    • Group 2 (tight head): Strobe(Variable)


  • Basic - Press on the switch button until it clicks to turn on the flashlight. Press the switch again until it clicks to switch off the light.
  • Access output groups 1 & 2 - Tight the head to access group 2 output. Loose the head to access group 1 output.
  • Group 1: Very low - low - med - high - Very low - low - med - high - Strobe(Constant)- Flash(Hi)- S.O.S.(Fast) - Beacon - Flash(Low) - cycle
  • Group 2: MAX - Strobe (Variable) - cycle
  • Switch between output level - With the flashlight on, slightly press the switch and release (within 1s) to switch to the next output.

User define function:
  • Toggle between three sets of output brightness level for "low" and "very low" levels - Toggle this setting starting with head loosen, turn on the light, wait for at least one second, and then repeat tight and loose for three times to enter next brightness set.
  • Define any output level as start-up output level for group 2 (loose head). Switch to the desired startup level with head loosen, wait for one second, then tight the head, wait for one second, then repeat loose and tight for three times.

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. Not include battery
  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. At maximum output level (100%), the active thermal management feature slowly reduce the maximum output level according to the flashlight internal tempearture to 50% once flashlight reaches 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 3V 1700mAh CR123A lithium primary battery
  7. Maximum efficiency occurs when input voltage is very close to LED forward voltage.
