Limelight based on Drummonds principle with a lime source and a mirror. The (industial made) limestone is not a cylinder, but a flat stone with a hollow curve in it. The stone is put in the focus point of the mirror. The spotlight was retraved from a ship, where it was used for signalling purposes. (English)
