Nitecore TIP CRI 2017 Rechargeable Metal Keyring Light (Green)

Built with an aluminum housing and a lumen output as high as many full-sized flashlights, the silver TIP 2017 Rechargeable Metal Keyring Flashlight from Nitecore is small enough to carry on a keyring, so you'll always have it handy. It features a straight-to-Turbo option, recharges via USB, and comes with a multi-purpose clip for your pocket or hat brim, which also covers the switches to prevent accidental activation and protects the USB port from water and dust.

The TIP CRI 2017 employs a Nichia LED with a Color Rendering Index value greater than 90, which mimics sunlight for vivid, accurate colors and reduced eye fatigue. Its main brightness settings — ultralow, mid, and high — are accessed by clicking the mode button. You can turn on the light straight to turbo by holding the mode button for a full second. Choose between two operating modes: Daily mode shuts the light off automatically after 30 seconds of inactivity to save power, while in Constant-On mode, the light stays on until you turn it off. You can switch from Daily to Constant-On with a simple press of the power switch.

The TIP offers big-light technologies such as Advanced Temperature Regulation to prevent overheating, precision digital optics technology for a long beam throw, and constant current circuitry for consistent performance. It has built-in overcharge, over-discharge, and short-circuit protection and stops drawing power automatically when it is fully recharged. Runtimes range up to 46 hours. There's an indicator light that lets you know how much battery power you have left, and a lockout mode to prevent the light form being accidentally turned on in your pocket or bag.
