Waterproof and tough, with a peak output of 1000 lumens and maximum runtime of 160 hours, the TK20R Rechargeable LED Flashlight from Fenix is a tactical/professional light that's also well-suited to personal and recreational use. No need to worry about buying fresh batteries – just plug it in and charge it up.

The TK20R features a tailcap momentary and constant-on pushbutton switch and a side switch for cycling through its four brightness levels and strobe setting. Brightness settings range from 10 lumens on low to 1,000 on turbo. The light comes from a Cree XP-L HI V3 LED white LED with a lifespan of 50,000 hours. The light runs on a single, included 18650 rechargeable battery or two CR123 batteries, and features active and passive over-heat protection, digitally regulated output, and reverse-polarity protection.

Complementing the light's performance is a lightweight and durable dual-layer aluminum alloy body with a protective corrosion and scratch-resistant type III hard anodized finish. The light is impact-resistant tested to 3.3' drops, and IP68-rated to be submersible to a depth of up to 6.6'.
