Updated: Oct 24

Commercial owners are asking one big question this year: How much will potlight installation actually cost me?
With electricity prices rising and Save on Energy rebates favouring high-efficiency fixtures, pot lights have become a popular way to boost light levels while shrinking hydro bills. Yet there is no one-price-fits-all answer. Material grade, ceiling construction, and even the way your electricians reach each junction box can swing the total budget by thousands.
Below is the first section of our data-driven guide. We will walk through every variable that moves the price tag so you can budget with confidence, compare retrofit kits against brand-new LED cans, and identify savings opportunities that most competitor quotes miss. If you need a fast ball-park number, try our free Lighting Rebate Estimator once you finish reading.
What Affects Commercial Potlight Pricing?

Pot light projects live and die on the details. Keep these cost drivers in mind before you pull the trigger:
Fixture Type Retrofit kit versus new LED fixture
Retrofit kits slot into existing cut-outs, reuse wiring, and qualifies for Save on Energy instant rebates. They cost less up front and keep drywall repairs to a minimum. Learn the pros and cons in our full post on retrofit LED pot lights.
New LED fixtures deliver higher lumen output and longer warrantied life but require fresh wiring and fire-rated housings, adding labour hours.
Ceiling Height and Access Method
Standard nine-foot office ceilings let electricians work from a step ladder—quick and inexpensive.
Retail spaces with open twelve-foot decks usually need mobile scaffolds or scissor lifts, adding equipment rental and setup time.
Warehouse mezzanines above twenty feet often require boom lifts, certified lift operators, and longer cable runs, which increase labour costs by thirty percent or more.
Existing Electrical Infrastructure
Older buildings may lack continuous neutral conductors or have derated conduit fill, forcing panel upgrades or new branch circuits.
Projects in post-1990 buildings with dedicated lighting circuits usually avoid these extras, shaving both material and inspection fees.
Lighting Controls and Dimming Protocol
Adding 0-10 V dimming or networked smart controls pushes fixture cost up by eight to fifteen dollars each and requires separate low-voltage runs.
If you plan to integrate advanced controls later, consider our office lighting upgrade service which bundles installation and programming for a single labour line.
Project Scope and Scheduling
A one-night retail refresh demands overtime premiums, whereas a phased install during regular hours can lower labour rates.
Larger orders unlock volume discounts from manufacturers—often ten percent once you pass two hundred fixtures.
Disposal and Environmental Fees
Fluorescent pot light retrofits generate mercury-bearing lamps and ballasts. Proper recycling in Ontario runs about thirty-five cents per unit plus transportation.
New construction skips these fees entirely.
Up next we will crunch average cost per fixture across typical office, retail, and mezzanine scenarios, then compare retrofit return on investment against new installs. Ready for deeper numbers? Stay tuned, or jump ahead to our Lighting Retrofit Savings Calculator to test your own space.
Average Cost per Fixture (Material plus Labour)
Commercial potlight budgets are easier to predict when you break pricing down to a per-fixture basis. The ranges below reflect typical 2025 quotes we see across Ontario. All numbers include material, electrician time, lift rental where needed, and ESA inspection fees.
Ceiling Type & Height | Typical Material per Fixture* | Labour & Equipment | Environmental & Misc.** | Total Before Rebate | Net After Save on Energy Credit† |
Low-bay office (9 ft drop ceiling) | $40 to $70 (retrofit) $70 to $100 (new can) | $30 to $40 (step-ladder access) | $1 recycling fee | $71 to $141 | $56 to $126 |
Retail floor (open deck 20 ft) | $40 to $90 | $55 to $70 (scissor lift) $6 lift-share per unit | $1 recycling fee | $102 to $167 | $87 to $152 |
Warehouse mezzanine (28 ft) | $40 to $90 | $80 to $95 (boom lift & operator) $10 lift-share per unit | $1 recycling fee | $131 to $196 | $116 to $181 |
Why the spread?
