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. The WK20S uses orange peel (OP) textured reflector. The orange peel (OP) reflector is a specific type of reflector commonly used in flashlights. It is named after its distinctive textured surface, which resembles the skin of an orange.
The AR coating of the lens helps to mitigate these reflections by altering the refractive index of the lens surface. The WK20S 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 WK20S flashlight with 22500 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.
