The Ontero EC luminaire family is designed in cooperation with the Munich designer Jens Pattberg. The basic design concept behind the luminaires is the flowing transition from round to angular elements. The luminaire is made from powder-coated die-cast aluminum and has been specially designed to meet the demands of modern LED light sources. Integrated cooling fins facilitate excellent thermal management and therefore they are efficient to run. The luminaire family comprises an actively cooled LED-version that also allows DALI control, a luminaire with passive cooling and a type for metal halide lamps. Three types of reflector are on offer.
