Basic operations:
  • Turn on the light at MAX output by pressing the tailcap button until it clicks.
  • Turn on the light at lowest output (programmable) by holding the side switch button while pressing the tailcap button until it clicks.
  • For momentary on function, slightly press the tailcap button
  • To switch between different brightness levels, press the side button switch w/ flashlight on
  • To enter hidden auxiliary mode, press the side switch to cycle through two sets of standard output level to enter

Advanced operations:
  • Programmable start-up feature: To program the lowest output start-up level to any other level, press the hold the side switch for at least five seconds at other output level to set it as the start-up output level.
  • Tail strobe feature: Turn the flashlight on and off 20 times (one second or less between each click) to toggle this feature. With the tailcap strobe setting enabled, a double press of the switch button (within one second) will activate the strobe output.
  • Remove the waterproof silicon cap, insert the charging power plug, and turn on the flashlight tailcap switch to charge.
  • Blue side LED indicates the battery is being charged. It reports charging percentage by blinking.
  • When charging is done, remove the charging power plug and turn off the flashlight tailcap switch (wait for a few seconds to let the flashlight circuit to reset itself from charging lock-out status to normal status).
  • When forcing the flashlight to start in high output mode using depleted battery, flashlight will blink to warn user that the battery is unable to keep up the high power input demand. User should switch to lower output and charge the battery as soon as possible.

Battery Safety Precaution

Ensure the protective circuit on the battery has current limitation of higher than 10A. 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 with flashlight cold start-up using a calibrated integrated sphere.
  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%-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. Uses EAGTAC protected 18650 3400mAh (10A high discharge) li-ion rechargeable battery. Using EAGTAC 3500mAh with Sanyo GA cell yields approximately 5% to 10% longer runtime depending on level output.
  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.
