The Nitecore MH12 Pro is the first LED flashlight featuring a NiteLap UHi-LED. The UHi-LED is a proprietary development by the manufacturer NiteLap, which, like Nitecore, is part of the Sysmax group. The UHi-LEDs offer significant advantages over other LED manufacturers such as CREE, Luminus, or Osram: higher light output, significantly greater spot intensity, much longer range, and extended runtime. The performance specifications of the MH12 Pro are impressive and unmatched for the size of the flashlight: 3300 lumens brightness, 505 meters range, USB-C charging, and a 5300mAh battery. The Nitecore MH12 Pro is turned on via the tail switch, and changing the brightness levels is done through the mode switch on the head of the flashlight. On the right side of the mode switch, 4 green LEDs indicate the battery charge status, while 4 blue LEDs on the left side show the currently selected brightness level. Users have access to two modes: Daily Mode and Tactical Mode. The modes differ in the number and arrangement of brightness levels and special modes. An integrated optical sensor immediately reduces the brightness of the MH12 Pro to prevent damage to the flashlight or surrounding objects. An improved surface structure of the battery tube ensures a secure grip even with wet hands or while wearing gloves.
