Commercial LED Lighting Retrofit Cost in Ontario: 2026 Guide

Quick Answer

Commercial LED lighting retrofit cost in Ontario depends on the fixture count, existing lighting type, ceiling height, access, controls, operating hours, labour complexity, and rebate eligibility.

There is no honest one size fits all price. An office with fluorescent panels will price very differently from a warehouse with high bays or an industrial building with exterior lights and production areas.

A proper estimate should show:

• Upfront project cost

• Expected energy savings

• Maintenance savings

• Rebate or discount potential

• Estimated payback period

Introduction

If you are planning a commercial LED lighting retrofit in Ontario, the real question is not just “How much will the fixtures cost?”

The better question is:

What will the project cost, how much will it save, and how long will it take to pay back?

Lighting retrofit cost changes by building type, fixture condition, operating hours, installation access, and available rebates. That is why Luma Energy reviews the actual site before recommending LED tubes, retrofit kits, new fixtures, high bays, panels, potlights, wall packs, or controls.

What Affects the Cost of a Commercial LED Lighting Retrofit?

A lighting retrofit is not priced by fixture count alone. Fixture count matters, but it is only one part of the project. A proper audit looks at the existing lighting system, the building layout, the installation environment, and the business case.

Main Cost Drivers

Cost factor	Why it matters	Example
Number of fixtures	More fixtures usually means more materials, labour, disposal, and coordination	A small office is simpler than a full office floor with many troffers
Existing fixture type	Fluorescent, HID, metal halide, halogen, and older LED fixtures may need different upgrade methods	Replacing T8 tubes is different from replacing HID high bays
New LED option	LED tubes, retrofit kits, panels, troffers, high bays, wall packs, and downlights all have different labour needs	A tube replacement may be simpler than installing new fixtures
Ceiling height	Higher ceilings often require lifts and extra safety planning	Warehouse high bays usually need more access planning than office panels
Access requirements	Racking, machinery, vehicles, tenants, or production areas can slow down installation	A warehouse aisle may need work scheduled outside operating hours
Wiring condition	Older wiring, failing ballasts, damaged sockets, or unsafe conditions can increase complexity	A ballast bypass may reveal fixture or wiring issues
Controls and sensors	Occupancy sensors, daylight sensors, dimming, and networked controls can improve savings but add setup work	Offices and warehouses often need different control strategies
Operating hours	The more hours lights run, the stronger the savings case usually becomes	A facility running lights all day often has better payback potential
Installation timing	After hours, weekend, or phased work can affect labour planning	Retail and production facilities may need work around business operations
Rebate eligibility	Eligible products may receive upfront discounts, but the rules depend on the product and program	Some products may qualify through participating distributors
Labour complexity	Fixture location, mounting method, ceiling type, and site restrictions all matter	A clean drop ceiling is usually easier than exterior wall mounted fixtures
Disposal	Old lamps, ballasts, and fixtures may need proper removal	Fluorescent lamps and old ballasts should be handled properly

Why Rough Pricing Can Be Misleading

A rough “price per fixture” can miss important parts of the job.

It may not include:

• Lift access

• Controls

• Old wiring issues

• Ballast condition

• Disposal

• After hours labour

• Rebate eligibility

• Light level requirements

That is why a proper lighting audit is important. The audit should answer four questions:

1. What do you currently have?

This includes fixture type, wattage, lamp type, ballast condition, mounting height, and layout.

2. What should replace it?

The right option may be LED tubes, retrofit kits, flat panels, high bays, wall packs, or new fixtures.

3. How much will it save?

Savings depend on wattage reduction, operating hours, hydro cost, controls, and maintenance reduction.

4. Is the project worth doing?

A good estimate should show cost, savings, rebate potential, and payback period.

Best Starting Point by Building Type

If your building is mainly...	Start here
Office space	office lighting upgrade
Retail, clinic, showroom, or mixed commercial space	commercial lighting upgrade
Warehouse, shop, gym, or high ceiling space	LED high bay lighting upgrade
Manufacturing or production facility	industrial lighting upgrade

Commercial LED Retrofit Cost by Building Type

Commercial LED retrofit cost changes by building type. Each space has different lighting needs, access conditions, operating hours, and upgrade priorities.

