With a height of only 4 cm, Quad is a particularly flat LED spotlight. However, it puts out a luminous flux of up to 4,000 lumens. In order to attain the flattest possible design, the light package was divided into 15 individual LED light points. They are mounted directly onto a heat sink made of heat-conducting ceramic so that the heat is directly dissipated into the ceramic. The interchangeable lens disks enable the creation of spot and medium flood beam angles.
