Fenix TK26R Reference Manual and SpecificationsUpdated 2 hours ago

The Fenix TK26R is a tri-colored tactical law-enforcement flashlight with white, red, and green light modes. This summary is drawn from the manufacturer's official user manual — see the downloadable PDF reference manual on the product page for complete details.

Warning

  • This flashlight is a high-intensity lighting device capable of causing eye damage to the user or others. Avoid shining the flashlight directly into anyone's eyes.
  • This flashlight will accumulate a lot of heat when used for extended periods, resulting in high temperature of the flashlight shell. Pay attention to safe use to avoid scalding.

  • Digitally regulated circuit for maintaining a stable output
  • Battery level indication and low voltage warning
  • Reverse polarity protection, to protect from improper battery insertion
  • Intelligent protection against high surface temperature
  • Tactical tail switch for instant activation; functional tail switch for output selection and strobe
  • Functional side switch for white, red and green lights switching
  • Made of durable A6061-T6 aluminum
  • Premium type HAIII hard-anodized anti-abrasive finish
  • Toughened ultra-clear glass lens with an anti-reflective coating
  • 5.91" x 1.57" x 1.00" / 150 x 40 x 25.4 mm. Weight: 5.54 oz / 157 g (excluding battery)

Operating Instructions

Switches: the round one is the tactical tail switch, the oval one is the functional tail switch; the functional side switch is for white, red and green lights switching.

On/Off: tap the tactical tail switch to momentarily turn on the light, release and the light will go out. Fully press the tactical tail switch to constantly turn on the light. Press again to turn off the light.

Output Selection: with the light switched on, single click the functional tail switch to cycle through Turbo, Low, Med, and High.

Red and Green Lights: with the light switched on, single click the functional side switch to cycle through Red light and Green light; single click the functional tail switch to turn back to the previously used white light.

Strobe: with the light switched on, press and hold the functional tail switch for 0.8 seconds to activate Strobe; click the functional tail switch and functional side switch to exit Strobe. With the light switched off, fully press the functional tail switch to rapidly enter Strobe; release and the light will go out.

Intelligent Memory Circuit: the light memorizes the last selected brightness level on White light (excluding Strobe). When turned on again the previously used level will be recalled. When the temperature is reduced, Turbo mode can be reselected.

Note: the above specifications are the test results given by Fenix through its laboratory testing using the Fenix ARB-L21-3500 18650 rechargeable Li-ion battery under the temperature of 21±3°C and humidity of 50%-80%. The true performance of this product may vary according to different working environments and the actual batteries used. *The Turbo output is measured in total of runtime including output at reduced levels due to temperature or the protection mechanism in the design.

See the downloadable PDF reference manual for the output-vs-runtime graph from the manufacturer's manual.

Battery Specifications

Non-rechargeable Battery (Lithium)CR123A3.0VCR123A (No charging)

Warning: do not mix batteries of different brands, sizes, capacities, or types. Doing so may cause damage to the flashlight or to the batteries being used. *18650 Li-ion batteries are powerful cells designed for commercial applications and must be treated with caution and handled with care. Only use quality batteries with circuit protection to reduce the potential for combustion or explosion; cell damage or short circuiting are potential risks the user assumes.

Battery Replacement: unscrew the tail cap to insert the battery with the anode side (+) towards the light head, then screw the tail cap back on.

Battery Level Indication

When the light is switched on, the battery level indicator inside the side switch will light up to display the battery status; the indicator will stay on for 3 seconds before it goes off.

  • Green light on: saturated, 100% - 85%.
  • Green light flashes: sufficient, 85% - 50%.
  • Red light on: poor, 50% - 25%.
  • Red light flashes: critical, 25% - 1%.

Note: this only works with a Fenix ARB-L18 Series 18650 rechargeable Li-ion battery.

Low-Voltage Warning

When the voltage level drops below the preset level, the flashlight is programmed to downshift to a lower brightness level until Low output is reached. When this happens in Low output mode, the indicator of the functional side switch will flash red to remind you to recharge or replace the battery. To ensure normal use, the flashlight will not turn off automatically and will work until the battery runs out completely. This only works with a Fenix ARB-L18 Series 18650 rechargeable Li-ion battery.

Charging

  • First switch off the light and plug the USB A socket of the charging cable into an electrical outlet, then connect the USB Type-C socket of the charging cable to the light.
  • The indicator will display red while charging, and will turn green when fully charged.
  • Once charging is completed, be sure to close the anti-dust cover. (The light features inner waterproofing treatment, thus the performance won't compromise even if there is water in the charging port.)

Note: the normal charging time of the included Fenix ARB-L18-3500 rechargeable Li-ion battery is approximately 3 hours from depletion to full charging. Recharge a stored light every four months to maintain optimum performance of the battery. Low output can be turned on/off by functional side switch while charging; there will be no response upon operation of tail switches while charging. If the tactical tail switch is mistakenly operated during charging, unplug the charging cable and press the tactical tail switch to begin charging again.

Intelligent Protection

The light will accumulate a lot of heat when used on Turbo output level for extended periods. When the light reaches a temperature of 65°C or above, the light will automatically step down a few lumens to reduce temperature. When the temperature is reduced, the output will gradually return to the initial level.

Usage and Maintenance

  • Disassembling the sealed head can cause damage to the light and will void the warranty.
  • Fenix recommends using an excellent-quality battery.
  • If the light will not be used for an extended period, remove the battery, or the light could be damaged by electrolyte leakage or battery explosion.
  • Li-ion battery needs to be charged even if the battery is not exhausted; charge immediately when the battery is exhausted; it has no memory effect.
  • Unscrew the tail cap half a turn or take out the battery to prevent accidental activation during storage or transportation.
  • Long-term use can result in O-ring wear; to maintain a proper water seal, replace the ring with an approved spare.
  • Periodic cleaning of the battery contacts improves the lamp's performance, as dirty contacts may cause the lamp to flicker, shine intermittently, or even fail to illuminate — check that the battery needs replacing (ensure it is inserted according to the manufacturer's specifications), or that the contact points are dirty (clean with a cotton swab soaked in rubbing alcohol). If the above methods don't work, contact your authorized distributor.