That is why Luma Energy does not use random generic pricing. Your project estimate should be based on your actual fixture count, existing lighting, access conditions, operating hours, and rebate path.

Cost Drivers by Building Type

Building type	Common existing lighting	Common LED upgrade	Main cost drivers	Best next step
Office	Fluorescent tubes, troffers, panels	LED panels, LED troffers, T8 LED tubes	Fixture count, ceiling layout, controls, tenant schedule, light comfort	Office lighting audit
Retail	Track lighting, potlights, panels, tubes	LED downlights, panels, accent lighting	Appearance, colour quality, layout, after hours installation	Commercial lighting review
Warehouse	HID, metal halide, fluorescent high bays, older LED high bays	UFO or linear LED high bays	Ceiling height, lifts, fixture spacing, racking, operating hours	High bay lighting audit
Industrial facility	High bays, task lighting, exterior lighting	High output LEDs, task lights, controls	Production schedule, safety, access, light levels, maintenance reduction	Industrial lighting audit
Parking or exterior	Wall packs, pole lights, floodlights	LED wall packs, area lights, floodlights, controls	Mounting height, coverage, safety needs, photocells, timers	Outdoor lighting review
Multi use commercial building	Office lights, common area lights, exterior lights, service area lights	Mix of LED panels, tubes, wall packs, potlights, and controls	Different fixture types, phased installation, tenant access, rebate path	Full commercial lighting assessment

Example: Office Building

Office retrofits often involve fluorescent tubes, troffers, or older panels.

Common upgrade options include:

• LED flat panels

• LED troffers

• T8 LED tubes

• Occupancy sensors

• Daylight controls where useful

The main cost drivers are usually fixture count, ceiling layout, tenant schedule, and whether controls are included.

For example, a basic office retrofit may be straightforward if the ceiling grid is clean and fixtures are easy to access.

It becomes more complex if the work has to happen after hours, in occupied spaces, or across multiple tenants.

Example: Warehouse

Warehouse retrofits are usually more access driven.

Common existing lighting includes:

• Metal halide high bays

• HID fixtures

• Fluorescent high bays

• Older LED high bays

Common upgrades include:

• UFO LED high bays

• Linear LED high bays

• Aisle lighting

• Occupancy sensors

• Daylight controls where appropriate

The main cost drivers are ceiling height, lift access, fixture spacing, racking layout, and operating hours.

A warehouse with clear open access is easier to upgrade than one with active racking, equipment, or production zones under the fixtures.

Example: Industrial Facility

Industrial lighting projects need more planning.

The lighting upgrade may include:

• High bays

• Task lighting

• Exterior lights

• Emergency or safety related lighting

• Controls

• Phased installation

The main cost drivers are production schedule, safety requirements, access, light levels, and the need to avoid downtime.

In these buildings, the cheapest fixture is not always the right choice.

The lighting has to support visibility, safety, productivity, and maintenance reduction.

Common Mistakes Businesses Make

Mistake	Why it can cause problems
Choosing only by fixture price	It ignores labour, access, performance, maintenance, and payback
Assuming rebates apply automatically	Eligibility depends on the product, program, distributor, and project type
Replacing lamps without checking sockets or ballasts	Old components can reduce reliability
Ignoring controls	Sensors and controls may improve savings in the right spaces
Not checking light levels	Lower wattage does not automatically mean better lighting
Waiting until lights fail	Emergency replacement usually gives you fewer options

Does Replacing Lamps Cost Less Than Replacing Fixtures?

Sometimes, yes.

Replacing lamps can cost less upfront than replacing full fixtures.

But that does not always make it the best long term option.

The right choice depends on the existing fixture condition, light quality needs, rebate eligibility, labour, maintenance, and how long you plan to use the space.

