Operations

Basic operations:
  • Turn on the light at MAX output by pressing the BLACK button switch. Turn on the light at LOWEST output by pressing the WHITE button switch
  • To turn off the light anytime, press and release the BLACK button switch.
Spot / Diffuser setting:
  • Press and hold the BLACK button switch and press the white button switch to cycle between i) spot, ii) diffused, and ii) all LED on setting.
Advanced:
  • 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.

    (For example: if you want to turn on the flashlight at the 3rd level, just press and release the white button switch three times from off.)
  • To enter hidden auxiliary levels, press and hold the WHITE button switch for 4 seconds when the flashligh is on.
  • 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).

Warranty

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

Built-in charger safety warning

Only use the integrated built-in charging socket to charge the original EAGTAC 7.4V battery pack. All EAGTAC battery packs are IC protected, sorted, balanced, and tested before shipping to customers. Charging unbalanced third party 7.4V 18650 battery pack, two separate 3.6V/3.7V 18650 cells, or non-rechargeable batteries (e.g. 3V CR123A) may result in battery fire/explosion and flashlight damage.

For backup power, you can purchase additional EAGTAC 7.4V battery pack (choose from R18/R19/R22/R25 for various battery capacity). For emergency, you can also use four primary CR123A or two individual 18650 batteries (w/ protection board), however you should never charge them with the built-in charger (very important).     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 a) includes batteries, b) excludes 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 EAGTAC R25 7.4V 18650 li-ion battery pack.
  7. Maximum efficiency occurs when input voltage is very close to LED forward voltage.
