Operations

  • Turn on the light at MAX output by pressing and holding the on/off switch button
  • Turn on the light at LOWEST (programmable) output by pressing and release the switch button quickly (within 0.5 second)
  • (UPDATED) To program the LOWEST startup output, switch to the desired output level and WITHIN ONE SECOND switch off and on the flashlight for three times. In rare occasion user may experience the absence of lowest output level from a brand new purchase. If this is case, set the programmable startup level once will initialize the memory setting and will take care of this issue once and for all.
  • To turn off the light anytime, press and release the on/off button switch while it is on.
  • To switch between output levels, with the light turned on, press and hold the on/off switch for longer than 0.5 second to switch to next output. Press and hold the switch will cycle between all levels.
  • To access AUX blinking mode, with the light turned on, cycle through at least two sets of regular brightness level to enter

Battery Safety Precaution

Ensure the battery has current discharge ability of 10A or higher. Always use proven EAGTAC batteries for best performance and reliability.

DX3B-M and DX3B-M Pro flashlights are designed to use either unprotected flat-top or button-top battery. Use only EAGTAC li-ion battery with compatiable 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

Warning for using and handling protected li-ion battery

The EAGTAC protected 18350 rechargeable li-ion battery is never designed or intended to be used inside different flashlight model (including EAGTAC and other brand) other than DX3B-M and DX3B-M Pro, e-cigarette, vaporizer, or any other electronical device. Doing so can be very dangerous and it is at your own risk

Never let the battery come into contact with any metal objects as it will short circuiting the battery and may cause fire or explosion. Do not put the battery in the pocket, purse, bag or elsewhere. Always use plastic battery case for transportation or storage and keep away from heat. Always Keep away from children or pets.

Li-ion battery is very sensitive to charging and discharging characteristics and may cause burn or explosion if misused or mishandled. Never discharge this li-ion battery under 2.7V and never charge it over 4.2V. Always discharge and charge the battery with compatible electrical current. Discard any over-discharged battery or any battery with broken outer wrap.

Always charge the battery inside EAGTAC intended flashlight model on a fire-proof surface. Do not modify the battery in any form.

Only use EAGTAC or EAGTAC autherticity verified li-ion battery in this flashlight. EAGTAC and its dealers will not be held responsible or liable for any injury or damage caused by any third party battery, any third party battery charger, or any improper usage or mishandle of its battery and battery charger.     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. 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 70%-100%. This feature maintains the flashlight surface temperature to be about 130°F (54 °C) for W1900 (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 18350 1300mAh li-ion rechargeable battery
  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.
