What it is and what it is for
The NITECORE MH40 PRO is a long-range flashlight designed to deliver a concentrated, high-intensity beam for applications such as hunting, search and rescue, patrolling and tactical tasks. The manufacturer markets it as an "Ultra Bright Long Range Hunting Flashlight," providing projection suitable for distant targets.

Key features
The MH40 PRO offers a maximum output of 3,500 lumens and a maximum beam distance of 1,300 meters (peak beam intensity 423,000 cd). It uses a NiteLab UHi 40 MAX LED and an SMO reflector to produce a focused beam. The light includes ATR temperature regulation, is rated IP68 (submersible to 2 m) and impact resistant to 1 m. Using the NBP100R battery recommended by the manufacturer, runtime can reach up to 62 hours. Dimensions recorded on the supplier document are 60.6 x 60.6 x 250.4 mm; the official datasheet lists 256 mm length and a 65 mm head. Construction is aircraft-grade aluminum alloy with HA III hard-anodized finish per the official sheet.

Compatibility and power
The manufacturer recommends the NITECORE NBP100R rechargeable battery (10,000 mAh) and states compatibility with two 21700 cells that meet the discharge requirements. The user manual explicitly warns against using 18650 cells, primary CR123 batteries, RCR123 types, and 21700 "flat top" cells.

Box contents and accessories
According to the official manual, the package includes the NBP100R rechargeable battery, the wireless remote switch, spare O-ring, lanyard, USB-C charging cable, holster and the wireless remote switch set (hook-and-loop fastener, straps and optional Picatinny rail mounts).

Return-avoidance notes
