Samsung LEDs are energy efficient. They save much energy compared to traditional lights. The color temperature choice depends on the light's use and personal taste. The SP36 Anduril uses a smooth reflector. A smooth reflector is different from an orange peel reflector. It has a polished, mirror-like surface. The AR coating of the lens helps to reduce these reflections. It does this by changing the lens surface's refractive index. Some flashlights with electronic switches have programmable features. They allow users to customize the behavior of the flashlight.
