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 TIR lens makes the LED light collimated. It does this into efficient, well-controlled beams. These beams maximize the usable lumens in the target area. Some flashlights with electronic switches have programmable features. They allow users to customize the behavior of the flashlight.
