Nitecore NU27 600 Lumen Ultra-Light Outdoor Headlamp – USB-C Rechargeable

Nitecore NU27: Ultralight, multi-temperature outdoor headlamp

Designed for outdoor enthusiasts and professionals who value balance between weight, brightness, and battery life, the NU27 packs strong performance into a featherlight frame. Weighing just 56 g with the headband, it sits comfortably on the forehead while delivering robust illumination up to 123 meters and up to 600 lumens when needed.

Color temperature versatility

The NU27 uses MCT LEDs developed by NiteLab from UHE LEDs, offering three color temperatures: 3000K warm, 4500K neutral white, and 6500K cool white. Warm light helps reduce glare in fog or rain, neutral white provides natural task lighting for everyday activities, and cool white mirrors daylight for crisp, focused visibility during fast-paced outdoor tasks.

Optics and light quality

TrueVision+ technology delivers a uniform, soft beam, while a large reflective surface enhances efficiency. A 955.016 mm² reflective area and a matrix-design optic create a broad, 50.3 mm emitting surface for clear throw and expansive coverage.

• TrueVision+ maintains even brightness across the field of view
• Light transmission exceeds 94% to minimize loss

Power and endurance

A built-in 850 mAh Li-ion battery with USB-C recharge offers reliable runtime: about 6.5 hours at 200 lumens and up to 57 hours in ultralow. An auxiliary red light provides two brightness levels and slow flashing for signaling in low-light scenarios.

Durability and versatility

With IP66 dust and water resistance and drop protection up to 1 meter, the NU27 is built for daily outdoor use. A versatile clip lets you convert it into a cap light, shoulder light, or backpack light for flexible carry.

Use cases

Ideal for night hikes, camping, trail running, maintenance tasks, and early-morning expeditions. The red auxiliary light supports signaling and preserves night vision during low-light activities.
