On the occasion of the 50th birthday of Tokyo Tower the familiar lighting of this "Grande Dame" was given a new name-"Landmark Light." The makeover featured improved efficiency and energy savings, and a sparkling new dramatic expression called "Diamond Veil." Landmark Light and Diamond Veil have individual identities. They do not appear together; the changeover and switching on and off received detailed consideration. Spectators can enjoy the various veils worn by the "Grande Dame" throughout the year. Diamond Veil uses only about one-half the energy required for previous light-ups.
