Hozelock's LED pond lights are based on the successful design of the current Aquaglow lights so they can either sink to the bottom of the pond, float on the surface or attach to the cascade fountain pump to light up a fountain.Each pond light includes 10 LED's for maximum light output. The three lamp LED light set works off a 12-volt supply for easy DIY installation and uses a mere 2.85 watts, which means the running cost is extremely low.The lights are supplied with a range of different colour lenses.
