NIMBUS DIR/INDIR
Suspended LED luminaire for premium class office lighting with direct/indirect light distribution. The balanced wide indirect radiation throws light reflected from the ceiling back to the room and in combination with downward lighting provides harmonic distribution of brightness within a room space.
Luminaire housing made of 0,6mm sheet steel, white powder coated finish (RAL9003). Upper part of the luminaire made of 1mm aluminium plate, that serves as passive heat sink for employed LED modules.
Increased protection of the optical part against dirt (IP40). Dark Light concept with UGR <16.
NIMBUS DIR/INDIR could be optionally equipped with two independent drivers, thus enabling independent control of direct and indirect part of luminous flux distribution.
