NITECORE UT27 2024 Headlamp LED

What it is and what it's for:
The NITECORE UT27 2024 is an LED headlamp designed for trail running, night running, trekking, hiking, camping and emergency lighting. It provides frontal illumination with selectable color temperatures and a wide, uniform beam.

Main characteristics:
The lamp produces up to 800 lumens. The supplier invoice lists a beam distance of 130 meters (note: the official NITECORE product page/manual reports a maximum beam distance of 168 meters; see notices). The body is made of polycarbonate (PC). It uses 2 × quad-core NiteLab MCT UHE LEDs with selectable color temperatures: 3000 K (CRI 97), 4500 K (CRI 83) and 6500 K (CRI 73). Modes include TURBO (800 lm), HIGH (500 lm), MID (280 lm), LOW/ULTRALOW (100 lm) and red auxiliary light; runtimes per FL1 table with HLB1500 battery: TURBO 2 h 30 min, HIGH 3 h 30 min, MID 6 h 30 min, LOW 14 h 30 min. Features dual-lens TrueVision+ optics, dual switches for separate warm/cool control, APC for near-zero standby consumption and 90° tilt. Rated IP66 and impact resistant to 1 m.

Compatibility:
The unit includes and recommends the NITECORE HLB1500 rechargeable battery pack (1,500 mAh, USB-C). As an alternative it supports 3 × AAA (alkaline or Ni-MH). The manual indicates some 10400 cells (LFP/Li-ion 10400) are not compatible.

Box contents and accessories:
The supplier note lists battery and headband included. The official manual specifies 1 × HLB1500 (1,500 mAh), 1 × USB-C to USB-C cable, 1 × headband, 1 × diffusing stuff sack and 1 × clip. See notices to confirm final retail contents.

Return-avoidance notes:
Verify battery type with the customer: HLB1500 is recommended; some 10400 cells are incompatible. Confirm which dimensions and beam distance to display, since invoice and official manual differ.
