Product description

Klarus XT21X rechargeable tactical flashlight

A Cree XHP70.2 LED puts out 4000 lumens over a 316 metre beam, part of what made this line a search and rescue favourite, with a 5000mAh 21700 battery for real sustained runtime rather than a short, bright burst that fades quickly.

Charges over Micro USB with a charge indicator built into the side switch that turns green once the battery is ready, a small but genuinely useful detail for anyone charging the light overnight. Seven modes, Turbo through Eco plus Strobe and SOS, span a wide practical range.

Runtime by mode

  • Turbo: full 4000 lumens, 2.5 hours
  • Eco (lowest): up to 200 hours
  • Five further modes in between: High, Medium, Low, Strobe, SOS

Dual tail switch plus side switch control gives one-handed operation in either a normal grip or a fist hold, IPX8 waterproof aluminium body handles full submersion rather than just rain resistance, and a 5 year seller warranty backs the build. At 158g for the light itself and 229g as packaged, it sits solidly in the hand without being genuinely heavy to carry through a full shift.

The XT21X PRO adds a power bank function, the ability to charge a phone directly from the torch's own battery during a blackout.
