The Idrout IP65 is a 150mm round recessed downlight and is made from a patented material call DurCoral. This (as opposed to metal or plaster) is totally waterproof and can be easily set into plaster or brickwork (with wallbox, price upon request).
DurCoral is completely impermeable, durable, water resistant and very tough.
The downlight is totally trimless and IP65 makes it ideal for wet areas, like Spas, shower recesses and heavy duty exterior applications, including oceanfronts.
Also available in a round version – Idroround IP65.
