Named for its compact size, the Nitecore Thumb Rechargeable LED Key Chain Flashlight offers a variety of features despite its lightweight design of less than one ounce. Equipped with white and red LEDs that deliver up to 85 lumens of brightness, this flashlight has a tilting head that can adjust up to 120°.
On a single charge, the Thumb can last for 45 minutes at high power and up to 22 hours at low power. It features separate buttons for white and red LEDs. The upper button controls the white lights, allowing users to switch between high, medium, low, and blinking modes. Meanwhile, the lower button manages the red LED's constant-on and blinking options. By simultaneously pressing both buttons, the light enters lockout mode to prevent accidental activation, a feature that can be undone by pressing both buttons once more.
Incorporating protections against overdischarge, overcharge, and short-circuit issues, Nitecore has ensured the safety of the Thumb flashlight. An intuitive power indicator blinks during charging and turns green to signal a full charge. Constructed from durable polycarbonate, the flashlight includes a clip for easy attachment to a belt, pocket, pack strap, or hat.
