The UC25 is small, compact, and designed for ultra-portability. Consider the length of the flashlight. It should fit comfortably in your chosen way to carry it. The aluminium body of the UC25 has excellent thermal conductivity. This means it can effectively dissipate heat generated by the flashlight's components. HAIII is a specific anodizing process. It creates a thicker and harder oxide layer than regular anodizing. The UC25 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.

The UC25 flashlight has multiple switch options. They can be useful, adding versatility and convenience to using the flashlight. Some flashlights with electronic switches have programmable features. They allow users to customize the behavior of the flashlight. Mechanical switches are usually robust. They resist wear and tear and work in many environments. Rear switches are common on tactical flashlights. Law enforcement, military, and self-defense personnel use them.

With 800 lm, the UC25 flashlight will offer a brighter and more powerful beam of light. The UC25 flashlight has 22500 cd. It can light objects at greater distances. The throw is the 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.

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. It remembers the mode you were using when the light was last turned off. It stays in that mode when you turn it on again. Strobe mode on UC25 flashlight produces a rapid, repeated flashing of light.

The UC25 flashlight utilizes 1 x 18650 Li-Ion battery as its power source. The UC25 flashlight can charge from a USB power source. This source can be a wall adapter, computer, power bank, or car charger. The flashlight detects when the battery's voltage has dropped to a certain level. Then, it reduces or cuts off the power. Flashlights without thermal protection may rely on other design elements to dissipate heat. These elements include heat sinks, fins, or body materials with good thermal conductivity. The "8" in the IPx8 rating means the highest level of protection. It is against water ingress.

Attaching a lanyard to your UC25 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 UC25 flashlight 30 seconds after switching on the light. The ANSI/NEMA FL1 2009 Standard is a set of flashlight performance guidelines.
