Quintessence square Recessed luminaires for compact fluorescent lamps

Arrangement of downlights depends on the design criteria

A regular grid is recommended for uniform, horizontal illumination

The guide value for the grid size (d) is the luminaire height (h) above the working plane

The offset of the luminaire from the wall (a) is recommended to be half the module of the grid (d)

Offset from wall: one third of room height
Luminaire spacing: equal offset from the wall for uniform wallwashing
