Too few pot lights leave dark corners; too many make a room feel like an office. The right number depends on the size of the room, the ceiling height, the fixtures you choose and how you use the space. Here’s how to think about it, room by room.
The basic rule: think spacing, not count
Instead of starting with a number, start with spacing. A common starting point is to space pot lights roughly half the ceiling height apart — so in a room with an 8-foot ceiling, about 4 feet apart — and keep lights about 2 to 3 feet from the walls. Then adjust for the fixture’s beam, brightness and what the room is used for.
Kitchen
Kitchens need the most light. Focus on the work areas: place pot lights over the countertops, slightly forward of the upper cabinets, plus lights over the sink and stove. Pendants over the island add accent light. More in our kitchen pot lights guide.
Living and family rooms
Aim for even, comfortable light across the room, then add accent lights for a fireplace, artwork or TV wall. A dimmer is a must here.
Bedrooms
Bedrooms need less light. A few pot lights around the edges of the room, or over dressers and bedside tables, usually works better than a grid in the centre.
Hallways
Hallways usually need a single line of lights down the centre, spaced evenly so there are no dark patches.
Bathrooms
Plan light over the vanity, the shower or tub, and the main floor area, using wet-rated fixtures where needed. See bathroom lighting.
Basements
Basements have little natural light, so plan for even coverage. Slim LED fixtures suit low ceilings. More in our basement lighting guide.
Don’t forget the details
- Colour temperature: warm white (2700K–3000K) for living spaces, neutral white (around 4000K) for kitchens and workspaces.
- Dimmers: let one layout work for every time of day.
- Obstacles: joists, ductwork and insulation affect where lights can go.
Every home is different, so the best way to get the number right is a layout planned for your actual rooms.
Brightness: lumens matter more than watts
With LED fixtures, the number on the box that matters is lumens, not watts. A typical 4-inch LED pot light gives roughly 600 to 800 lumens, and a 6-inch light gives more. If you choose brighter fixtures, you can use fewer of them; softer fixtures need closer spacing. This is one reason two rooms of the same size can need a different number of lights.
Ceiling height changes the numbers
Light spreads out as it travels, so higher ceilings let each light cover a wider area, but the light reaching the floor is softer. In a room with 9- or 10-foot ceilings, spacing can usually be a little wider than in a basement with a 7-foot ceiling. For sloped or vaulted ceilings, adjustable trims point the light straight down so it still lands where you need it.
Example layouts
- Small bedroom (10 × 11 ft, 8 ft ceiling): often 4 lights placed around the room, or 2 to 4 over the dressers and bedside areas.
- Living room (14 × 16 ft): commonly 6 to 9 lights in an even pattern, plus 1 or 2 accent lights for a fireplace or TV wall.
- Kitchen (12 × 14 ft): usually 6 to 10 lights, focused over the counters, sink and island.
- Hallway (3 × 15 ft): about 3 or 4 lights in a single line.
- Basement rec room (20 × 25 ft, 7 ft ceiling): often 12 to 16 slim LED lights for even coverage.
These are starting points only. Furniture placement, windows, wall colour and how bright you like your home all change the final count.
Zones and switching
In open-concept spaces, the number of lights matters less than how they are switched. Putting the kitchen, dining and living areas on separate dimmers lets you light only the part of the room you are using. It also makes a larger number of lights feel comfortable rather than overwhelming.
Frequently asked questions
Is it better to have more lights on a dimmer or fewer bright ones?
More lights on a dimmer usually give more even light with fewer shadows, and you can always turn them down.
How far should pot lights be from the wall?
About 2 to 3 feet from the wall is a common starting point. Lights used to wash a wall or highlight art are placed closer.
Can I add more pot lights later?
Yes, but it is easier and tidier to plan the full layout once, so wiring and switching are done together.