Main LED Upgrade Options

Option	What it means	When it can make sense	What to watch for
LED tube replacement	Existing fluorescent tubes are replaced with LED tubes	Offices, storage rooms, back rooms, and simple layouts	Ballast condition, socket condition, compatibility, long term reliability
LED retrofit kit	Existing fixture housing stays, but internal components are upgraded	When fixture housings are still in good shape	Labour, compatibility, appearance, performance
New LED fixture	The old fixture is removed and replaced with a new LED fixture	When old fixtures are damaged, outdated, inefficient, or poor quality	Higher upfront cost, but often better long term performance
LED flat panel	Common office ceiling fixture replacement	Offices, clinics, classrooms, commercial spaces	Layout, glare, colour temperature, dimming compatibility
LED high bay	High output fixture for warehouses, gyms, shops, and industrial spaces	High ceilings and large open areas	Mounting height, beam angle, spacing, lift access
LED potlight or downlight	Recessed or surface lighting for commercial interiors	Retail, offices, corridors, lobbies, hospitality spaces	Appearance, beam spread, ceiling condition, dimming

Lamp Replacement

LED tube replacement is often the simplest looking option.

It can work well when:

• Existing fixtures are in good condition

• The layout already works

• Light levels are acceptable

• The goal is a simple energy reduction

• The building has many similar fluorescent fixtures

But it is not always the best choice.

Older fixtures may have poor sockets, yellowed lenses, failing ballasts, damaged housings, or poor light distribution. In those cases, installing new fixtures may be a smarter long term decision.

New Fixture Replacement

New LED fixtures usually cost more upfront than simple lamp replacement.

But they can also offer:

• Better light output

• Better efficiency

• Cleaner appearance

• Lower maintenance

• Better dimming compatibility

• Better control options

• More consistent light quality

This is especially important in customer facing spaces, offices, warehouses, industrial facilities, and buildings where lighting affects safety or productivity.

Simple Decision Table

If your priority is...	Usually consider...
Lowest upfront cost	LED tube replacement
Better appearance	New LED panels, troffers, potlights, or downlights
Better warehouse visibility	New LED high bays
Fewer maintenance issues	New LED fixtures or properly designed retrofit kits
Better control options	New fixtures with compatible sensors or controls
Better long term performance	New fixtures, especially when existing fixtures are old or damaged

The Key Point

The cheapest option today is not always the cheapest option over the life of the building.

A lower upfront cost can become expensive if the lights fail early, produce poor light, require more maintenance, or do not support the way the space is used.

How Rebates Can Reduce Upfront Cost

Ontario lighting rebates can make a commercial LED retrofit more attractive.

But rebates should not be treated as automatic.

Eligibility depends on:

• The lighting product

• The program rules

• The distributor

• The building type

• Whether the project is a retrofit

• Whether the product is installed in Ontario

• Whether the product meets the required efficiency listing

For many standard commercial lighting upgrades, the main rebate path is now Save on Energy Instant Discounts.

How Save on Energy Instant Discounts Work

Save on Energy Instant Discounts are point of sale discounts.

That means the discount is usually applied when eligible lighting products are purchased through a participating distributor.

This is different from the old process where many lighting measures went through the Retrofit Program.

Save on Energy states that most lighting measures moved from the Retrofit Program to Instant Discounts after December 17, 2023.

What Lighting Products May Be Eligible?

Eligible products may include general purpose and specialty lighting products that meet Save on Energy requirements.

According to Save on Energy program requirements, eligible measures include general purpose and specialty ENERGY STAR or DesignLights Consortium qualified lighting products.

Common commercial examples may include:

• LED tubes

• LED panels

• LED troffers

• LED high bays

• LED downlights

• LED wall packs

• LED lighting controls, where eligible

The exact product must be checked before purchase.

Do not assume a fixture qualifies just because it is LED.

Important Rule for Existing Buildings

For lighting, Save on Energy says Instant Discounts are only available for retrofits in existing buildings where less efficient lighting previously existed.

That matters for Ontario businesses.

If the project is new construction, a new facility, or a new addition, it may not qualify under the lighting Instant Discounts rules. Save on Energy’s 2026 program requirements also state that incented lighting products must not be installed in new construction projects.

What About the Retrofit Program?

Some lighting related projects may still fit the Retrofit Program.

Save on Energy lists network lighting controls under its Retrofit Program prescriptive stream.

It also lists horticulture lighting, horticultural advanced lighting controls, and ventilation equipment under greenhouse incentives. This is why rebate planning should happen early.

