Cree LEDs are commonly used in a wide range of lighting applications. Their products are trusted by lighting professionals and have gained a strong reputation for quality and performance. The choice of color temperature depends on the specific lighting application and personal preferences. With the smooth reflector of the D20, the beam tends to have a well-defined hotspot at the center, which provides a concentrated beam of light for long-range applications.
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 D20 has electronic switch. Some flashlights with electronic switches have programmable features that allow users to customize the behavior of the flashlight. This may include setting specific modes, configuring brightness levels, or enabling unique functions according to individual preferences.
With 2700 lm, the D20 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. The D20 flashlight with 24200 cd has an extended throw distance, allowing you to illuminate objects or areas at greater distances. This can be advantageous for outdoor activities, search and rescue operations, or scenarios where long-range visibility is required.
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.
Modes on a flashlight refer to different output settings or levels of brightness that can be selected to suit different needs and preferences. The D20 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. SOS mode of the D20 produces a specific sequence of long and short flashes to signal distress or emergency situations. It is commonly used in outdoor adventures or survival scenarios.
|Battery||1 x 21700 Li-Ion battery|
|Protection||depth 200 meters|
The D20 flashlight utilizes 1 x 21700 Li-Ion battery as its power source. The D20 has a battery indicator. A battery indicator is a feature that provides information about the remaining power level of the flashlight's battery. It helps users monitor the battery status and estimate how much runtime they have left before the battery needs to be recharged or replaced. The D20 cannot charge batteries directly. You may need an external charger to keep your battery going.
LVP (Low Voltage Protection) is designed to protect the battery from being over-discharged, which can lead to reduced battery life or even permanent damage. The built-in thermal control automatically adjusts brightness output to prevent overheating.
|Package contents||18650 adapter|
2 x spare o-rings
21700 battery with microUSB
With an included battery you can immediately use the flashlight for your desired applications, saving time and allowing you to focus on your tasks or activities. The lanyard of D20 helps protect the flashlight from accidental damage by preventing it from falling or hitting the ground. Having spare O-rings allows you to replace them as needed, ensuring that the flashlight maintains its water-tight seal and remains protected from moisture or water ingress.
The performance of the Acebeam D20 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.
