The choice of color temperature depends on the specific lighting application and personal preferences. The orange peel (OP) reflector is a specific type of reflector commonly used in flashlights. The AR coating of the lens helps to mitigate these reflections by altering the refractive index of the lens surface. Some flashlights with electronic switches have programmable features that allow users to customize the behavior of the flashlight.