A business may have one of these situations:

Project type	Likely rebate path to check
Standard LED lamps or fixtures	Save on Energy Instant Discounts
LED high bays	Save on Energy Instant Discounts, if product and project qualify
LED panels or troffers	Save on Energy Instant Discounts, if product and project qualify
Networked lighting controls	Retrofit Program may apply
Horticultural lighting	Retrofit Program greenhouse incentives may apply
Refrigerated display case LEDs	Program path should be checked before quoting
New construction lighting	Instant Discounts for lighting usually do not apply

Rebate Planning Tips for Ontario Businesses

Confirm Before You Buy

Rebate eligibility should be checked before ordering products.

Once fixtures are purchased or installed, your options may be limited.

Use Participating Distributors

Instant Discounts are delivered through participating distributors.

If the product is not purchased through the right path, the discount may not be applied.

Check the Invoice

Save on Energy program requirements say participating distributors must display the pass through incentive as a line item on the purchaser sales invoice, using “Save on Energy Instant Discounts.”

For contractors, the incentive amount should also be documented to the end customer where applicable. Learn more by reading the SOE's program requirements.

Do Not Double Dip

Save on Energy notes that Retrofit Program participants must not also accept Instant Discounts for the same lighting measures, to avoid duplication of incentives. More info on Save on Energy

What Is the Payback Period for a Commercial LED Lighting Upgrade?

The payback period tells you how long it may take for the lighting upgrade to recover its cost through savings.

For a commercial LED retrofit, payback depends on several factors.

Main Payback Factors

Factor	Why it matters
Current wattage	Higher existing wattage usually creates more savings potential
New LED wattage	Lower wattage can reduce electricity use
Operating hours	More hours usually means faster savings
Hydro rate	Higher electricity cost increases the value of each kWh saved
Maintenance savings	Fewer lamp and ballast replacements can improve the business case
Rebate or discount amount	Incentives can reduce upfront cost
Installation cost	Labour, lifts, access, and controls affect total project cost
Controls	Sensors and dimming can reduce runtime in the right spaces

Simple Payback Formula

You do not need a complicated formula to understand the concept.

The basic idea is:

Project cost after rebates divided by estimated annual savings.

For example:

Item	What it means
Project cost after rebates	What the business pays after eligible discounts or incentives
Estimated annual savings	Electricity savings plus maintenance savings
Payback period	How many years it may take to recover the project cost

The more hours your lights run, the faster the payback usually becomes.

Why Operating Hours Matter So Much

A fixture that runs two hours per day will save less than the same fixture running twelve hours per day.

That is why lighting retrofits often make stronger financial sense in:

• Warehouses

• Manufacturing facilities

• Offices with long operating hours

• Retail stores

• Gyms

• Parking garages

• Exterior security lighting

• Common areas in commercial buildings

Example: Same Fixture, Different Runtime

Space	Runtime pattern	Payback impact
Storage room	Used occasionally	Lower savings potential
Office floor	Used most business days	Moderate savings potential
Warehouse	Runs long hours	Stronger savings potential
Exterior security lighting	Runs overnight	Often strong savings potential
Production facility	Runs extended shifts	Often strong savings potential

Do Controls Improve Payback?

Sometimes, yes. Controls can help reduce wasted runtime.

Common options include:

• Occupancy sensors

• Vacancy sensors

• Daylight sensors

• Dimming controls

• Networked lighting controls

• Timers or photocells for exterior lighting

Controls are most useful where lights are often left on when not needed.

Examples include:

• Storage rooms

• Washrooms

• Private offices

• Boardrooms

• Warehouses with low traffic zones

• Parking areas

• Common areas

• Exterior lighting

But controls should be designed properly.

Poorly placed sensors can frustrate staff, reduce comfort, or create dark zones.

What to Calculate Before Approving a Retrofit

Before moving forward, an Ontario business should estimate:

Existing Lighting Cost

This includes current wattage, fixture count, and operating hours.

New Lighting Cost

This includes proposed wattage, new fixture type, and expected runtime.

Rebate Impact

This includes Save on Energy Instant Discounts or any applicable Retrofit Program path.

Maintenance Reduction

This includes avoided lamp, ballast, lift, and service costs where applicable.

