Powered by One 18650 Rechargeable Battery

18650 batteries feature higher energy density and better energy storage properties than regular AA batteries. A single 18650 battery comes with higher capability with less weight and reduced size, making the EC21 ideal for outdoor use.

18650 batteries have longer cycle life and can be recharged by NITECORE UM10/20 using a solar panel.

Utilizes a CREE XP-G2 LED for More Balanced Performance

  • Far-throwing capability - The CREE XP-G2 LED is capable of emitting a smaller, more focused and further reaching hotspot than the XM-L2 LED.
  • Energy Conservative - The CREE XP-G2 LED consumes half the battery power as the XM-L2 LED to illuminate at equal distance, thus achieving longer run time.
  • Prolonged service life - Burn time of up to 50,000 hours

Independent Red Light Illuminations and Direct Access to Red Light

  • Constant illumination
  • Flashing illumination
  • Red flashes in standby mode

Red Light Purposes

  • Red constant illumination preserves the user’s night-adapted vision
  • Red light flashes once per second to serve as a signal light
  • When in standby mode, the red LED flashes once every three seconds to indicate the location of the EC21

Portable Multimeter

Allows the user to know battery power status when on the move.

After battery installation, the red LED will flash to indicate battery voltage accurate to 0.1V.

Direct Access to Ultralow/Turbo

With the EC21 switched off, press and hold the on/off switch for over one second to enter ultralow output (one lumen)

With the EC21 switched off, press and hold the mode switch for over one second to enter turbo output (460 lumens)

Five Brightness Levels

Highly efficient current control circuit for stable brightness at all battery levels

Three Concealed Special Modes

  • 460 Lumen - Turbo
  • 210 Lumen - High
  • 100 Lumen - Medium
  • 20 Lumen - Low
  • 1 Lumen - Ultralow
  • Strobe
  • S.O.S.
  • Location Beacon

Two Lockout Modes

With the light turned on, press and hold both switches for over one second to enter lockout mode, thus preventing accidental activation of the EC21.

Simply loosen the tailcap to cut off power entirely. This mode is recommended when the EC21 is left unused and stored for an extended period of time.

Stainless Steel Titanium-Plated Clip

EC21 also features two-way detachable stainless steel titanium-plated clip for comprehensive applications

Compact yet Extremely Durable

Carved from a piece of CNC machined aerospace grade aluminum alloy

For All Weather Conditions

Waterproof in accordance with IPX-8, two-meter submersible
