Cold light sources are excited by chemical, electrical, or bio-energy instead of thermal energy. With higher efficiency rates transforming electricity into luminescence than hot sources, the cold alternatives have excellent optical and shining characteristics. The supplies can outlast typical hot cathode tubes since the electrodes lack thermionic emission. The cold light sources come in a variety of light intensities and colour filters to suit any space.
