The streamlined, simple form of the Cylinder pendant downlight means it can be integrated in many different types of architecture. It also provides high visual comfort. The Darklight technology combines the maximum visual comfort with the maximum light output ratio. In their basic form, downlights direct light downwards in narrow or wide beams and can especially be used to produce ambient lighting. The higher a room is and the larger the ceiling, the more anyone looking up is likely to be dazzled by light from the luminaires.

Downlights installed in particularly glare-sensitive areas - for example, over conference tables - should be fitted with reflectors which provide exceptional glare control.
