The Prism Solar Motion SMD LED Light uses energy generated by the solar panel during the day to operate the light at night. There are three different modes. In the first two modes, it illuminates brightly when detecting motion, with the option for (1) light OFF, or (2) low light ON during off-motion times. The third mode functions as a medium brightness outdoor light, with the motion sensor deactivated. SMD spotlights offer a higher lumen output for a lower energy consumption - making them more powerful and energy efficient than older LED lights. This is because they work on the principle that fewer and larger SMD LEDs produce a greater lumen output. Color: Black. Material: Acrylonitrile Butadiene Styrene (ABS).
