People know Osram LEDs for their high performance, energy efficiency, and reliability. 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. The TK17 Osram flashlight has a rear switch. Its operation is usually simple and easy to understand.
