Klarus BK20 1200 Lumen Rechargeable Bike Light

The BK20 is specially designed as a ultra-bright, far-throwing, long run time, durable, shockproof, waterproof and easily detachable, quick easy operation bicycle light.

The BK20 was designed to model the Klarus XT20, which utilizes the XT20 head. The unit includes a battery pack (4*18650 batteries and charger) and remote control switch. The remote switch can be attached to your handlebar grip for full remote control of the BK20. The two head BK20 light is capable to produce a maximum output of 1200 lumens. The BK20 throws a floodlight beam over an impressive distance to give you far-reaching and wide-angle view of what’s ahead. It is one of the most powerful and desirable bicycle lights in the world.

  • The unit is multipurpose, without any changes to the head of the XT20, allows the XT20 head to be attached to the Klarus XT20 body tube to be utilized as a flashlight for exploration, hunting, camping and travel.

Operation:

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.
