Basic operations:
  • Turn on the light at MAX output by pressing the BLACK button switch. Turn on the light at LOWEST output by pressing the WHITE button switch
  • To turn off the light anytime, press and release the BLACK button switch.
  • For MAX output momentary on, press and hold the BLACK button switch for immediate output.
  • To switch between different brightness levels, press and release the WHITE button switch when the flashligh is on.
  • To enter hidden auxiliary levels, press and hold the WHITE button switch when the flashligh is on.
  • For instant MAX output - at any output level, press and hold the BLACK button switch. Release the button to return to previous level.
  • For instant Strobe output - at any output level (even) off), double press and hold the BLACK button switch. Release the button to return to previous level (or off).
  • The optional switch button located at the tailcap is treated as the secondary BLACK switch button.

Battery Safety Precaution

Ensure the protective circuit on the 18650 batteries has current limitation of higher than 15A. Always use proven EAGTAC batteries for best performance and reliability.

All EAGTAC flashlights are designed to use button-top battery (battery with protruding positive terminal). For rechargeable li-ion battery, use only EAGTAC li-ion battery, or other protected li-ion battery with compatible length and diameter. Before using the battery, check and ensure the battery outer wrapping (the isolating plastic film that wraps around the metal housing of the battery) is complete. Broken battery wrapping may lead to short circuit and damage to the flashlight.

Lithium and Li-ion battery can explode or cause burns if disassembled, shorted, or exposed to high temperature. Do not mix new and used batteries. Do not mix batteries with different brand, capacity, voltage, or install batteries backwards.

NiMH rechargeable battery may release gas during discharge. If you experience an inflated switch boot or find high pressure being built inside the flashlight, switch off the flashlight immediately. Slowly loosen the tail-cap to reduce the internal pressure and replace all batteries.     Back to top

Flashlight Maintenance

Periodically clean the threads and o-rings with a lint free cloth and apply a thin coating of EAGTAC synthetic grease to the o-rings and threads. After prolonged exposure to moisture, the head and batteries should be removed, inspected, and dried. Do not touch or attempt to clean the reflector, as it will scratch the reflective coating permanently.     Back to top

  1. Battery included
  2. All batteries must have protruding top button. When replacing batteries, ensure all batteries are the same model type and has same measuring voltage and capacity.
  3. Beam output diameter taken at one meter
  4. ANSI FL-1 Lumens is a measurement of light output standardized by American National Standards Institute for use with flashlights. This ANSI Lumen measurement is the total overall light output being emitted from the flashlight. This measurement is generally more accurate as it takes into consideration the loss from reflector/lens/bezel. EAGTAC’s ANSI Lumen output is measured with flashlight cold start-up using a calibrated integrated sphere.
  5. After 35 seconds at maximum output level (100%), this feature activates and continuously adjusts the maximum output level according to the flashlight internal tempearture. The adjustment output range is between 30% to 100% and this feature maintains the flashlight surface temperature to be about 140°F (60 °C) or lower depending on surrounding temperature. It's normal for high power flashlight to run hot at MAX level. Reduce the output if the user finds the flashlight too warm to hold.
  6. Runtime is measured using three EAGTAC 3500mAh high discharge 18650 li-ion batteries. With active thermal management feature, runtime in cooler environment will have shorter runtime (higher MAX output) and long runtime in hotter environment (lower MAX output).
  7. Maximum efficiency occurs when input voltage is very close to LED forward voltage.
  8. At 100% output level, it is possible for the LED indicator to flash three times with freshly charged battery. This is normal as the input current draw from a cold startup flashlight is very high (higher input draw from battery = lower underload battery voltage).
  9. The charging board requires the battery to be lower than 4V in order to start charging. User can force the flashlight to charge without this constraint by turning on the flashlight at MAX output (charging circuit will read lower underload voltage).
