Pot lights — what you need to know before installing

Bulbs vs integrated LED, dimming compatibility, and how many you actually need per room.

Pot lights (recessed lights) are the most common lighting upgrade in Ontario homes. Here’s the practical framework before you commit.

Bulbs vs integrated LED

  • Bulb-style (older) — uses a separate GU10 or PAR16 bulb. Easy to swap bulbs when they fail. Limited dimming compatibility, bulbs vary.
  • Integrated LED (modern) — LED is built in. Brighter, more efficient, longer lifespan (25,000+ hours = 20+ years at 4 hr/day). When it fails, replace the whole fixture (rare).

We install integrated LED for almost every job — longer life, better dimming, lower energy use.

How many do you need?

Rule of thumb: one pot light per 16 sq ft of usable floor area for general lighting. So a 12×14 living room (168 sq ft) wants about 10 pot lights. Kitchens with task areas want more.

For accent or wash lighting, you can use fewer.

Standard sizes

  • 4” trim — the modern default. Compact, less obtrusive, plenty of light. Good for new ceilings and most renovations.
  • 6” trim — older standard. Still common in older homes. We can match if you’re replacing one out of many.

Colour temperature

  • 2700K (warm white) — cozy, matches incandescent. Living rooms, bedrooms.
  • 3000K (soft white) — slightly cooler. Hallways, kitchens, dining rooms.
  • 4000K (cool white) — bathrooms, kitchens, work areas.
  • 5000K (daylight) — garages, basements, utility rooms.

Adjustable-CCT fixtures are increasingly popular — pick the temperature via a switch on the back during install. Worth the small premium.

Dimming

Almost all modern integrated LED pot lights are dimmable, but compatibility with your dimmer matters. A Lutron Caséta smart dimmer is the safe choice. Avoid pairing a low-end LED with a cheap dimmer — flicker and buzz are common.

IC vs non-IC

IC-rated (insulation-contact) fixtures can have insulation packed around them — required by code in insulated ceilings. We always install IC-rated.

Wet-rated for bathrooms and outdoor soffits

Bathroom showers and outdoor soffit installs need wet-rated fixtures. Cheaper non-wet fixtures rust out within a couple of years in those locations.
