Apollon from Osram is a diverse, VDU-compliant (UGR19) LED luminaire for electrical contractors who place importance on both an intelligent light concept and many extras. The luminaires have the appearance of homogeneous 'windows of light' that can be grouped together to create light ceilings. Luminous flux was increased by 15% to 4,000 lumens compared to its predecessor model. The luminaire is therefore an efficient and economical replacement not only for 3-lamp but even for 4-lamp 4x18W (T8) and 4x14W (T5) louvre luminaires.
