Fixture Quantity Calculator
How many downlights, and in what grid? Enter the room's length and width and a target spacing, and this lays them out as neat rows and columns with the offset to keep off the walls.
Roughly ceiling-height-based (~4 ft for a normal room). Use the spacing calculator to set it.
4 across x 3 deep, pitch ~4 x 4 ft.
Suggested grid layout. Start ~2 ft off each wall.
Indicative only. This lays out an even ambient grid; it does not confirm the brightness — check that with the lumen requirement calculator so the room is not over- or under-lit. Avoid a "ceiling of holes" — a good scheme layers task and accent light too, and the wiring is a licensed electrician's job.
