This 300 g flashlight is not excessively heavy, but it is noticeably heavier than the average weight for handheld flashlights. The ideal length of a flashlight depends on personal preference, intended use, and the specific features and functionality you're looking for. Aluminium is a lightweight material, which is beneficial for SP36 Anduril flashlight. 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 comes in a sleek black color option.


Emitter4 x Samsung LH351D LEDs
Color temperature5000 K
LensAR coated glass
Switchelectronic side

Samsung LEDs are known for their energy efficiency, enabling significant energy savings compared to traditional lighting sources. The choice of color temperature depends on the specific lighting application and personal preferences. The SP36 Anduril 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 of the lens helps to mitigate these reflections by altering the refractive index of the lens surface. The SP36 Anduril 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.

Throw352 m
CD/LM factor5.49

With 5650 lm, the SP36 Anduril flashlight will provide an exceptionally bright and powerful beam of light. It can illuminate large areas, outdoor spaces, or even act as a temporary spotlight in certain situations. The SP36 Anduril flashlight with 31000 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. The candela per lumen (cd/lm) ratio can be used to determine if a flashlight has a spot or flood type beam. Well-focused spot beams can be over 100 cd/lm, tactical flashlights are typically between 20-100 cd/lm, and work lights are less than 10 cd/lm.

In some cases, a flashlight with a higher CRI may offer a more natural and pleasant viewing experience, as it can better reveal the true colors of the surroundings. This can be advantageous when using a flashlight for extended periods or in situations where visual comfort is desired. With a CRI of 95, the SP36 Anduril flashlight can render colors with exceptional fidelity, capturing even subtle nuances and details in color. This makes it particularly well-suited for applications where precise color discrimination and accurate color reproduction are critical.
