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 AR coating reduces the loss of light due to reflections, allowing more light to pass through the lens. Some flashlights with electronic switches have programmable features. They allow users to customize the behavior of the flashlight.
