Planning Your Layout
Proper planning prevents the most common recessed lighting mistakes. The general spacing rule is to divide your ceiling height in half — in an 8-foot ceiling room, place fixtures approximately 4 feet apart. Keep fixtures at least 3 feet from walls to avoid creating harsh shadows. For task areas like kitchen counters, position fixtures 24 inches from the wall to wash light down work surfaces. Create a scaled drawing of your ceiling and mark each fixture location before cutting any holes. Consider furniture placement — you want lights positioned where you need illumination, not necessarily in a rigid grid pattern.
Choosing Fixtures and Trim
Modern recessed lighting has evolved from bulky cans to slim, wafer-style LED fixtures that fit in tight ceiling spaces. Wafer lights are only 0.5 inches thick, making them ideal for ceilings with limited clearance. Choose IC-rated (insulation contact) fixtures for any location near insulation. For wet areas like showers, use fixtures rated for wet locations with sealed gaskets. Trim options include baffle (textured interior that reduces glare), reflector (smooth interior that maximizes light output), and gimbal (adjustable direction for accent lighting). Matte white trim blends with most ceilings.
Installation Considerations
While handy homeowners can install recessed lighting, the project involves electrical work that may require a permit in many jurisdictions. Always turn off power at the breaker and verify with a voltage tester before starting. Plan your wiring route to minimize drywall damage — fishing wire through existing ceilings is manageable with the right tools. Each fixture on a dimmer circuit should be connected in parallel, not series. Use a dimmer switch rated for LED loads, as standard dimmers can cause flickering. If you’re unsure about any electrical connections, hire a licensed electrician.
