I've had these in my garden (not submerged in water) for 18 months now and still going strong. About to buy some more. Even in the depths of Winter we get light from them well past midnight (Perth).
Excellent submersible lights. Great quality.
Great light. Got it for my garden. Bright and totally waterproof, long cable.
I am excited as I got my solar lights for the pond!!! The light arrived well packed with bubble wrap to protect the box and its contents. Left the lights in the light for a day without turning them on. After a day bright lights :-) Brighter than I expected. Tested in pond, yes waterproof. All great!
Good set of lights for the balcony! Do not have pool) They work well and very bright. Solar panel stays out of the shade.
