Notes
- The spacing rule is ceiling height ÷ 2, which gives 4 ft here. Rounding to whole fixtures moves it to 3.5 × 3.7 ft — mark the ceiling off the real numbers, not the rule.
- 455 lumens per can is the figure to shop by. A 4″ LED downlight typically runs 600–800 lm and a 6″ runs 800–1,200 lm, so you could drop to 4″ cans or dim these down.
- Kitchen is a task space. 35 fc is the general level — countertops, desks and mirrors still need their own light. Ceiling cans alone put the light behind you and your own shadow onto the work.
- Put them on a dimmer. It costs almost nothing at install, and it is the difference between a ceiling that works at dinner and one that works at 11pm.
- Check the joists before marking. A 4 × 7 grid rarely lands clear of framing on the first try, and moving a can 6 inches to miss a joist is invisible once the trim is on.
The grid
Spacing for recessed cans is ceiling height divided by two. A 8 ft ceiling gives 4 ft, which across a 14 × 26 ft room works out to a 4 × 7 grid — 28 lights.
Rounding to whole fixtures moves the real spacing to 3.5 × 3.7 ft. Mark the ceiling off those numbers, not off the rule of thumb. The first row sits 1.8 ft from the wall — half a spacing. Closer and you get a bright band down the wall; further and the corners go dark.
What to buy, not just how many
364 ft² at 35 footcandles needs 12,740 lumens in the room, which is 455 lumens per fixture — around 6 W in LED.
That is the number to shop by, and it is the one most layout calculators leave out. A 4″ LED downlight typically runs 600–800 lm; a 6″ runs 800–1,200 lm.
Before you cut
Find the joists first. A 4 × 7 grid rarely lands clear of framing on the first attempt, and shifting a can six inches to miss a joist is invisible once the trim is on. Put the whole layout on a dimmer while the wiring is open — it costs almost nothing then and cannot be added cheaply later.
