Pool lights 

Underwater lanterns can be free-standing, floating, fitted into side-niches or set into the floor of a pool. Their effect can be startling: the murky depths of the day becomes an incandescent underworld for the night.

The electric circuit for underwater lighting can high-voltage or low-voltage (12 volt) and must be installed in scrict accordance with local regulations for electrical safety. Since the bulb will be in a sealed compartment, a considerable amount of heat will be accumulated and must be dispersed. It is therefore necessary to ensure that underwater lights remain underwater.Light fittings must be made in a non-corrosive and heat-resistent material. Bronze is very well suited to this purpose.

Coloured lights are available but it is usually better to rely on a source of colour other than lights (eg coloured vegetation or tiles).
