Nitecore T4K 4000 Lumen Super Bright EDC Flashlight

World’s Brightest Keychain EDC Flashlight
Carry unmatched power in the palm of your hand with the Nitecore T4K, the world’s most compact 4000-lumen (10-second burst) keychain light. Despite its thumb-sized design, it delivers an impressive throw of over 228 yards. The built-in mechanical quick-release keyring allows fast deployment, while the included adjustable pocket clip makes it a reliable everyday carry companion. Featuring an intuitive dual-button interface with instant turbo access, the T4K is a practical addition to any keychain, emergency kit, or outdoor setup.

Simple, Familiar Operation
The T4K’s dual-button layout keeps things straightforward: a power button for on/off and a mode button to cycle through brightness levels. The mode button also doubles as a turbo switch—press and hold for instant turbo, whether the light is on or off. With five brightness settings to cover any situation, the T4K ensures versatility in a compact form.

USB-C Fast Charging
Equipped with USB-C fast charging, the T4K fully recharges in under 1.5 hours, offering over 67 hours of runtime per charge. Its OLED display provides real-time updates on battery status and charging progress. Two lockout modes help preserve battery life and prevent accidental activation. Built with charging safeguards, an IP54 weather-resistant rating, and a 66-pound rated keyring, the T4K is rugged, reliable, and ready for anything.
