Nitecore TUP LED Keychain Light 1000 Lumen OLED Display Rechargeable Everyday Carry Pocket Flashlight

Complete with five brightness levels, four user and lockout modes, a built-in USB-rechargeable Li Ion battery pack, a stainless steel ring pull and deep carry pocket clip, we didn't think the Nitecore TUP LED Keychain Light could fit anything else in under 3". Imagine our surprise when we saw the multifunctional OLED Real-time Display, built right into the top of the flashlight! This intelligent display shows battery and voltage level, current brightness level, selected user-mode, and real-time remaining runtime, so you'll always know when you need to charge up.

Nitecore knows a good flashlight should be user-friendly and easy-to-use, and the Nitecore TUP LED Keychain Light is a shining example of that innovative functionality. With five brightness levels ranging from 1000 to 1 lumens, the Nitecore TUP has a little something for everyone. The 'Daily' user mode is for standard usage, while 'Demo' mode automatically shuts off after 30 seconds of inactivity to protect against accidental operation and battery consumption. In addition, two lockout modes are available to protect against accidental activation. 'Full-Lockout' is best for traveling and storage, while the 'Half-Lockout' grants immediate access to turbo mode for emergency use. During regular use, a longer press on the power button functions as a shortcut to ultralow illumination.
