Q: What kind of LED is used in TK05R?
A: One Luminus OSRAM KW CSLPM1.TG LED with a lifespan of 50,000 hours.
Q: What is the working voltage of TK05R?
A: The operating voltage is 3.0 V-4.2V. Limit operating voltage range: 3.0V to 5.5V.
Q: What kind of battery can be used in TK05R?
A: It is recommended to use a Fenix 18350 Li-ion battery. Other Li-ion batteries are not recommended.
Q: How to prevent accidentally activate the TK05R?
A: Unscrew the light tail, or remove the battery to prevent accidental activation.
Q: Why does the TK05R 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 the 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.
