Recessed lighting (also called downlights or can lights) gives rooms a clean, modern look with even illumination. But installation costs vary widely depending on how many lights you need, whether existing wiring can be extended, and whether access from above is available. This guide breaks down every cost factor.
⚡ Key Takeaways
- The typical cost to install recessed lighting is $125–$300 per light, including labour.
- Adding new circuits or working in inaccessible ceilings increases costs significantly.
- LED retrofit kits allow much easier installation in existing ceilings — no housing required.
Average Cost to Install Recessed Lighting
The cost per recessed light installed by an electrician typically ranges from $125 to $300, depending on your location, the difficulty of access, and whether new wiring is needed. A full room installation of 6 lights on an existing circuit runs $750–$1,800 on average.
Cost Breakdown by Project Type
New Build or Open Ceiling (Easiest Access)
When ceiling joists and wiring are accessible — during a renovation with ceilings open, or before drywall — recessed light installation is fastest and cheapest. Expect $60–$100 per light in labour, plus materials ($15–$80 per housing and trim depending on type).
Retrofit Into Finished Ceilings with Attic Access
With attic access above the finished ceiling, an electrician can run wiring through the attic space without damaging the ceiling below. This is the most common residential scenario. Labour runs $80–$150 per light.
Retrofit Into Finished Ceilings Without Attic Access
When there’s no attic — for example, a ground floor room with concrete slab above, or a mid-floor room — wiring must be run through the ceiling cavity using flexible drill bits and fish tapes. This takes significantly longer and costs more — $150–$250 per light.
LED Retrofit Kits (Easiest of All)
LED retrofit kits (sometimes called LED downlight converters) are designed to install directly into an existing can housing or ceiling hole with minimal wiring. They’re ideal for replacing old halogen downlights or CFL cans. Installation can be quick and cost $75–$150 per light.
Additional Costs to Factor In
If the room doesn’t have an existing circuit nearby to extend from, you’ll need a new circuit from the panel — typically $300–$600. Adding a dimmer switch costs an additional $80–$150 per switch. If you want recessed lighting on multiple separate dimmer zones, each zone needs its own switch and potentially its own circuit.

How Many Recessed Lights Do I Need?
A common rule of thumb is one recessed light per 4–6 square feet of ceiling area for general illumination, with lights positioned 2–3 feet from walls. A 12×15 foot room (180 sq ft) typically needs 6–8 lights for even coverage. Task lighting in kitchens and offices may need more. Your electrician or a lighting designer can create a layout based on your specific needs.
Types of Recessed Lighting Fixtures
New Construction vs. Remodel Cans
New construction fixtures are designed to be installed before drywall goes up — they mount to ceiling joists. Remodel fixtures are designed for retrofit installation into existing drywall from below, using metal clips that grip the drywall. If you’re upgrading existing lighting, you’ll use remodel fixtures. Always use IC-rated fixtures in insulated ceilings — these are safe for contact with insulation.
Integrated LED vs. Retrofit LED Trim
Modern recessed lighting comes as integrated LED fixtures (the entire fixture is LED, typically $25–$80 each) or traditional can housings with LED retrofit trim kits ($10–$40 for the trim, plus the housing). Integrated LED fixtures cost more upfront but are sealed against air leakage, last 25,000–50,000 hours, and maintain colour quality throughout their life.
How Many Recessed Lights Do You Need?
A common rule of thumb: one 6-inch recessed light per 25 square feet of ceiling area provides adequate general illumination (assuming 8-foot ceilings and approximately 600-lumen bulbs). For a 200 square foot room, that’s 8 fixtures. Adjust for ceiling height — taller ceilings require more fixtures or higher-lumen units.
Electrical Considerations and Code Requirements
Adding recessed lighting involves creating new circuits or adding to existing ones. Modern NEC code (2020) requires AFCI protection on lighting circuits in most rooms. In rooms with no existing ceiling light, an electrician must run new wiring from a suitable circuit, which is the largest variable in the cost estimate. If your home has no attic access above the installation area, the electrician must fish wires through the ceiling — technically more challenging and time-consuming.