Height drives labour. Anything above twelve feet requires scissor or boom lifts plus certified operators, nearly doubling install time.
Fixture spec changes material cost. High-output cans cost more than entry-level retrofit kits but deliver higher lux levels that meet CSA Z317.49 lighting standards in industrial aisles.
Volume discounts apply. Orders above two hundred units often secure ten percent off list price, a saving we pass straight to clients through our Commercial Lighting Upgrade service.
Quick tip: Use our Lighting Load Estimator to project the kWh reduction from each scenario and check how fast the energy savings offset the install cost.
In the next section we will compare retrofit kits to full replacements in terms of payback period and long-run maintenance. If you have open plenum ceilings or mixed fixture types, jump ahead to our detailed guide on LED retrofit versus new fixture decisions.
Retrofit vs New Installation — Cost and Return on Investment
Pot lights generally fall into two upgrade paths: sliding a retrofit kit into the existing cut-out or installing an entirely new LED can. The upfront cost difference is easy to see, but the smarter question is Which choice pays you back faster?
Decision Factor | Retrofit Kit | New LED Can |
Material + labour | $70–105 per unit installed (see office and retail rows above) | $95–165 per unit installed |
Save on Energy credit | Yes — same $15 per fixture | Yes — same $15 per fixture |
Energy use (15 yr life) | 15 W × 4 000 hours per year = 60 kWh | 18 W × 4 000 hours per year = 72 kWh |
Annual hydro cost (0.14 $/kWh) | $8.40 | $10.08 |
Simple payback window* | 1.4 – 2.3 years | 2.0 – 3.1 years |
*Assumes retrofit replaces a 32 W CFL and new install replaces an older 50 W metal-halide can. Values reflect mid-range pricing from our cost table above.
When a retrofit wins
Drywall stays intact. The kit reuses the existing housing so no cutting, mudding, or paint touch-ups.
Fastest payback. Lower wattage and labour keep the upfront spend low. Most offices see full cost recovery in under two years.
Minimal disruption. Electricians can swap fixtures after hours without relocating staff or retail displays.
Eligible ceilings. Nine-foot T-bar tiles and gypsum soffits where the existing housing is already fire rated.
If this profile matches your space, benchmark your own numbers with our Lighting Retrofit Savings Calculator then read the decision checklist in LED Retrofit vs New LED Fixture: When to Retrofit and When to Replace.
When a new LED fixture pulls ahead
You need more lumens. Retail aisles and showrooms often demand higher foot-candle targets than a retrofit module can hit.
Fire rating or insulation contact. In older wood-frame buildings, new cans with IC-rated housings keep inspectors happy.
Extended warranty periods. Commercial-grade cans often ship with ten-year parts and labour coverage.
Future smart controls. Built-in drivers make networked dimming and daylight sensors plug-and-play.
Planning a full tear-out or major renovation? Our commercial lighting upgrade service wraps design, supply, install, and rebate filing into one turnkey contract so you avoid back-and-forth between trades.
Rebate Opportunities That Cut Your Pot-Light Budget
Ontario’s Save on Energy programs slash the up-front price of LED pot lights as well as the payback period. As of July 2025 most lighting measures have moved to the Instant Discounts Program, which means you receive the dollars right at the distributor counter with zero paperwork — a welcome change from the old prescriptive forms.
Program | Eligible Item | Maximum Discount* | How to Claim |
Instant Discounts | LED recessed downlight (any wattage under 40 W) | Up to $7 per fixture | Buy from a participating distributor and provide your business address. Discount is taken off the invoice on the spot. |
Instant Discounts | Lighting controls such as occupancy sensors or integrated networked drivers | Up to $30 per device | Combine controls with your pot-light order to unlock extra savings. |
Retrofit Custom | Any measure that saves ≥ 50 000 kWh a year (for example, large-scale pot-light plus high-bay overhaul) | $0.20 per lifetime kWh saved or $1 800 per kW reduced, whichever is higher, up to 50 percent of project cost | Submit a pre-approval application before purchase; funds are reserved once the IESO signs off. |
* Actual discount may vary by distributor and product model. Always confirm stock and pricing before issuing a purchase order.
