LEP technology is a type of lighting. It uses a laser diode to excite a phosphor material. The color temperature choice depends on the light's use and personal taste. The coating is thin and applied to the lens surface. It cuts reflections and boosts light transmission. Mechanical switches are usually robust. They resist wear and tear and work in many environments. The rear switch allows for quick and easy momentary or constant-on activation. It enables rapid response and tactical moves.
