Cree, a US-based LED manufacturing company is a well-regarded LED manufacturer known for its high-quality products and innovation in the lighting industry. Color temperature is a characteristic of light. It is used to quantify the color appearance of light sources, particularly white light. The R20 Javelot has a smooth reflector. The properly focused smooth reflector gives you a more cohesive hotspot and therefore throws better.

The Anti-Reflective coating is a thin optical coating applied to the surface of the lens to minimize reflections and improve light transmission. Mechanical switches are typically built with robust construction, making them resistant to wear and tear, and capable of enduring various environmental conditions. The rear switch allows for quick and easy momentary activation or constant-on activation, enabling rapid response and tactical maneuvering.
