Intex LED light uses magnetic technology to create a light system that safely generates low voltage current through the pool's sidewall to a powerful LED light inside and outside the pool. The advanced, energy efficient LED light delivers more brightness to your pool than a conventional 50-watt halogen pool light. , The LED Pool-Wall light is the ultimate in flexibility and can be attached to any sidewall in any location - and be easily moved to different parts of the pool for different lighting effects. If the inner light unit becomes separated from the outer power source, it will automatically float to the surface for easy retrieval. , Beauty, convenience, innovation, performance, and value - all part of the Intex LED Pool-Wall light! , The outside unit transmits power safely and wirelessly to inside the underwater LED where the magnetic technology holds the two parts together.
