The carclo 20mm triple (3-up) optics are designed to throw light in several specific illumination patterns. Manufactured in lens quality polycarbonate, carclo tir optics have much higher temperature resistance than acrylic optics and carry a ul rating. These one piece optics are tough and impact resistant but precautions should be taken to prevent them from coming in to contact with organic solvents or vapor. The three legs of the optic are design to fit into the holes on the 3-up cree and luxeon leds; adhesive is recommended to secure the legs into the holes.
