This submersible IP68 luminaire with an LED light source is specially developed to provide good lighting design in underwater applications.

The internal louvre allows the luminaire to be positioned closer to the surface than would have been possible without it, while not causing any glare effect on people standing on the other side of the pool or water feature.
Utilising the asymmetrical grazing beam of 10º x 50º, a continuous lighting effect can be created, like a layer of light through the water.
