  • Tactical forward clicky switch
  • Basic
    • Turn on the light by pressing the tailcap button until it clicks.
    • Twist the head to select between three output levels.
    • To access the lowest 4th level, turn the head to 3rd level, then 2nd level, and then back to 3rd level within one second.
    • You can pre-selected output level before turning on the light.

  • Advanced
    • Cycle through auxiliary modes: tight the head (1st level), and loose the head (3rd level) and then tight the head within one second to enter auxiliary setting. Repeat to cycle through all settings. Turn off the light or loose the head to quit.

    • Switching between regular mode and tactical mode (default): Switch to 2nd output level and turn the flashlight on and off for 20 times.
    • Tail strobe feature (off by default): With this enabled, you can access strobe output at the tailcap switch button . To enable (or disable) this function (disable from factory), switch to 1st level and turn the flashlight on and off 20 times (one second or less between each click). With the tailcap strobe setting enabled, a double press of the switch button (within one second) will activate the strobe output.
    • Energy saving feature (on by default): T25C2 reduces output by 24% after 200 seconds at turbo mode. With this feature turned off, T25C2 reduces output by 8% instead. To toggle this feature, twist the head to 3rd level and turn the flashlight on and off for 20 times. Once setting has been changed, LED will output 3 seconds at 100% (enable), or 1 second at 100% (disable).


Warranty & Maintenance

  • Ten years performance guaranteed warranty
  • Proper maintenance goes a long way to ensure your light to serve in the toughest environment and years to come.
  • Read below to how to keep your T25C2 in top shape.

Battery Safety Precaution

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 loose the tail-cap to reduce the internal pressure and replace all batteries.     Back to top

Flashlight Maintenance

Cleaning: Periodically clean the thread and o-rings with a lint free cloth. Clean the battery contact, signal contact, thread, and body contact (conductive aluminum area) with a lint free cloth. Do not touch or attempt to clean the reflector, as it will scratch the reflective coating permanently

Lubing: Apply a thin coating of EAGTAC silicon-based lubricant to the o-rings (not the machined thread)and use a small drop of Deoxit red cleaner solution (D series) to slightly lube them for better conductivity and smoother mode switching experience.     Back to top

Other battery types runtime

T25C2 allows users to use different type of batteries in standard configuration. With added extension tube, you get extra runtime and extra output at turbo mode with energy saving mode turned off. Below lists the turbo output runtime with different battery types:

w/ energy saving disabled
2xCR123A 0.6hr, 1x18650 1.3hr, 3xCR123A 1.2hr, 3xRCR123A 0.7hr, 4xCR123A 1.6hr, 2x18650 2.5hr

w/ energy saving enabled
2xCR123A 1hr, 1x18650 1.8hr, 3xCR123A 1.5hr, 3xRCR123A 0.9hr, 4xCR123A 2.2hr, 2x18650 3.3hr

* Above runtime is tested based on EAGTAC 1500mAh CR123A batteries, EAGTAC 750mAh RCR123A batteries and EAGTAC 3400mAh 18650 batteries.
** 3x(R)CR123A are tested with 3cell extender tube, 4xCR123A and 2x18650 are tested with 4cell extender tube. Top
  1. Weight excluding battery
  2. All batteries must have protruding top button. All rechargeable li-ion batteries (e.g. RCR123A and 18650) should be equipped with internal protection circuit against over-charge,over-discharge, and short circuit.
  3. Uses 3 cells body extender
  4. Uses 4 cells body extender
  5. 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.
  6. Beam output diameter taken at one meter
  7. This measurement is taken with energy saving feature (on by default) and with two CR123A. User can disable or enable this energy saving feature. We recommend leaving this feature on when you are using two CR123A. When using 18650 or three or more CR123A, you can consider turning off the energy saving feature for more output. With this features turned off, T25C2 operates at higher temperature. User can hold the flashlight in the hand to help dispute the heat generated from the LED. Lower the output if you find the flashlight too warm to hold.
  8. Frequency: Standard strobe-100%-10Hz, Disorienting strobe-100%-alter between 15 and 6.5Hz, Flash(Hi)-100%-1.7Hz, Flash(Lo)-4%-0.4Hz
  9. When 18650 li-ion battery falls below 2.9V, the LED will flash once every 30 seconds to remind you that the battery is almost out (li-ion protection ic usually shut down the flashlight around 2.7V). Lowering output brightness will extend the runtime and disable the warning until battery voltage drops below 2.9V again..
