Recessed lights are the most requested lighting upgrade in DMV living rooms, kitchens and basements, and the easiest to get wrong. Too few and the room has dark corners and bright pools. Too many and the ceiling looks like Swiss cheese and the room feels like an office. A few simple rules get the layout right.
THE QUICK MATH
- Spacing: divide the ceiling height by two. An 8-foot ceiling means lights about 4 feet apart; a 10-foot ceiling, about 5 feet.
- From the walls: start about 2 to 3 feet from the wall, roughly half your spacing distance.
- Rough count: about one 4-inch light for every 20–30 square feet for general lighting.
| Room | Typical Count (8 ft ceiling) |
|---|---|
| 12×12 bedroom | 4 lights |
| 12×16 living room | 6 lights |
| 10×12 kitchen (plus task lighting) | 4–6 lights |
| 20×25 basement family room | 12–16 lights |
4-INCH OR 6-INCH?
Modern LED recessed lights are bright enough that 4-inch trims handle most rooms, and they look cleaner on the ceiling. Six-inch lights still make sense for tall ceilings or wide spacing. Ultra-thin “wafer” LEDs need almost no space above the ceiling, which makes them ideal for retrofits and basements with ductwork overhead.
LAYOUT RULES THAT MATTER MORE
- Light what you use. In a kitchen, place lights over the front edge of the counters, not over the middle of the floor, so you're not working in your own shadow.
- Line them up with the room, not the ceiling joists. A grid that's centered on the room and aligned with windows and cabinets looks intentional.
- Avoid the fan. Lights directly beside a ceiling fan create strobe-like flicker as the blades pass.
- Separate zones on separate switches, and put everything on a dimmer. See our guide to LED dimmer problems before choosing one.
- Color temperature: 2700K–3000K for living spaces; 3000K–3500K for kitchens and work areas. Keep it consistent within a room.
WHAT IT COSTS
| Scenario | Typical DMV Cost per Light (Installed) |
|---|---|
| Open ceiling (basement finish, remodel) | $125 – $225 |
| Retrofit into an existing finished ceiling | $175 – $350 |
| Plaster ceilings or difficult attic access | $250 – $450 |
Add the dimmer switch and any ceiling patching and painting. Electrical work is performed by a licensed electrician, with permits where your jurisdiction requires them.
Recessed lights are background light. A room that feels good to be in also has lamps, sconces or a pendant. Plan recessed lighting as one layer, not the whole plan.