Three quick ways to lock in every dollar
Get pre-approval for Custom early. If your project might cross the Custom energy threshold, file the application before ordering fixtures so the incentive is guaranteed in writing.
Bundle controls with fixtures. The extra $30 per control can shave another five to ten percent off labour-heavy installs where electricians are already running low-voltage cable.
Use automated calculators first. Our free Lighting Rebate Estimator plugs your fixture counts into the latest Instant Discount tables so you know the credit before you even call a supplier. For step-by-step paperwork tips see our 2025 Save on Energy rebates guide.
Example: A sixty-fixture office retrofit qualifies for 60 × $7 = $420 instantly plus 60 × $30 = $1 800 if you add networked sensors. That $2 220 rebate trims the payback on your lighting investment by roughly four months at current hydro rates.
Ready to collect those dollars? LumaEnergy’s turnkey office lighting upgrade service bundles fixture supply, install, and all rebate paperwork so the incentive lands in your pocket without extra admin time.
Hidden Costs That Sneak onto the Final Invoice
Pot-light quotes often spotlight fixture and labour lines but bury smaller charges that still punch your budget. Keep these items on your radar so there are no surprises when the last electrician rolls up the lift.
Waste Disposal and Recycling
Mercury lamps and ballasts from old CFL cans must be recycled at a certified facility. Most haulers charge about thirty-five cents per unit plus a pick-up fee.
Cardboard and plastic pallet wrap add modest transfer-station fees if your building lacks a waste contract.
Tip: Ask suppliers to deliver fixtures unpackaged on reusable totes; it trims waste and labour.
Advanced Controls and Commissioning
Occupancy sensors and networked drivers qualify for extra Save on Energy dollars, but they also need programming and a functional test. Budget twenty to thirty minutes of tech time per zone, plus a return visit if settings change after move-in.
Cloud-based systems sometimes carry annual software licences. Verify subscription terms up front or choose a one-time-fee platform. Our smart lighting controls service bundles first-year commissioning so you are covered.
Ceiling Repairs and Paint Touch-Ups
Swapping larger incandescent cans for smaller LED apertures leaves a visible ring that needs patching.
Water-stained acoustic tiles rarely survive lift traffic; factor in a box of replacements for every fifty fixtures.
Gypsum ceilings over fifteen feet often require a painter on standby because joint compound flashing shows under high-bay light levels.
Lift Rental, Delivery, and Operator Premiums

Quotes may list the daily lift rate but omit delivery, fuel surcharges, and mandatory operator certification.
Weekend or night installs can trigger overtime on both the lift and electrical crew. Confirm exact working hours when negotiating price.
Electrical Permit and ESA Re-Inspection Fees
The Electrical Safety Authority usually waives minor fixture-swap permits inside office ceilings, but new branch circuits or emergency lighting require inspection. Budget $200 to $600 depending on project size and municipality.
A failed first inspection means a re-visit fee. Hiring a licensed electrical contractor like LumaEnergy keeps documentation tight and avoids re-work.
Fire-Stoppage and Insulation Barriers
In wood-frame or mixed-use buildings, fire-rated putty pads and insulation contact (IC-rated) housings add five to twelve dollars per fixture.
Skip them and your building inspector will red-tag the job, forcing costly retrofits later.
Quick checkpoint: Compare your quote line-by-line with this list. If you do not see disposal, lift delivery, or ESA inspection fees, they will likely appear as change orders down the road.

Case Study: Hamilton Office Retrofit Achieving Payback in Under Three Years
A recent Hamilton office retrofit (completed July 2025) shows how a mixed-fixture approach can hit a sub-three-year payback when you combine deeper wattage cuts, longer run-time, and the latest Instant Discounts.
