Operations

Basic operations:
  • Tactical forward clicky switch
  • Basic operation
    • Turn on the light by pressing the tailcap button until it clicks.
    • Twist the head to select between three output levels.
    • Pre-selected output level before turning on the light.
    • Cycle through auxiliary modes: tight the head (1st level), and loose the head (3rd level) and then tight the head within one second to enter auxiliary setting. Repeat to cycle through all settings. Turn off the light or loose the head to quit.
  • Advanced operation
    • Choose one of the four levels as the default medium output: Switch to medium output and turn the flashlight on and off for 20 times to cycle through the next output setting.
    • Choose one of the four levels as the default low output: Switch to low output and turn the flashlight on and off for 20 times to cycle through the next output setting.
    • Tail strobe feature (off by default): With this enabled, you can access strobe output at the tailcap switch button . To toogle this function, switch to 1st level and turn the flashlight on and off 20 times. With the tailcap strobe setting enabled, a double press of the switch button will activate the strobe output.
    Battery charging:8
    • Remove the waterproof cover and insert the included type-c charging cable to charge the battery.
    • During charge, switch on the flashlight switch at the tailcap to charge to 100%. Leaving the switch in off position will only charge the battery to 80% (extend battery life cycle).
    • Blue side LED indicates the battery is being charged. It reports charging percentage by blinking.
    • Time to fully charge a depleted 21700 5000mAh battery is 3-4 hours

Battery Safety Precaution

Ensure the battery has current discharge ability of 10A or higher. 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. This weight measurement includes battery
  2. All batteries must have protruding top button. Protected li-ion battery with 2.5V low voltage cut-off setting is recommended.
  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 measured in a calibrated integrated sphere. This measurement is generally more accurate as it takes into consideration the loss from reflector/lens/bezel.
  5. After 30 seconds at maximum output level (100%), the active thermal management feature will be activated and continuously adjusts the maximum output level according to the flashlight internal tempearture. The adjustment output range is between 60% to 100%. This feature maintains the flashlight surface temperature to be about 140°F (60 °C) (higher surrounding temperaturemay result in higher flashlight 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 one EAGTAC 21700 5000mAh high discharge (10A) li-ion batteries. MAX level runtime includes out-of-current regulation time period when battery is almost depleted. 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. To charge a deeply discharged protected li-ion battery, the flashlight internal charging circuit will use small current to charge the battery. Usually it takes at least a few minutes for the charging circuit to bring the deeply discharged battery voltage to higher than 3.0V (which is the no-load voltage required to disable the over-charge lock-out on the battery protection circuit). If the protected li-ion battery fails to activate, contact our customer services about your situation and we may find other ways to activate it.
