The Flat Series comprises round as well as square LED recessed lights with a low installation height of only 30 mm. They are available in three different sizes. The design is based on a minimalist approach and does not need a metal heat sink. The lights provide an output of up to 150 lumens per watt. In addition, a driver as well as a dimming function were integrated into the body. With a UGR value of below 19, the glare-free lighting is easy on the eye.