Fixture Type | Before | After | Count | Watts Each (Before → After) | Annual Hours* | kWh Saved per Year |
Pot lights (corridors, lobby) | 42 W halogen cans | 12 W LED retrofit kits | 78 | 42 → 12 | 4 800 | 11 232 |
Flat panels (open office) | 96 W T8 troffers | 35 W LED edge-lit panels | 42 | 96 → 35 | 4 800 | 12 230 |
Totals | — | — | 120 | — | — | 23 462 kWh |
*The tenant runs an extended 13-hour day (7 a.m.–8 p.m.), six days a week.
Project cost breakdown (after Instant Discounts applied)
Pot-light retrofits: 78 × $58 = $4 524
Flat-panel installs: 42 × $138 = $5 796
Networked sensors (one per zone): 18 × $60 = $1 080
Lift rental, disposal, ESA permit: $650
Total outlay: $12 050
Annual savings
Energy: 23 462 kWh × $0.18 /kWh = $4 223
Maintenance (lamp & ballast swaps avoided): $1000
Total yearly benefit: $5 223
Simple payback: $12 050 ÷ $5 223 ≈ 2.3 years
Internal rate of return: 28 percent over ten years.
Why this job beats the three-year target
Higher baseline wattage. Swapping 42 W halogens for 12 W LEDs triples the per-fixture savings compared with older CFL examples.
Extended run-time. Retail-style hours add nearly 20 percent more burn-time than a standard office, magnifying kWh reduction.
Full Instant Discount stack. The tenant pulled $7 per downlight and $14 per flat panel off the invoice on the spot, plus $30 per networked sensor.
Aggressive maintenance delta. Halogen relamping every 2 000 hours disappeared—worth roughly $1 000 per year in labour and lamp spend.
If your building has long hours or still burns halogens or T8s, you can expect a similar sub-three-year payback. Use our free Lighting Retrofit Savings Calculator to plug in your own fixture mix, or schedule a Free Lighting Audit and we’ll run the numbers for you.

FAQ: Potlight Installation Cost
How many pot lights does a one-thousand-square-foot office usually need?
A rule of thumb is one recessed downlight for every seventy to eighty square feet when ceilings are nine feet high. That means a one-thousand-square-foot open plan typically calls for twelve to fourteen pot lights around the perimeter plus flat-panel fixtures over workstations. Use the Lighting Load Estimator in our online-tools hub to test different layouts for your own floor plan.
Do I need an ESA permit for a simple pot-light swap?
If your electrician is only replacing existing luminaires on the same branch circuit, the Electrical Safety Authority usually treats the job as maintenance, and no permit is required. Adding new branch wiring or emergency lighting triggers an inspection. Our commercial lighting upgrade service always confirms permit scope before work starts to avoid unexpected fees.
Will Save on Energy rebates still apply if my project mixes pot lights and flat panels?
Yes. The Instant Discounts program pays per qualifying product, so you can claim up to seven dollars for each recessed downlight and up to fourteen dollars for an integral LED troffer on the same invoice. Review the current dollar amounts in our 2025 rebate guide for full details and timing tips.
How long does a commercial-grade LED pot light last?
Most DLC-listed downlights now carry fifty-thousand-hour ratings and ten-year driver warranties. In a corridor that runs three thousand hours per year, that translates to about sixteen years of service without a lamp change.
Can pot lights tie into smart building controls?
Absolutely. Modern downlights ship with integral 0-10 volt or wireless drivers that connect to occupancy sensors, daylight sensors, and BACnet gateways. If you are exploring networked control, read our breakdown of smart lighting controls to see how sensors can cut another fifteen percent off annual energy use.
How quickly can LumaEnergy finish a retrofit after approval?
A typical mid-size office project—one hundred luminaires split between pot lights and panels—takes two to three nights on site. Quotes include lift delivery, waste recycling, and ESA inspection so there are no delays once your materials arrive.
