This Intex magnetic LED pool-wall light 28698 will deliver excellent brightness to your above-ground swimming pool. The light uses magnetic technology to create a light system which safely generates low voltage current through the pool's sidewall to a powerful LED light inside and outside the pool. The LED light can be easily moved around the pool's sidewall. If the light becomes separated from magnet, it will automatically float to surface for easy retrieval. This energy-saving LED pool-wall light will be a must have for swimming pools.
