12V/24V low voltage power supply, which is used in ground light, is safe and reliable. Inside synchronic digital controller realizes the effects of color changing. Without connecting to outside controller and cords, the synchronic signal trigger function of the inside controller could make lots of ground lights change color at the same time, including flickering, gradual changing, scanning, chasing, running and etc. to satisfy the requirements of lighting in different places. The combination of light and shade draws a colorful city nocturne, breeding a vivid feeling of live and phantasmagoric. LED ground light it novelty lighting and the best choice of city nocturne.
