The choice of color temperature depends on the specific lighting application and personal preferences. The orange peel reflector of SP40 is designed to improve the beam characteristics of the flashlight by diffusing the light emitted from the light source.

The AR coating reduces the loss of light due to reflections, allowing more light to pass through the lens. This can increase the overall brightness and efficiency of the SP40 flashlight. The SP40 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.
