In short
How to set suspension heights, row spacing and orientation for suspended linear LED lighting in open-plan offices and double-height spaces.
Suspended linear lighting looks effortless when it is right and awkward when it is not. Most of the difference comes down to three decisions: height, spacing and orientation.
Suspension height
For direct/indirect fittings, the gap to the ceiling matters as much as the height above the desk. Too close and the uplight creates hot spots on the ceiling. Too far and the ceiling stays dim. The right drop depends on the luminaire's uplight optic, so check it against the photometric data for each scheme.
Row spacing
Spacing is set by the target illuminance, the luminaire output and the ceiling height. Aligning rows with desk banks gives a clean, logical ceiling. Continuous runs avoid the "dashed line" look of separate fittings with gaps.
Orientation
Running lines parallel to the main sightline, usually parallel to the windows and along desk rows, reduces glare and reinforces the architecture. Check UGR for the chosen orientation.

How high should suspended linear lights hang?
It depends on ceiling height and the luminaire's optics. Direct/indirect fittings need enough gap to the ceiling for even uplight, so check the drop against photometric data for each scheme.
Should linear lights run parallel to desks?
Usually yes. Running lines parallel to desk rows and main sightlines tends to reduce glare and gives a cleaner ceiling layout.
