Underwater Lighting

Underwater lighting is a term used for lights that can be submersed to illuminate a given area for many different types of reasons. Underwater lighting is used to illuminate otherwise dark and non-visible areas underwater, and is employed for industrial applications where work is to be carried out i.e.: underwater welding of pipes, and other types of submerged fabrications. Underwater lighting is also used for ornamental purposes such as, the illumination of a swimming pool or garden pond and other similar water features. The electrical circuit for underwater lighting can be high or low voltage, and should be installed in accordance with local regulations for electrical safety. Generally the bulbs in underwater lighting equipment are sealed into the unit which will produce a considerable amount of heat, and therefore should remain submerged so the heat can disperse. Underwater lighting equipment must be manufactured from non-corrosive materials, and bronze in particular is material most manufacturers prefer. Underwater lighting can be floating, set into the sides or floor, or even free standing.
