摘　　要：The light propagation medium determines the way in which the light is perceived by the observer’s eye.As water is a good transmitter and diffuser,when designing an underwater lighting system there are features in addition to be analyzed,which complement the common considerations for usual artificial lighting systems.The paper aims to present in detail a luminaire calculation method for 4 different types of pools with clear and transparent water(three recreational swimming pools of same size and depth,situated in interior and exterior and one small training interior swimming pool having the size of a quarter of professional competition type).There is a proposed formula for determining the number of floodlights,depending on water surface,immersion depth,average illumination on surface,uniformity,luminous flux of the light source and a water light distribution coefficient.There are highlighted specific variable parameters to be taken into account to meet the visual requirements mentioned in regulations.Depending on the application,visual comfort can be easily disturbed by the changing criteria of ambiance or surroundings,thus diminishing the visual performance.
