System and product description
Ecophon Light Coffer can be used for general lighting, for lighting in a special area, or as an aesthetic part of the ceiling. The light coffer with its indirect lighting ,creates an even and harmonious illumination of the room. If coffers are used for general lighting in large rooms with many workstations, they should be supplemented with luminaires around the coffers. Ecophon Light Coffer consists of two different parts, each with different functions.

• Uplight extrusion: White powder coated aluminium extrusion containing the gear tray.

• Acoustic ceiling: Ecophon Focus E tiles and curved coffer panels with Akutex™ FT surface, installed in Ecophon Connect grid system.

This provides good acoustic properties in combination with excellent light diffusion and light reflection.

Light Coffer Isolux Description: The lighting values are an indication of the illumination obtained from a Light Coffer. The values are obtained in a test room with a ceiling height of 3 m and a total area of 100 m², which is big enough to ensure that the reflection from walls is not dominant. The measurements level is 0,85 m above the floor which corresponds to a normal work place. The room has an Ecophon ceiling with 84% light reflectance. The reflectance of the floor is 20% and that of the walls is 50%. The maintenance factor is 0,85.
