The emitter of TK16 CU XPG3 manufactured by Cree, a US-based LED manufacturing company. Cree is a well-regarded LED manufacturer known for its high-quality products and innovation in the lighting industry. Color temperature is a characteristic of light. It is measured in units called Kelvin (K) and is used to quantify the color appearance of light sources, particularly white light. This TIR lens offers flexibility in achieving various beam patterns, from wide-angle illumination to focused spotlights, depending on the specific design of the lens.

The TK16 CU XPG3 has mechanical switch. Mechanical switches often offer tactile feedback, allowing users to feel a distinct click or resistance when the switch is pressed. This feedback helps users confirm that the switch has been activated or deactivated, providing a reassuring sense of control and awareness. The rear switch of TK16 CU XPG3 is typically operated with the thumb or finger, making it easily accessible and convenient to use.

Intensity6250 cd
Throw158 m
CD/LM factor3.47

The 1800 lm output of TK16 CU XPG3 provides greater versatility, as you can adjust the brightness levels to suit different lighting needs. With 6250 cd, the TK16 CU XPG3 flashlight provides a noticeably brighter and more intense beam of light. It can illuminate objects or areas with greater clarity and visibility, even at longer distances. The throw distance refers to the maximum distance at which the flashlight can effectively illuminate an object or target. The stated throw distance typically indicates the point at which the brightness falls below a specified threshold, such as 0.25 lux. Flashlights with a higher cd/lm ratio typically excel in long-range throw and focused beam applications, while flashlights with a lower cd/lm ratio may provide a wider and more evenly distributed beam for closer-range illumination or general-purpose use.


Modes5 modes
Mode memoryyes
Ramping modeno

Modes on a flashlight refer to different output settings or levels of brightness that can be selected to suit different needs and preferences. The TK16 CU XPG3 has mode memory.
