Acebeam D20 specifications

Body, materials, weight, colors

The flashlight weighs 128 g. It is generally comfortable to hold for a long time, and it is also easy to carry in pockets or bags. The best flashlight size depends on personal preference. It also depends on intended use and the specific features you want. The aluminium body of the D20 has a reputation for being durable and strong. It offers excellent resistance to impacts, scratches, and corrosion. The HAIII process makes a hard and wear-resistant surface on the aluminum. This makes it more resistant to scratches, abrasions, and impacts. The D20 flashlight is available in black.

System, LED, lens, reflector

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 coating is thin and applied to the lens surface. It cuts reflections and boosts light transmission. Some flashlights with electronic switches have programmable features. They allow users to customize the behavior of the flashlight.

Performance, flux, intensity, throw

With 2700 lm, the D20 flashlight will offer a brighter and more powerful beam of light. The D20 flashlight has 24200 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.

Software, user interface, modes

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. The SOS code starts three short signals. Then, three long signals follow. Finally, there are three short signals again.

Features, battery, protections

The D20 flashlight utilizes 1 x 21700 Li-Ion battery as its power source. The battery indicator prevents surprise power failures. It ensures the flashlight is ready when needed. The D20 cannot charge batteries. You may need an external charger to keep your battery going. This flashlight has built-in low voltage protection (LVP). It prevents damage from over-discharge, so it doesn't need protected cells. The D20 has thermal protection feature. These mechanisms track and regulate the flashlight's temperature as it operates.

Accessories, package contents

The included battery lets you immediately use the flashlight for your desired applications. It saves time and allows you to focus on your tasks or activities. The lanyard of the D20 protects the flashlight from accidental damage. It does this by stopping it from falling or hitting the ground. 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 D20 flashlight 30 seconds after switching on the light. The ANSI/NEMA FL1 2009 Standard is a set of flashlight performance guidelines.
