Basic operations:
  • Turn on the light at MAX output by pressing the tailcap button until it clicks.
  • Turn on the light at LOW output 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

Toggle SPOT and FLOOD output:
  • Press and hold the side switch for more than one second to switch between spot only LED, flood only LED, and both LED.

Battery charging:
  • Remove the waterproof cover and insert the charging cable to charge the battery. User must turn on the flashlight switch at the tailcap to charge.
    (The flashlight will switch off the LED output during charge automatically until the charging cable is disconnected.)
  • The indicator may start flashing when user plug in the charging cable (without turning on the tailacp switch). Switch on the tailcap switch to start charging and the charging indicator will reflect the current charging level.

Battery Safety Precaution

Ensure the protective circuit on the 18650 batteries has current limitation of higher than 5A. 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 is based on the Kit model excluding batteries
  2. All batteries must have protruding top button.
  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. Energy saving feature reduce the maximum output current from 100% to 85% after 200 seconds at turbo output.
  6. Runtime is measured using three EAGTAC 3500mAh high discharge 18650 li-ion batteries.
  7. Maximum efficiency occurs when input voltage is very close to LED forward voltage.
