One of the most effective hanging concepts for pendant lighting is varying the drop height within a cluster, rather than hanging every fitting at the same level. Three pendants dropped at slightly different heights, for example around 10 centimetres apart, catch the eye in a way a flat row never will, because the height difference creates depth even when the lights are switched off. This works especially well with a design like the Lighting Direct Aria pendant range, where a staggered drop shows off the individual form of each shade instead of letting them blur into one flat line.
There's a functional reason behind varying height too. A slightly lower pendant directly over the centre of the table gives focused task light for dining, while pendants hung a touch higher on either side spread ambient light further across the room without causing glare at eye level. Get this balance right and the fitting does two jobs at once, task lighting and ambient lighting, rather than just one.
