LumiNova®

A new-generation luminous substance, used to coat hands and numerals. It stores light which it then emits in the dark causing the hands and numerals to glow and continue to be visible. Previously, radium salts were used which, because of their too dangerous radioactive properties, were replaced by Tritium and more recently by Super-LumiNova, a non-radioactive aloxide.
