Maximum power, minimum size. That's the goal of Nitecore's T4K. The IP54-rated thumb-sized light uses four Cree XP-L2 V6 LEDs to pump out up to 4,000 lumens of light up to 228 yards in a 10-second burst, or 200 lumens for an extended period. Its keyring is rated for over 60 pounds and has a mechanical quick-release design for fast deployment. A dual-button design makes it easy to use, an OLED display shows brightness, battery level, and status, and the battery recharges over USB-C for convenience. Ships with an adjustable pocket clip for added carry versatility.
