Q: What are the key features of TK25R?
A:
- Multiple brightness levels for versatile use
- Combined spotlight and floodlight beam for both wide close-range lighting and long-distance illumination
- Multi-LED system includes tactical high beam, wide side light, UV light, red light, red flash, and red-blue flash
- Supports tactical momentary-on, one-touch turbo, and one-touch strobe functions
- USB Type-C fast charging — fully charged in just 1.5 hours
- Dual control with rotary switch and tail switch
Q: What kind of LED is used in TK25R?
A: One Luminus Cree XHP50.3- LED with a lifespan of 50,000 hours. Color temperature: 5700K
Q: What is the working voltage of TK25R?
A: The operating voltage is 3.0V～4.2V.
Q: What kind of battery can be used in TK25R?
A: It is recommended to use a Fenix 21700 Li-ion battery. Other Li-ion batteries are not recommended. As an unmatched battery may cause the flashlight to fail to work normally.
Q: How to prevent accidental activation of the TK25R?
A: To prevent accidental activation, turn the rotary switch to the lock position before placing the flashlight in your bag, or loosen the tail cap to disconnect the battery.
Q: What are the optional accessories for TK25R?
A: A few compatible accessories include the AOT-04 Traffic wand, ALP-20 Quick-pull holster, ALC-03 Flashlight Holder.
Q: Why does the TK25R downshift to a lower mode after being used for a while and the higher mode cannot be selected?
A: There are two reasons:
1. Intelligent Overheat Protection
The flashlight will accumulate a lot of heat when used at high output levels for extended periods. When the light reaches a temperature of 55°C or above, the light will automatically step down a few lumens to reduce the temperature.
2. Low-voltage Warning
When the voltage level drops below the preset level, the flashlight is programmed to downshift to a lower brightness level until the Low mode is reached.
Q: What is APF？
A: The APF (Advanced Pulse-Frequency Transmission System) was developed by Fenix laboratory, a major technology breakthrough of flashlight industry. Allowing the tactical flashlight achieve a higher level of performance:
- Take light to the extreme. Traditional forward switches are limited by current, and it is difficult to achieve brightness above 2000 lumens. In the age of 21700 batteries gradually expanding, 3000 lumens tactical flashlights are almost impossible; while the flashlight using APF technology can.
- Make the functional tail cap simpler. Traditional multi-function tail cap needs to achieve functional through the double-layer body or additional channels; and the flashlight using APF technology offering a strong reliable flashlight in simple structure, we talking about single layer body if specifically.
- Better anti-interference performance. Complex external environments such as strong magnetic fields are easily dealt through stronger anti-interference ability.
Q: Why does the TK25R happen to flicker?
A: The reasons that may cause the light to flicker, shine intermittently or even fail to illuminate:
1. Poor battery level.
Solution: Recharge or replace the battery.
2. The contact or contact point of the battery or flashlight is dirty.
Solution: Clean the contact points with a cotton swab soaked in rubbing alcohol.
