Cost efficient light

Round or square, in the ceiling grid 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 makes it possible to create a world of light - primarily but certainly not exclusively in offices and conference rooms - that is unrivalled in terms of cost efficiency, advanced technology and user-friendliness.

The "cost efficient light" owes its extraordinarily powerful and homogenous light to RZB SIDELITE®technology, which supplies the luminaire body by lateral light inection, generating high-quality light with up to 142 lumens per watt.

Compared to conventional fittings, energy savings of up to 60 percent are possible with the models in this range; even up to 90 percent when used as part of the RZB light control +3 light management system. The round and transparent, round models of the SIDELITE ECO are available as ceiling surface-mounted or pendant luminaires with an impressive diameter of 580 millimetres. The square design is suitable for installation in sawn ceiling openings or as a highly efficient alternative to replace conventional recessed luminaire fittings in the ceiling grid of classic modular ceilings.

The various different models make it easy to select the right luminaire for a specific building or application, providing plenty of planning and budget security.
