Recessed Lighting Layout Guide: How Many Lights and Where

The difference between a room that glows and a room that glares is layout. Here's the math.

Recessed lighting is the most requested lighting installation Candge Electrics performs in Connecticut homes. Done well, it disappears into the ceiling and makes a room feel bigger. Done poorly, it creates a runway of hot spots. Here's how we plan it.

How many lights?

A simple starting rule: divide ceiling height by two to get the spacing in feet between lights (an 8-foot ceiling → lights about 4 feet apart), and keep the first row half that distance from the walls. For most living rooms and kitchens that works out to one 4-6 inch LED per 25-40 square feet.

Size and type

  • 4-inch canless LED: modern, slim, easy to install in finished ceilings.
  • 6-inch: wider spread, good for larger rooms and higher ceilings.
  • Adjustable/gimbal: for sloped ceilings and accenting art.

Color temperature

2700K feels warm and cozy (living rooms, bedrooms). 3000K is clean but not clinical (kitchens, baths). 4000K+ belongs in garages and workshops. Many LEDs now let you select the temperature at install.

Always dim

An LED-rated dimmer turns one lighting layout into a dozen moods. Smart dimmers add scenes and schedules — see smart home wiring.

Layer it

Recessed lights are ambient light. Add pendants over islands, fixtures over tables, and under-cabinet strips for task light. The combination is what makes a kitchen in Fairfield, Farmington or Cheshire look like a magazine photo.
