The Catherine Wheel becomes an updated take on the classic ceiling rose, but the light can also be fixed to the wall. Using an ordinary compact fluorescent low-energy bulb, which is hidden from view, the light has minimal impact on the environment. It comes in two diameters, 35cm and 40cm, both of which are just 63mm deep. The light is made from standard components to keep production costs down. The shade is a mirrored acrylic disc covered in an intricate pattern that was meticulously worked out on a computer. Jona Hoad
