Nitecore T4K Keychain Flashlight

4,000 Lumens, 4 x CREE XP-L2 V6 LEDs

The Nitecore T4K is a rechargeable keychain light that can fit in the palm of your hand and produce an astonishing 4,000 lumens that can reach distances of up to 209 meters. The T4K utilizes 4 x CREE XP-L2 V6 LEDs and gives you five brightness settings to choose from plus instant access to turbo, ultra-low, and the OLED display screen.

OLED Display, Dual Side Switch

The T4K has continued the popular dual side switch design that most of their keychain series use for easy operation. Similar to the Nitecore TUP, this light has an OLED display screen for real-time monitoring of mode, lumens, battery life, etc. for your convenience. When accessing turbo mode, a countdown progress bar will be shown on the display screen to indicate remaining time which is determined by by the thermal status of your light to protect inner components from overheating.

Two User Modes, Two Lockout Modes

To cater to users different needs, the T4K has two different user modes for short and long-term lighting. To ensure battery life, use the Demo mode - the light will automatically shut off after 30 seconds of not being used. For longer illumination times and manual shut-down, use the Daily mode. For added security, there are two lockout modes to prevent accidental activation in transport. Use lockout mode 1 (half lockout) for instant access to turbo with the mode button, and lockout mode 2 (full lockout) for both buttons to be disabled.

Nitecore T4K
December 6, 2021
This light is a monster pocket light. It's got settings all the way from 1 Lumen to 15 then 65 then 200 Lumens. The power button has a meter that tells you real time power left in each setting. If this isn't enough it has a 10 second burst up to a turbo 4,000 LUMENS.

To protect everything batteries, LEDs and your skin you can't press the power button repeatedly close together and keep getting 10 second bursts. You have to hold the power button down without releasing it to keep the turbo mode on which will drop back to 200 Lumens after the initial 10 seconds.

It's not a cheap light, but you are getting a lot for your money.

Build quality is superb. I really enjoy mine. You can still catch it on sale (December 6th) but it is on back order I believe. This makes a great selfie gift.
