Nitecore HA23 UHE Green Headlamp - 600 lumens

Fitted with 4 MCT UHE LEDs, the headlamp delivers a maximum brightness of 600 lumens and illuminates distances up to 132 m. On the lowest setting of 6 lumens, the light can operate continuously for 97 hours when using three AAA batteries or up to 125 hours with a Nitecore HLB1500 rechargeable battery (not included).

MCT UHE LEDs provide three color temperature options: natural white light at 4500K, warm light at 3000K, and cold white light at 6500K.

Equipped with TrueVision+ technology, the model delivers enhanced brightness through a beam radius and light transmission reaching up to 94%. Illuminated objects are displayed with greater realism, featuring a more natural and three-dimensional look.

Constructed from robust polycarbonate, the housing offers exceptional durability. High-grade raw materials and sealing components ensure compliance with the demanding IP68 protection standard—providing complete defense against dust penetration and allowing for prolonged submersion in water up to 2 meters deep. The flashlight is also engineered to withstand impacts from drops up to 1 meter.

The HA23 operates using either three AAA batteries or the Nitecore HLB1500 rechargeable battery (sold separately). Two conveniently placed switches atop the main body enable adjustment of both color temperature and brightness levels. Simultaneously pressing both buttons engages a lock function to prevent accidental activation. A battery indicator is located on the front, just beneath the LEDs.
