  • Three hidden auxiliary outputs7
    • Disorienting Strobe/Beacon (1.67Hz)/S.O.S.


Basic operations:
  • Turn on the light at MAX output by pressing the BLACK button switch.
  • Turn on the light at LOWEST (programmable) output by pressing the WHITE button switch
  • To turn off the light anytime, press and release the BLACK button switch.
  • To program the startup output level, switch to the desired output level and continuously pressing and holding the button for three seconds until the side LED turns on.
  • (Flashlight w/ programmable feature) In rare occasion user may experience the absence of lowest output level from a brand new purchase. If this is case, set the programmable startup level once will initialize the memory setting and will take care of this issue once and for all.
  • 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, cycle through at least two cycle of regular output.
  • 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).

  • Remove the waterproof silicon cap and insert the charging power plug to charge.
  • Blue side LED indicates the battery is being charged. It reports charging percentage by blinking.

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. If you find any oxidation on the battery contact or on the flashlight contact, use a sharp tool to scrap it off. Do not touch or attempt to clean the reflector, as it will scratch the reflective coating permanently.     Back to top

  1. Includes batteries
  2. Battery with protruded top must used in this flashlight.
  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 using a calibrated integrated sphere three minutes after turning on the flashlight. For O.T.F. lumen, measurement is taken one minute after turning on the flashlight.
  5. After 60 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 70%-100%. This feature maintains the flashlight surface temperature to be about 130°F (54 °C) for W1900 (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. Uses EAGTAC protected 18650 3500mAh li-ion rechargeable battery
  7. Maximum efficiency occurs when input voltage is very close to LED forward voltage.
  8. 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.
