Cost efficient light
New MultiLumen - adjustable in 4 power levels for maximum flexibility

Round or square, recessed in the ceiling or suspended: with a design and function offering such a wide range of applications, as well as energy savings of up to 90 percent, this kind of performance deserves a brand new name: from light to cost efficient light.


The SIDELITE ECO range produces - primarily but not exclusively in offices and conference rooms- a world of light that is unrivalled in terms of cost efficiency, advanced technology and user-friendliness. The RZB SIDELITE "cost efficient light" technology produces an exceptionally powerful and uniform light, which supplies the luminaire body by lateral light injection, generating high-quality light with up to 130 lumen per watt. Compared with conventional light sources, energy savings of up to 60 percent are possible with models in this range, even up to 90 percent when used as part of the RZB light control+3 lighting control system. In the round and transparent round version, the SIDELITE ECO is available as a ceiling-mounted or pendant luminaire with an impressive diameter of 580 millimetres. In the square version, it is suitable for installation in ceiling openings or as a highly efficient alternative to recessed grid luminaires fitted with conventional lamps in classic modular ceilings. With so many versions to choose from, it is easy to make the right choice for your property and application and therefore ensure plenty of planning and budget security.