Payback Period

This shows whether the project makes financial sense.

Use Luma Energy’s lighting operating cost calculator and lighting retrofit savings calculator to compare current lighting costs against LED upgrade options.

When Is a Lighting Retrofit Usually Worth It?

A lighting retrofit is usually worth reviewing when the building has older, inefficient, high maintenance, or high use lighting.

It is not only about energy savings.

The project may also improve:

• Visibility

• Safety

• Staff comfort

• Customer experience

• Maintenance planning

• Building appearance

• Operating cost control

Good Candidates for a Commercial LED Retrofit

A retrofit is usually worth investigating if one or more of these apply.

Sign	Why it matters
Lights run many hours per day	More runtime usually creates stronger savings potential
Fluorescent fixtures are still in place	Older fluorescent systems can use more energy and require more maintenance
HID or metal halide fixtures are still in place	These are common retrofit targets in warehouses and industrial buildings
Maintenance is frequent	Replacing lamps, ballasts, and failed fixtures adds cost and disruption
Light levels are poor	Poor visibility can affect safety, comfort, and productivity
Staff complain about lighting	Flicker, glare, dim areas, or harsh colour can affect the work environment
The building has many similar fixtures	Repeated fixture types can make the project easier to standardize
Exterior lights run overnight	Long runtime can create a stronger savings case
A rebate path is available	Incentives can reduce upfront cost
The owner plans to keep the space	Longer use of the building gives more time to benefit from savings

Spaces That Often Save More

Some spaces are naturally better candidates because lights run longer or fixtures are harder to maintain.

Space type	Why it may be a strong candidate
Warehouse	High ceilings, long runtime, high bay fixtures, lift related maintenance
Industrial facility	Long operating hours, safety needs, production visibility
Office	Many repeated fixtures, comfort concerns, control opportunities
Retail	Appearance, operating hours, customer experience
Gym or recreation facility	High ceilings and long lighting schedules
Parking area	Overnight runtime and safety needs
Exterior building lighting	Security, visibility, and long runtime
Common areas	Lights often stay on for extended periods

When a Retrofit May Not Be Worth It

Not every lighting project has a strong payback.

A retrofit may be less attractive if:

• There are very few fixtures

• The lights are rarely used

• A recent LED upgrade was already completed

• The fixtures are mostly decorative

• Energy savings are minimal

• The business is leaving the space soon

• The project is new construction and does not qualify for lighting Instant Discounts

• The existing lighting already performs well

This does not mean you should ignore the lighting.

It means the project should be checked before spending money.

Quick Decision Table

Situation	Likely recommendation
Old fluorescent office lights	Review LED tubes, panels, troffers, and controls
Metal halide warehouse high bays	Review LED high bays and fixture spacing
Exterior wall packs running overnight	Review LED wall packs, photocells, and coverage
Recently upgraded LED fixtures	Check performance before replacing
Low use storage area	Controls may matter more than full replacement
Customer facing retail space	Balance savings with appearance and light quality
Industrial facility with downtime concerns	Plan a phased installation

The Best Rule

A lighting retrofit is worth serious consideration when the savings, maintenance reduction, light quality improvement, and rebate potential are strong enough to justify the project.

That is exactly why a proper audit matters.

Luma Energy can review your fixture count, existing wattage, operating hours, upgrade options, rebate path, and payback period before you decide.

For next steps, start with a commercial lighting upgrade, industrial lighting upgrade, or office lighting upgrade review depending on your building type.

Example Retrofit Scenarios

Every commercial LED retrofit should be priced from the actual building.

Still, examples can help Ontario businesses understand what usually changes from one project to another.

Below are three common retrofit scenarios.

Small Office Retrofit

A small office may still have older fluorescent panels, fluorescent tubes, or aging troffers.

