Photometric efficiency particularly regarding modern office lighting represents a requirement that cannot always be easily met due to, among other things, increased architectural demands. The photometric performance level of the series LUCEO is therefore even more remarkable: the elegant, extremely slim luminaire body alternatively consists of two different optical systems which excel despite minimised cross sections with peak photometric performance and DSE-compliant luminance limitation. LUCEO includes single- and twin-lamp versions with high-efficiency UXP-Technology louvres as well as the single-lamp PerfectPrism suspended luminaires. Louvre luminaires are available for suspended and for surface mounting. LUCEO free-standing luminaires are a stylish completion of the range.
