CityU inventors have developed an apparatus that can operate with electronic ballasts to drive DC-powered lighting equipment such as LED lamps, halogen lamps and incandescent lamps. Lamps installed with this apparatus do not need to substitute existing electronic ballasts with LED ballasts. The prop.....
