materials. It’s designed to keep going, even when things get rough. And with up to 57 hours of battery life and USB-C fast charging, you can trust it to be ready whenever you are.
Details That Matter - The NU27 doesn’t just deliver light—it delivers control. A lockout mode prevents accidental activation when stored in your bag. The intuitive power indicator ensures you always know how much battery you have left. It’s thoughtful design, in every sense.
