Tender text without leading brand Exclusive LED free-standing luminaire with direct and indirect luminous flux components. The free-standing luminaire, thanks to its optical and technical design features, harmonises with suspended and surface-mounted luminaires that might be used together in the project. For standard-compliant illumination of single and double workstations. The wide range of variants of this family of free-standing luminaires with different networking functionality options enables flexible, effective solutions to lighting requirements in any type of office environment. The luminaire is supplied in 4 parts (head, supporting column, base, connection cable).
