A shorter flashlight is generally easier to carry in a pocket, bag, or pouch, making it more convenient for everyday use or when you're on the go. The aluminium body of TK11 TAC has excellent thermal conductivity, meaning it can effectively dissipate heat generated by the flashlight's components.

The HAIII coating provides excellent corrosion resistance, protecting the underlying aluminum from exposure to moisture, humidity, and other corrosive elements. The TK11 TAC flashlight is offered in a stylish black color.


EmitterLuminus SST40 LED
Color temperature6500 K
Lenstoughtened AR coated glass
Switchmechanical rear, rotary rear

Luminus LEDs are known for their efficiency, brightness, color accuracy, and long lifespan. The choice of color temperature depends on the specific lighting application and personal preferences. With the smooth reflector, the beam tends to have a well-defined hotspot at the center, which provides a concentrated beam of light for long-range applications. The AR coating reduces the loss of light due to reflections, allowing more light to pass through the lens.

The multiple switch configuration on the TK11 TAC flashlight can be a useful option, providing additional versatility and convenience in operating the flashlight. Mechanical switches are typically built with robust construction, making them resistant to wear and tear, and capable of enduring various environmental conditions. With a rear switch of TK11 TAC flashlight, the operation of the flashlight is often straightforward and easy to grasp.

The TK11 TAC flashlight with 27893 cd has an extended throw distance, allowing you to illuminate objects or areas at greater distances. The throw is the calculated distance in meters at which the flashlight produces a light intensity of 0.25 lux. The candela per lumen (cd/lm) ratio can be used to determine if a flashlight has a spot or flood type beam.


Modes3 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. Mode memory means that the flashlight will remember the mode you were using when the light was last turned off, and when you turn it on again. The TK11 TAC is tactical strobe ready. The strobe light is disorienting to the person it is aimed at which makes it difficult for them to concentrate.


Battery1 x 18650 Li-Ion battery

Impact resistance2 m

The TK11 TAC flashlight utilizes 1 x 18650 Li-Ion battery as its power source. The TK11 TAC cannot charge batteries directly. You may need an external charger to keep your battery going. When the flashlight detects that the voltage of the battery has dropped to a certain threshold, it automatically reduces or cuts off the power output. The TK11 TAC has thermal protection feature. The thermal protection mechanisms are designed to monitor and regulate the temperature of the flashlight during operation.

The "6" in the IP68 rating represents the level of protection against solid objects, specifically dust and foreign particles. The "8" in the IP68 rating indicates the highest level of protection against water ingress. The impact resistance of a flashlight refers to its ability to withstand physical shocks or impacts without being damaged.


Package contentsclip
nylon holster
spare o-ring
