Cost to Install Recessed Lighting in 2026: Per Light and Per Room
Installing recessed lighting in an existing ceiling (without attic access) costs $150 to $350 per light installed by a licensed electrician in 2026. New construction or attic-accessible ceilings run $75 to $150 per light. A full living room with 8 recessed lights typically runs $900 to $2,800 installed. The cost to install recessed lighting depends primarily on whether there is attic access above the ceiling (which eliminates the need to fish wire through walls), the distance from the electrical panel, and whether a new dedicated circuit is needed.
Recessed lighting is the most popular lighting upgrade in US residential renovation. Unlike pendant lights or chandeliers, recessed cans disappear into the ceiling when off and create clean, even illumination when on. The cost varies more than almost any other lighting project based on construction access: a home with an accessible attic allows an electrician to run wire overhead without touching the finished walls, while a home with a finished space above every ceiling requires fishing wire through walls and drilling through plates.
The lighting cost calculator gives you a project total based on room size, ceiling access type, and fixture count.

How Many Recessed Lights Per Room
The general rule is one recessed light per 25 to 30 square feet of ceiling area for general ambient illumination. A 15×20 room (300 sq ft) needs 10 to 12 lights for even coverage. Adjust down if there are other light sources (pendants, floor lamps); adjust up if the room has very dark finishes or vaulted ceilings that absorb or scatter light. The spacing between lights should be roughly 4 feet for 8-inch cans and 3 feet for 6-inch cans; lights placed too far apart create scallop patterns on walls and uneven floor illumination.
For task-specific lighting (kitchen counter illumination, bathroom vanity supplementation), position lights 18 to 24 inches from the wall and space them 18 to 24 inches apart along the counter or vanity run. For accent lighting (artwork, architectural features), use directional recessed fixtures (eyeball or adjustable trims) positioned 18 to 24 inches from the wall, angled 30 to 45 degrees.

LED Wafer Lights vs Traditional Recessed Can
| Feature | LED wafer (ultra-thin) | Traditional recessed can |
|---|---|---|
| Ceiling depth needed | 1/2 to 1 inch | 5 to 9 inches |
| Installation method | Clips into hole; connects to junction box or directly to wire | Can housing mounted to joists; trim inserted from below |
| Retrofit viability | Excellent (works in any ceiling with attic or no attic) | Good with attic access; difficult without |
| IC rating (insulation contact) | Most wafer lights are IC-rated | IC or non-IC versions; must match insulation situation |
| Fixture cost | $15 to $50 per light | $20 to $80 housing + $15 to $60 trim + $10 to $40 LED bulb |
| Replaceability | Full fixture replacement when it fails (non-serviceable) | Only the LED bulb or driver needs replacement |
DIY vs Professional Recessed Lighting Installation
Replacing existing recessed can lights with LED retrofit kits is an accessible DIY project: turn off the circuit, remove the old trim, insert the LED retrofit adapter, twist-connect the wires, clip the LED fixture into the housing, and restore power. No electrical license required for simple fixture replacement on existing circuits. Cost: $20 to $50 per light in retrofit kit material, zero labor cost. DIY saves $30 to $80 per light versus professional fixture replacement.
Adding new recessed lights where none existed involves electrical rough-in work: running new wire from the panel or an existing circuit, cutting holes in the ceiling, installing junction boxes or directly wiring wafer lights, and making all connections. This work requires a permit and licensed electrician in most jurisdictions for new wiring (not just fixture replacement). DIY without a permit on new wiring is illegal and voids homeowner insurance coverage for any resulting fire or electrical incident. Even knowledgeable DIYers who understand the electrical work should pull a permit; the inspection protects both the homeowner and future buyers of the home.
Three Real Recessed Lighting Projects
Example 1: LED wafer lights in a kitchen with no attic access in Boston, Massachusetts
A homeowner installing 10 recessed lights in a 12×16 kitchen with a finished second floor above (no attic access). LED wafer lights selected because they require only 3/4-inch ceiling depth and can be wired directly from hole to hole without a separate junction box for each light. Electrician fished wire from an existing 15-amp kitchen circuit to the first light, then daisy-chained the remaining 9 (within load limits for the circuit). LED wafer fixtures (10): $380. Labor: 6 hours at $110/hour = $660. Permit: $125. Dimmer switch upgrade (replacing existing switch): $45 fixture + $60 labor. Total: $1,270. The electrician patched two small holes where the wire was fished through a wall; the homeowner painted those areas (not included in the quote).
Example 2: Attic-access living room in Denver, Colorado
A homeowner installing 8 recessed lights in a 14×20 living room with full attic access above. Traditional 6-inch IC-rated recessed can housings selected (the attic has blown-in insulation; IC rating is required). Electrician ran a new 15-amp circuit from the panel (existing circuits were fully loaded). New 15-amp circuit from panel to living room: $380. 8 recessed can housings with LED trim: 8 x $65 = $520. Labor (5 hours): $550. Permit: $95. Dimmer switch with remote: $75 fixture + $55 labor. Total: $1,675. The attic access made this project significantly cheaper than it would have been with a finished room above; the electrician ran wire overhead in under 2 hours with no wall penetrations required.
Example 3: Retrofit LED conversion in Phoenix, Arizona
A homeowner DIY-converting existing 16 recessed can lights throughout the house from 65-watt BR30 incandescent bulbs to LED retrofit kits. LED retrofit kits: 16 x $22 = $352. Tools (already owned): $0. Time: 4 hours total. Energy savings: 16 lights x (65W – 8W) x 8 hours/day x $0.16/kWh = $35.39/month. Annual savings: $424.68. Payback on retrofit kit cost: 10 months. This is the most straightforward and highest-ROI electrical upgrade available to a homeowner with existing recessed cans: it requires no permit, no electrician, and pays back in under a year in Phoenix where lights run many hours daily in long summer evenings.

