Nitecore HA23 UHE Headlamp – 600 Lumen, 3 Color Temperatures, Green

Overview

Meet the Nitecore HA23 UHE headlamp, a compact light that can brighten your night without weighing you down. It delivers up to 600 lumen using dual-core MCT (Multiple Color Temperatures) UHE LEDs, offering three color temperatures: 3000K warm light for cozy campsites, 4500K neutral white for chores and map reading, and 6500K cool white for detailed tasks in dim environments. Auxiliary red LEDs provide a night vision-friendly option that preserves your peripheral awareness. The unibody optical lens system features precision facets for a balanced beam that feels natural on trails and at the campsite. The Green housing makes the light easy to spot in gear bags and on the trail.

Power, versatility, and one-handed use

The HA23 is built for field versatility. It runs on three AAA alkaline batteries out of the box, and it can also be powered by NiMH cells or the Nitecore HLB1500 Li-ion battery pack. Two distinct button shapes are designed for easy one-handed operation, even when you're wearing gloves. In addition to standard brightness, you’ll find three special modes and two red-light brightness options to tailor the output to your environment.