The upgrade may include:

• LED flat panels

• LED troffers

• T8 LED tubes

• Occupancy sensors

• Controls for boardrooms, private offices, washrooms, or storage areas

Common Existing Setup

Area	Common existing lighting	Common issue
Open office	Fluorescent panels or troffers	Flicker, uneven light, old lenses, ballast maintenance
Private offices	Fluorescent tubes or panels	Lights left on when rooms are empty
Boardroom	Fluorescent or older LED panels	Glare, poor dimming, uncomfortable light
Washrooms	Fluorescent tubes or compact fluorescent lamps	Lights left on for long periods
Storage rooms	Fluorescent fixtures	Low use space with wasted runtime

What Usually Affects Cost

The main cost drivers are:

• Number of fixtures

• Ceiling grid condition

• Fixture size

• Controls

• Tenant schedule

• After hours installation

• Existing wiring or ballast condition

Practical Tip

For offices, do not only compare wattage.

Also check:

• Glare

• Colour temperature

• Colour consistency

• Dimming needs

• Occupancy sensor placement

• Staff comfort

Poor lighting can make an office feel dated even if the energy savings look good on paper.

For office projects, start with Luma Energy’s office lighting upgrade service.

Warehouse High Bay Retrofit

Warehouses are often strong candidates for LED upgrades because lights are commonly mounted high, run for long hours, and cost more to maintain.

Older warehouse lighting may include:

• Metal halide high bays

• HID fixtures

• Fluorescent high bays

• Older LED high bays

• Exterior wall packs

• Loading dock lights

The upgrade may include:

• UFO LED high bays

• Linear LED high bays

• Aisle lighting

• Occupancy sensors

• Daylight controls

• LED wall packs

• Exterior security lighting

What Usually Affects Cost

Cost driver	Why it matters
Ceiling height	Higher mounting heights may require lifts and more planning
Racking layout	Aisles, shelves, and product storage affect access and light distribution
Fixture spacing	Poor spacing can cause shadows, dark zones, or overlit areas
Operating hours	Longer runtime usually improves savings potential
Lift access	Equipment access can affect labour time and scheduling
Production or shipping schedule	Work may need to happen outside busy periods
Controls	Sensors may help reduce wasted runtime in low traffic areas

Practical Tip

Do not replace high bays one for one without reviewing layout.

A better LED fixture may allow different spacing, better coverage, or better light direction.

The goal is not only fewer watts.

The goal is better visibility where people actually work, walk, drive, pick, load, and inspect.

For warehouse projects, start with Luma Energy’s LED high bay lighting upgrade service.

You can also read the LED high bay lighting for warehouses buyer’s guide.

Commercial Mixed Use Building

Many commercial properties are not one simple lighting type.

A mixed use building may include:

• Offices

• Corridors

• Retail areas

• Storage rooms

• Washrooms

• Parking areas

• Exterior wall lights

• Mechanical rooms

• Sign lighting

• Common areas

That means the upgrade may need a mix of solutions.

Common Upgrade Mix

Area	Possible LED upgrade	What to check
Office areas	LED panels, troffers, or T8 tubes	Layout, comfort, controls
Corridors	LED panels, downlights, or retrofit kits	Runtime, occupancy, consistency
Retail areas	LED downlights, track lighting, accent lighting	Appearance, colour quality, brightness
Storage rooms	LED tubes or simple fixtures with sensors	Low use areas, wasted runtime
Exterior walls	LED wall packs	Safety, coverage, photocells
Parking areas	Area lights or wall packs	Mounting height, visibility, security
Mechanical rooms	LED strip fixtures or vapour tight fixtures	Durability and access

What Usually Affects Cost

A mixed building can be more complex because every area may need a different solution.

The main cost drivers are:

• Different fixture types

• Different ceiling conditions

• Different operating hours

• Multiple access requirements

• Tenant scheduling

• Exterior mounting heights

• Control zones

• Rebate eligibility by product type

Practical Tip

Group fixtures by area before pricing.

For example:

• Office fixtures

• Common area fixtures

• Exterior fixtures

• High ceiling fixtures

• Decorative fixtures

• Controls

This makes the estimate clearer and helps separate energy saving upgrades from appearance driven upgrades.

For mixed commercial buildings, start with Luma Energy’s commercial lighting upgrade service.

How Luma Energy Estimates Your Project

A good commercial LED lighting estimate should show more than a total price.

It should help you understand:

• What you have now

• What should replace it

• What the upgrade may save

• What rebates may apply

• How difficult installation will be

• Whether the project is worth doing

Luma Energy reviews the building before recommending a lighting upgrade.

