Underwater lighting is a term used for lights
that can be submersed to illu
minate
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.
