This 660 g flashlight is quite heavy for a handheld flashlight. Consider the length of the flashlight. It should fit comfortably in your chosen way to carry it. The aluminium body of the K65 has excellent thermal conductivity. This means it can effectively dissipate heat generated by the flashlight's components. Flashlight makers widely use HAIII coating. It is durable, resists corrosion, and improves grip. It also looks good. The K65 flashlight comes in a stylish black color.

Lighting professionals trust Cree LEDs. Cree LEDs have gained a strong reputation for quality and performance. The color temperature choice depends on the light's use and personal taste. The smooth reflector creates a well-defined hotspot at the center. This hotspot provides a concentrated beam for long-range use. The AR coating reduces the loss of light due to reflections, allowing more light to pass through the lens. Some flashlights with electronic switches have programmable features. They allow users to customize the behavior of the flashlight.

A flashlight's modes are different output settings or brightness levels. They can be chosen to meet different needs and preferences. The flashlight has mode memory.

The K65 flashlight utilizes 4 x 18650 Li-Ion batteries as its power source. A battery indicator is a feature. It shows the remaining power level of the flashlight's battery. The K65 cannot charge batteries. You may need an external charger to keep your battery going. The flashlight detects when the battery's voltage has dropped to a certain level. Then, it reduces or cuts off the power. The K65 has thermal protection feature. These mechanisms track and regulate the flashlight's temperature as it operates. The "8" in the IPx8 rating means the highest level of protection. It is against water ingress.

Accessories, package contents

Package contents2 x spare o-rings

nylon holster
spare rubber cover

The holster keeps your flashlight secure. It provides a reliable and easy way to do this when not in use. Attaching a lanyard to your K65 flashlight provides an additional layer of security. It reduces the risk of accidental drops or loss. Instead of searching for matching O-rings, having spare O-rings allows quick fixes.

According to the ANSI/NEMA FL1 Standard, we measure the performance of the K65 flashlight 30 seconds after switching on the light. The ANSI/NEMA FL1 2009 Standard is a set of flashlight performance guidelines.