Dimmer switches for recessed lighting require LED-compatible dimmer switches ($20–$50 each) and compatible dimmable LED fixtures — not all LEDs are dimmable.
DIY vs. Hiring an Electrician
Installing recessed lighting in a room with existing ceiling access (open attic above) is within the capability of experienced DIYers. In rooms without attic access, or where new circuits are needed from the panel, professional installation is strongly recommended. DIY fixture costs (materials only): $200–$600 for a typical room. Professional installation with a new circuit: $600–$1,500. Professional installation tapping an existing circuit: $400–$800.
Energy Efficiency and Long-Term Savings with Recessed Lighting
While the upfront installation cost of recessed lighting is a significant investment, the long-term energy savings can offset this expense considerably. Recessed fixtures are often paired with energy-efficient LED bulbs, which consume up to 80% less electricity than traditional incandescent lighting. For homeowners in the United States, where average electricity costs range from $0.13 to $0.16 per kilowatt-hour depending on location, switching to LED recessed lighting can result in substantial monthly savings. A typical room with 6–8 recessed lights using LEDs might save $15–$30 per month compared to older lighting technologies. Over a 10-year period, this equates to $1,800–$3,600 in energy costs alone, often exceeding the initial installation investment. Additionally, LED recessed lights have a lifespan of 25,000–50,000 hours, meaning homeowners may not need to replace bulbs for 10+ years. This extended lifespan further reduces maintenance costs and the inconvenience of frequent bulb replacements.
Recessed Lighting in Insulated Ceilings: IC-Rated Fixtures Explained
If your home has insulation in the ceiling—which nearly all modern homes do for energy efficiency—you must use IC-rated recessed fixtures. IC stands for “insulation contact,” and it means the fixture is rated and designed to have insulation touch it directly without creating a fire hazard. If you install a non-IC fixture in an insulated ceiling, the insulation will trap heat around the recessed can, causing temperatures to climb toward the bulb and transformer, eventually melting insulation on the internal wiring and sparking a fire.
The NEC is explicit: NEC Article 410.16(C) requires that recessed luminaires in spaces where thermal insulation is present must be listed and labeled as suitable for insulation contact. Non-IC fixtures are only safe in uninsulated (or vented) ceiling spaces, which are vanishingly rare in residential construction. When shopping for recessed lights, always verify the “IC-rated” label on the fixture or its documentation. The cost difference is minimal—IC-rated cans typically cost $10–$30 more per fixture than standard cans, a worthwhile safety investment.
Additionally, look for “airtight” ratings (sometimes labeled AI or RA) when available. These fixtures seal the ceiling opening to prevent conditioned air from leaking into the attic, improving your home’s energy efficiency. IC-rated fixtures come in a wide variety of styles, trims, and color temperatures, so you don’t sacrifice aesthetics for safety. Installation is identical to standard recessed lights, and the added cost is recouped through improved insulation performance and peace of mind.
Frequently Asked Questions
Is it worth installing recessed lighting?
Recessed lighting is consistently one of the most popular and well-regarded home improvements. It increases perceived ceiling height, provides clean even illumination, and adds resale value. LED recessed lights are also highly energy efficient — a 9W LED replaces a 65W halogen, saving significantly on energy costs over time.
Can I install recessed lighting yourself?
In the US, some homeowners install recessed lighting themselves, particularly in accessible attic scenarios. However, any work involving new wiring or new circuits requires a permit and inspection in most jurisdictions. In the UK, recessed lighting installation involving new wiring is notifiable under Part P.
What size recessed lights should I get?
4-inch lights are good for accent lighting and task areas. 6-inch lights are the most common for general residential illumination. 8-inch lights are used in very large rooms or high ceilings. Most residential installations use 6-inch LED wafer lights or retrofits.