Step 1: Review the Existing Lighting

The first step is to document the current lighting system.

This may include:

Item reviewed	Why it matters
Fixture count	Determines the scale of the project
Existing wattage	Helps calculate current energy use
Fixture type	Shows whether LED tubes, retrofit kits, or new fixtures make sense
Ballast condition	Important for fluorescent retrofit decisions
Lamp type	Helps compare old lighting against LED options
Ceiling height	Affects access, labour, and fixture selection
Mounting type	Determines how fixtures can be replaced or retrofitted
Light levels	Helps avoid underlighting or overlighting the space
Fixture condition	Damaged or outdated housings may point toward full replacement

Step 2: Understand How the Building Is Used

Lighting should match the way the building operates.

An office, warehouse, retail store, and industrial facility all use light differently.

Luma looks at:

• Operating hours

• Occupied and unoccupied areas

• Shift schedules

• Tenant schedules

• High traffic areas

• Low use rooms

• Safety sensitive areas

• Customer facing spaces

• Exterior lighting needs

This matters because the best lighting design is not always the same across the whole building.

For example, a warehouse aisle, private office, loading dock, and exterior wall light may each need a different approach.

Step 3: Choose the Right LED Upgrade Option

After reviewing the existing system, Luma compares practical upgrade options.

These may include:

• LED tube replacement

• LED retrofit kits

• New LED flat panels

• New LED troffers

• LED high bays

• LED potlights or downlights

• LED wall packs

• Exterior area lights

• Occupancy sensors

• Daylight controls

• Networked lighting controls

Simple Selection Guide

Existing condition	Possible recommendation
Fixtures are in good condition and layout works	LED tubes or retrofit kits may be reviewed
Fixtures are old, damaged, yellowed, or outdated	New LED fixtures may be better
High ceilings with old HID fixtures	LED high bays should be reviewed
Exterior lights run overnight	LED wall packs or area lights with controls may be reviewed
Rooms are often empty but lights stay on	Occupancy or vacancy sensors may help
Customer facing areas look dated	New fixtures may improve both appearance and efficiency

Step 4: Check the Rebate Path

Rebates can affect the final cost.

Before selecting products, Luma checks whether the project may fit:

• Save on Energy Instant Discounts

• Save on Energy Retrofit Program

• Other applicable incentive paths, where available

For many standard lighting products, the rebate path may involve Instant Discounts through participating distributors.

For some projects, such as networked lighting controls or specialized lighting, the Retrofit Program may need to be reviewed.

Use the lighting rebate estimator to get an early estimate of possible rebate potential.

Step 5: Estimate Savings and Payback

A lighting upgrade should be evaluated as a business decision.

Luma reviews:

Input	Why it matters
Current wattage	Helps estimate current electricity use
New LED wattage	Shows the expected reduction in energy use
Operating hours	One of the biggest savings drivers
Hydro cost	Affects the value of energy savings
Maintenance savings	Includes reduced lamp, ballast, and service work
Rebate amount	Reduces upfront project cost when eligible
Installation cost	Determines the investment required
Controls	May reduce runtime and improve savings in the right areas

This gives the business a clearer picture of cost, savings, rebate potential, and payback period.

You can also use Luma Energy’s lighting operating cost calculator and lighting retrofit savings calculator before requesting a quote.

Using Better Audit Data

For larger lighting projects, accurate estimates depend on clean fixture data, not rough notes. Luma Energy uses structured audit workflows to review fixture counts, wattages, operating hours, savings, rebates, and payback. Contractors who need a better way to organize this process can explore LumaQuote, a lighting audit and quoting software built for LED retrofit projects.

Step 6: Plan the Installation

Installation planning is especially important for active commercial buildings.

Luma reviews:

• Access requirements

• Lift requirements

• Work hours

• Tenant disruption

• Production schedules

• Safety requirements

• Phased installation

• Disposal of old lamps and fixtures

• Exterior access

• Parking or loading restrictions

The goal is to complete the lighting upgrade with as little disruption as possible.

For offices, that may mean working around staff or tenants.

For warehouses and industrial buildings, that may mean working around equipment, shipping areas, production schedules, or safety zones.
