What size pot lights should I install?

The most popular pot light size for residential installations is 4 inches, which provides excellent light output while maintaining a clean, modern appearance. For most Ottawa homes, 4-inch LED pot lights offer the best balance of brightness, energy efficiency, and aesthetic appeal.

4-inch pot lights are the standard choice for living rooms, bedrooms, hallways, and kitchens. They provide sufficient illumination without overwhelming the ceiling space and work well with standard 8-9 foot ceilings common in Ottawa homes. These lights typically produce 650-900 lumens, which is ideal for general ambient lighting.

6-inch pot lights are better suited for larger spaces like great rooms, vaulted ceilings, or areas where you need more dramatic lighting. They produce significantly more light (1000-1400 lumens) but can look oversized in smaller rooms or with standard ceiling heights. Consider 6-inch lights if your ceilings are 10 feet or higher, or if you're lighting a large open-concept area.

3-inch pot lights work well for accent lighting, highlighting artwork, or in tight spaces like closets or powder rooms. However, they're less common for general room lighting since they don't provide as much illumination.

Spacing considerations are crucial regardless of size. For 4-inch lights, space them 4-6 feet apart for even coverage. For 8-foot ceilings, position them about 2 feet from walls. The total number depends on your room size - a typical 12x12 room needs 6-8 pot lights for adequate illumination.

ESA permit requirements apply when installing new pot light circuits. If you're adding lights to an existing circuit with capacity, no permit is needed for fixture replacement, but new circuits require permits and inspection. Most installations involve running new 14 AWG wire on 15-amp circuits.

Installation costs in Ottawa typically range from $150-250 per pot light, including the fixture, wiring, and installation by a licensed electrician. LED fixtures cost more upfront but last 15-20 years and use 80% less energy than old halogen bulbs.

For the best results, choose dimmable LED pot lights with a color temperature of 2700K-3000K for warm, comfortable lighting. Avoid cheap fixtures that may flicker or fail prematurely.
