Luminus has established a positive reputation as a reliable LED manufacturer. Warm white light is generally considered more comfortable and less harsh on the eyes compared to cool white light. The TIR lens of TK16 CU SST20 consists of a single-piece lens made of a transparent material, typically acrylic or polycarbonate. Mechanical switches often offer tactile feedback, allowing users to feel a distinct click or resistance when the switch is pressed. A simple press or click of the rear switch turns the flashlight on or off, eliminating the need for complex button combinations or multi-step processes.
