It's important to consider personal comfort and intended use when selecting a flashlight, as a heavier flashlight may be more tiring to hold for extended periods or less suitable for activities that require lightweight portability. The ideal length of a flashlight depends on personal preference, intended use, and the specific features and functionality you're looking for. The aluminium bodies can be anodized, providing a protective layer and a wide range of color options for flashlight bodies. Anodizing enhances the corrosion resistance, hardness, and scratch resistance of the aluminum, while also allowing for a variety of attractive finishes.
HAIII coating is widely used in the flashlight industry due to its durability, corrosion resistance, improved grip, and aesthetic appeal. This flashlight features a captivating black color.
|Emitter||1 x Cree XM-L2 LED, 1x Cree XQE RED LED|

Cree is widely regarded as a reputable LED manufacturer and has a track record of delivering high-quality and innovative lighting solutions. Warm white light is generally considered more comfortable and less harsh on the eyes compared to cool white light. The SD20 features a smooth reflector (SMO). If long-range illumination and throw distance are the primary requirements, a flashlight with a smooth reflector may be more suitable. The AR coating on the lens maximizes light transmission, making the flashlight more effective in darker environments.
The 1000 lm output of SD20 provides greater versatility, as you can adjust the brightness levels to suit different lighting needs. With 7400 cd, the SD20 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 distance refers to the maximum distance at which the flashlight can effectively illuminate an object or target. The stated throw distance typically indicates the point at which the brightness falls below a specified threshold, such as 0.25 lux. Flashlights with a higher cd/lm ratio typically excel in long-range throw and focused beam applications, while flashlights with a lower cd/lm ratio may provide a wider and more evenly distributed beam for closer-range illumination or general-purpose use.
Modes on a flashlight refer to different output settings or levels of brightness that can be selected to suit different needs and preferences.
|Battery||2 x 18650 Li-Ion batteries|
|Protection||depth 100 meters|
The power source of the SD20 flashlight is 2 x 18650 Li-Ion 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 SD20 doesn't have charger port. A charger port is a designated connection point or interface where you can plug in a charger to recharge the flashlight's battery. When the SD20 flashlight detects that the voltage of the battery has dropped to a certain threshold, it automatically reduces or cuts off the power output to prevent further discharge. This helps to preserve the battery's capacity and prevent it from reaching a critically low voltage level. The SD20 has thermal protection feature. The thermal protection mechanisms are designed to monitor and regulate the temperature of the flashlight during operation. This feature helps prevent overheating, which can be detrimental to the flashlight's performance, battery, and overall safety.
|Package contents||conducting plate|
The lanyard of SD20 helps protect the flashlight from accidental damage by preventing it from falling or hitting the ground. When using spare O-rings, it's important to follow the manufacturer's instructions and guidelines for proper installation.
The performance of the Fenix SD20 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.
