Klarus XT20 + BK20AB Kit - Dual Head XM-L 1200 Lumen LED Flashlight and Bike Light

The XT20/BK20 Kit contains all the parts you need to have both a 1200 lumen flashlight and a 1200 lumen bike light.  The XT20 and BK20 are also available separately.

XT20:

The new KLARUS XT20 is stealthy and powerful. Its slender form and magnificent power (1200 lumens) makes it ideal as a night patrol flashlight and searchlight.

The super bright XT20 has two heads, which produce a wider, more intense beam than single head flashlights. Each head contains a high power CREE XM-L U2 LED, which allows the XT20 to pierce the darkness with 1200 lumens of light from just two 18650 batteries.

The new KLARUS XT20 uses the innovative XT series dual-button tail switch, which provides extremely fast access to the strobe mode. The unique XT tail switch also allows you to fully operate the light with just your thumb. So you don't need to fiddle with buttons in two different places.

With so much light, an intense strobe effect and slender design, the XT20 is an ideal choice for searching (Police and Search & Rescue), CQB, exploration and as an automobile standby flashlight. It can also be weapon mounted and used with the KLARUS ED10 pressure switch for remote activation.

Switch and Operations

Momentary activation: Click anywhere (except strobe switch/circular button) on the pressure pad to active momentary-on mode.

Constant-on: Press and hold the constant-on switch for more than 1 second for constant-on mode with high output.

High-Mid-Low Outputs: With constant-on activated, press the constant-on switch for more than 0.6 second to cycle through High-Mid-Low modes. Click anywhere on the pressure pad (all but the strobe switch) to turn the light off.

Strobe: When the light is on or off, click the strobe switch (circular button) to access the strobe function. To deactivate strobe, click the strobe switch again--- this will switch to the previous output(s). For example, if it was turned off prior to accessing the strobe function, the unit will return to off mode. If it was set previously to the mid output mode, the unit will return to mid output mode.

Usage and Maintenance

• Do not shine light directly into eyes.
• Remove battery when stored for extended periods.
• Replace and lubricate O-Rings as needed to maintain IPX-8 rating.
