Luminus has established a positive reputation as a reliable LED manufacturer. Warm, white light is generally more comfortable. It's also less harsh on the eyes than cool, white light. The TK16 CU SST20's TIR lens is made of a single piece of transparent material. This material is typically acrylic or polycarbonate. Mechanical switches often offer tactile feedback. Users can feel a distinct click or resistance when they press the switch. A simple press or click of the rear switch turns the flashlight on or off. This removes the need for complex button combinations or multi-step processes.