Calculate Lighting Project Cost →Frequently Asked Questions About Recessed Lighting Cost
How much does it cost to install recessed lighting?
Installing recessed lighting in an existing home costs $150 to $350 per light with no attic access, or $75 to $150 per light with attic access above the ceiling. A living room with 8 lights costs $600 to $2,800 professionally installed depending on ceiling access. A new 15-amp circuit from the panel adds $300 to $600 to the project if existing circuits are already loaded. LED retrofit kits for existing can lights cost $20 to $50 per light as a DIY project with no labor cost.
How many recessed lights do I need per room?
A general rule is one 6-inch recessed light per 25 to 30 square feet for general ambient lighting. A 15×20 room (300 sq ft) needs 10 to 12 lights. Kitchens and task areas benefit from tighter spacing (one light per 20 sq ft) and positioning lights directly over work surfaces. Bedrooms need fewer lights than kitchens. Living rooms with multiple supplemental light sources (table lamps, floor lamps) can use fewer recessed lights than a room relying solely on ceiling lighting.
What is the difference between 4-inch and 6-inch recessed lights?
Six-inch recessed lights are the most common size for general room illumination; they produce enough light coverage for a standard residential ceiling height of 8 to 10 feet. Four-inch lights produce less total light output and are typically used for accent or task lighting, or in situations where a smaller fixture is aesthetically preferred. Eight-inch or larger cans are used in commercial applications or very tall residential ceilings. For most residential general illumination applications, 6-inch lights at standard spacing produce the best result.
Do recessed lights need to be on a dedicated circuit?
Recessed lights do not require a dedicated circuit unless their total wattage would overload a shared circuit. A 15-amp circuit at 120 volts handles 1,800 watts continuously. Modern LED recessed lights draw 8 to 15 watts each; 10 LED lights total 80 to 150 watts, well within a 15-amp circuit shared with other loads. If the existing circuit is already fully loaded (check by adding all devices on the circuit), a new circuit is required. An electrician should verify the existing circuit capacity before adding lights to it.
What is IC-rated recessed lighting?
IC (Insulation Contact) rated fixtures can be covered with or in direct contact with attic insulation without creating a fire hazard. Non-IC-rated fixtures require a 3-inch clearance from insulation, which must be maintained with a fire-resistant cover (usually a metal box over the fixture). Any recessed light installed in a ceiling with insulation above it must be IC-rated. Most modern LED recessed fixtures are IC-rated; always verify the fixture’s IC rating before installation in an insulated ceiling.
Can I install recessed lighting without an electrician?
For replacing existing fixtures on existing circuits (no new wiring), a homeowner can install LED retrofit kits or replace fixture trims without an electrician in most jurisdictions, with the circuit breaker off during installation. For adding new recessed lights where none existed, new wiring is required; this work requires a permit and licensed electrician in most jurisdictions. The distinction is fixture replacement (legal DIY) versus new electrical rough-in (requires permit and licensed work).
What color temperature should I use for recessed lighting?
Color temperature is measured in Kelvin (K). Warm white (2700K to 3000K) produces the closest light to incandescent; suitable for bedrooms, living rooms, and dining rooms. Neutral white (3500K to 4000K) is slightly cooler and brighter; good for kitchens, bathrooms, and workspaces where task visibility matters. Daylight (5000K to 6500K) is very white and slightly blue; used in garages, workshops, and some commercial applications but can feel harsh in living spaces. Most residential lighting designers recommend 2700K to 3000K for living areas and 3000K to 4000K for kitchens and bathrooms.
Are LED recessed lights worth the cost over halogen?
Yes, categorically. LED recessed lights use 8 to 15 watts versus 50 to 65 watts for equivalent halogen or incandescent. A 10-light room switched from 65-watt BR30 to 8-watt LED saves approximately 570 watts of draw, or about $27 per month at average US electricity rates for 8 hours of daily use. LEDs also last 25,000 to 50,000 hours versus 2,000 to 4,000 hours for halogen, eliminating frequent bulb replacements in hard-to-reach ceilings. Payback on LED retrofit kits is typically under 12 months.
