Each of the seven lamps contained one half a "log" of olive oil. This amount was sufficient for the flames to burn from "morning until evening" even on long winter nights. The wicks were prepared from worn out tunics and turbans of the priests. The lamps of the Menorah were similar to cups. They were not part of the body of the Menorah and were removable to facilitate cleaning.
