Length194.8 mm
Head diameter41.1 mm
Materialaluminium alloy with HAIII hard-anodized finish

Flashlights in weight range of the Stinger 2020 (348.7 g) may have features like extended battery life, intense brightness, or rugged construction for heavy-duty use. It's important to consider the length of the flashlight to ensure it fits comfortably in your desired carrying method. 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.

Hard-Anodized Type III (HAIII) is a specific anodizing process that creates a thicker and harder oxide layer compared to regular anodizing. It involves subjecting the aluminum to a higher voltage and a sulfuric acid bath, resulting in a dense and durable coating. This flashlight features a captivating black color.

The choice of color temperature depends on the specific lighting application and personal preferences. The Stinger 2020 uses a smooth reflector. Unlike the textured surface of an orange peel reflector, a smooth reflector has a polished, mirror-like surface. The AR coating on the lens maximizes light transmission, making the flashlight more effective in darker environments. The Stinger 2020 uses multiple switches. Depending on the placement and design of the switches, a multiple switch configuration can allow for one-handed operation. This is particularly helpful in situations where you need to hold or manipulate objects with one hand while using the flashlight with the other hand.

The Stinger 2020 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. The Stinger 2020 uses a reear switch. Rear switches are commonly found on tactical flashlights designed for law enforcement, military, and self-defense purposes. The rear switch allows for quick and easy momentary activation or constant-on activation, enabling rapid response and tactical maneuvering.

The 2000 lm output of Stinger 2020 provides greater versatility, as you can adjust the brightness levels to suit different lighting needs. The Stinger 2020 flashlight with 25000 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 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.
