Lighting for Darkness
Within the darkness of a cave - any light will have a dramatic affect. The issue is - how can we utilise this contrast between the natural environment of cave darkness and the introduction of artificial lighting technology? How much should be lit? And, further, how this can be done with minimal impact on the cave both in the short and long term? This presentation addresses some of the issues confronting those who light caves for public viewing including such issues as lighting for access, lighting for atmosphere and lighting for protection of the cave resource. It deals with practical philosophies for cave lighting emphasising sensible and low(er) cost approaches.
