Fiber optic cables are the safest kind of lights to use in swimming pool lighting. Contractors install them in pool walls by the hundreds, if not by the thousands. These cables do not actually create the light they emit; they carry it from a remote electrical power source that produces it. Because there is no electrical wiring of any kind present in a fiber optic pool, there is no risk of short circuit or electrical shock.
The nature of the fiber optic cables themselves also allows for a higher level of special effects than you could expect from standard underwater pool lights. The control unit can be programmed to turn the light in each cable either on or off. By manipulating entire groups of cables, along with individual cables in places, multiple geometric shapes, and thousands of color combinations, can be created.
