Acebeam UC15 (UC15) specifications

Rated 4/5 based on 1283 user votes.

The UC15 flashlight enhances safety by illuminating potential hazards and improving visibility in low-light conditions.


Weight39 g
Length66.1 mm
Body diameter29 mm
Head diameter16.3 mm
Dimensions66.1 x 29 x 16.3 mm
Materialaluminium alloy with HAIII hard-anodized finish

This 39 g flashlight would generally be considered lightweight and easy to handle for most people. The ideal length of a flashlight depends on personal preference, intended use, and the specific features and functionality you're looking for. Aluminium body of UC15 is known for its durability and strength. It offers excellent resistance to impacts, scratches, and corrosion, making it suitable for rugged outdoor use or in demanding environments.

The HAIII process produces a hard and wear-resistant surface on the aluminum, making it more resistant to scratches, abrasions, and impacts. This improves the overall durability of the flashlight body. The choice of flashlight body color can be influenced by factors such as intended use, environment, personal style, and functional requirements.

Cree is widely regarded as a reputable LED manufacturer and has a track record of delivering high-quality and innovative lighting solutions. The emitter of UC15 manufactured by Nichia, a Japanese LED manufacturer. Warm white light is generally considered more comfortable and less harsh on the eyes compared to cool white light. The primary function of the smooth reflector (SMO) is to precisely focus and project the light emitted from the light source into a defined beam pattern. The smooth surface allows for greater reflectivity and light concentration, resulting in a more focused and intense beam with a longer throw distance.

This flashlight has an AR coated lens. This Anti-Reflective coating is a thin optical coating applied to the surface of the lens to minimize reflections and improve light transmission. The UC15 has electronic switch. The electronic switches may have a higher likelihood of standby drain compared to mechanical switches since they require a small amount of power for operation.


Flux1000 lm
Intensity2880 cd
Throw107 m
CD/LM factor2.88

With 1000 lm, the UC15 flashlight will offer a brighter and more powerful beam of light. This higher output can be advantageous in various situations where you require enhanced visibility or need to illuminate larger areas. With 2880 cd, the UC15 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 is the calculated distance in meters at which the flashlight produces a light intensity of 0.25 lux. The cd/lm factor (candela-to-lumen ratio) provides information about how concentrated or focused the light output of a light source is. A higher cd/lm ratio indicates that the light is more concentrated in a specific direction, while a lower ratio indicates a more diffused or spread-out light output.


Modes5 modes

Modes on a flashlight refer to different output settings or levels of brightness that can be selected to suit different needs and preferences. The UC15 has mode memory. 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 strobe function on the UC15 flashlight is a feature that produces a rapid and repetitive flashing of light. It is designed to create a disorienting or attention-grabbing effect.

The power source of the UC15 flashlight is 2 x AAA batteries, providing reliable and long-lasting energy for optimal performance. Having a battery indicator on a flashlight is beneficial as it allows users to monitor the battery status and make informed decisions regarding recharging or replacing the battery. It helps prevent unexpected power failures during critical situations and ensures that the flashlight is ready for use when needed.

The UC15 cannot charge batteries directly. You may need an external charger to keep your battery going. A protected battery is recommended as the light itself does not have low voltage protection (LVP). Flashlights without thermal protection may be more susceptible to overheating under extreme conditions, such as prolonged high-output use or exposure to high ambient temperatures. The "5" in the IP54 rating represents the level of protection against solid objects, specifically dust and foreign particles. The IP54 rated flashlight is protected against dust ingress to a limited extent.

Having separate auxiliary LEDs in a flashlight eliminates the need for additional lighting devices or filters. UV light of the UC15 can be utilized for detecting and illuminating certain substances that are not visible under normal light.

When the flashlight is clipped to a suitable location, it can be angled or positioned to provide hands-free illumination.

The performance of the Acebeam UC15 flashlight is measured according to the ANSI / NEMA FL1 Standard 30 seconds after switching the light on. The ANSI/NEMA FL1 2009 Standard is a set of flashlight performance guidelines.
