People know Luminus LEDs for their efficiency, brightness, color accuracy, and long lifespan. The color temperature choice depends on the light's use and personal taste. The SC31B 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.
