Frequently Asked Questions 1.
Fiber optics are a way of transmitting light through high-quality plastic fibers.
No electricity and virtually no heat are transferred through the fibers. In a swimming pool or spa, that means there is no dangerous electric light source near the water. The light source is in a remote location, and the pool is lit via the plastic fibers. Before fiber optics, a swimming pool was lit with a 120-volt incandescent bulb placed 18 to 24 inches below water level. This meant high voltage energy precariously close to people swimming in the pool.
