There is no need to swim in the dark; you can illuminate your swimming pool perfectly well using solar energy instead.
These solar powered lights are very efficient, highly water resistant and they will keep your pool without an extensive electricity bill.
The solar powered lights have solar panels on the top that soak in the sun’s energy during the day time storing it all in internal rechargeable batteries.
During the dark hours the lights then glow, using the energy collected during the day.
These lights are using LED’s with 140 lumens capable of illuminating a space extending out to 1,000′ sq and also work as a thermometer for your pool, with an LCD on the top that shows the water temperature in the pool.
Easy to attach, this solar powered “solar pool light” is available for $180.
