Downlight spacing
How to think about spacing, wall offsets and even coverage when planning a basic downlight layout.
Downlight guides
Learn the planning terms behind a downlight layout before you compare room sizes, fitting output and beam spread in the calculator.
Downlight wall offset
Plan how far downlights should sit from walls, cabinets, hallways and feature surfaces.
Downlights around ceiling fans
Plan fan clearance, blade sweep, symmetry and task zones before placing downlights.
Lumens, lux and beam angle
Understand how light output, target lux and beam spread affect downlight spacing and coverage.

Plan dimmable downlights for comfort, glare control and flexible room moods without overlighting.
Use the Downlight Planner
Test room dimensions, fitting lumens, beam angle and layout assumptions in the planner before refining the setout.
