Klarus XT12GT Pro Flashlight | 1600 Lumens, 850m Beam, USB-C Rechargeable

A single 21700 cell pushes this Klarus XT12GT Pro out to an 850-metre beam, enough to pick out movement across open ground, a compound perimeter, or a stretch of farmland well past where a standard handheld light stops being useful. The Luminus SFT40 emitter reaches up to 1600 lumens across six selectable modes, from close-range work up to a full-power Turbo burst.

Battery and Charging

Runs on a single rechargeable 21700 lithium-ion cell, 5000mAh capacity, 3.6V nominal, included in the box. Charges through the built-in USB-C port with the included cable, no separate charger needed, and holds up to 288 hours of runtime on lower brightness settings. A Klarus 18650 cell (2600mAh or 3600mAh) works as a spare or backup for anyone who already has one from another Klarus light, both protected lithium-ion cells rated for this kind of high-drain use.

Controls and Durability

Dual switch design, one on the tail and one on the side, gives one-handed access to all six modes (Low, Medium, High, Turbo, Strobe, SOS) without cycling past the one needed. Brightness memory recalls whatever mode was last used, rather than waking up on Low every time. The aluminium alloy body carries an IPX8 rating, built for deeper submersion rather than just rain or splashes.

Backed by a 60-month seller warranty, tested before dispatch, with support available after delivery. For a lower-priced Klarus with a zoom head instead of a fixed beam, see the Klarus A3.
