SKU: XT21X-1

Innovative Powerhouse LED Flashlight
Yet another high quality addition to the XT series of flashlights, the Klarus XT21X stands out from the pack as being the brightest of these tactical style lights. Housing a CREE XHP70.2 P2 LED, this light can reach output levels of up to 4000 Lumens!

That's a light level more commonly seen in searchlights, making the XT21X a great choice for search and rescue operations in hard to traverse areas. This light also features the XT Series' trademark dual tail switch design that makes it easy to turn on, off and shuffle through modes singlehandedly. Additionally, an integrated side switch can also be used for a more casual lighting experience.

USB Rechargeable
The Klarus XT21X is an all inclusive package, including both USB charging cord and a powerful 5000mAh 21700 battery. This light can charge quickly, easily and safely at any computer or wall mounted USB outlet. The side switch features a charge indicator that lets you know when the light is charging, and when it's ready to roll.
