Quantum is a downlight with a bell-shaped housing. However, its flange forms visual unity with a suspended ceiling. The heat sink is made of die-cast aluminium while the casing is coated aluminium with an either embossed or golden finish. The contours of the housing contribute to directing the light outward and limit dispersion. Quantum uses an innovative filter system that maximises the clarity of the light beam and the visual comfort. The spotlight is available in a tilting and a rotatable version as well as in four models of different light intensity.
