Luma Energy works with Ontario businesses that want better lighting performance, lower operating costs, and smarter control over how their buildings use electricity. In 2026, lighting upgrades are no longer just about swapping old fixtures for LED. More owners and facility managers now want systems that respond to occupancy, daylight, schedules, and real building use. That shift makes lighting controls one of the most important parts of a modern retrofit strategy.
For offices, warehouses, retail stores, schools, and multi use commercial properties, the right controls can reduce wasted energy, improve user comfort, and make the entire lighting system feel more intentional. Controls also help buildings adapt to different work patterns, including hybrid office use, variable warehouse traffic, after hours cleaning, and seasonal daylight changes. According to the U.S. Department of Energy, lighting controls save energy by automatically turning lights off when they are not needed or reducing light levels when full brightness is unnecessary. Common control types include dimmers, timers, motion sensors, occupancy sensors, and photosensors.
This guide explains what lighting controls actually do, where they make the biggest difference, what types of systems make sense for different building types, and how to decide whether they belong in your next project. If you are planning a broader upgrade, this article pairs well with our guides on commercial lighting upgrades, industrial lighting upgrades, and office lighting upgrades.
Why lighting controls matter more in 2026
A few years ago, many commercial lighting projects focused mostly on fixture efficiency. That still matters, but buyers now expect more. Lighting industry reporting in Canada shows that decision makers increasingly prioritize measurable value, digital integration, automation, scalability, and long term operational savings when choosing lighting systems. Smart and connected lighting is moving from a premium feature to a standard expectation across commercial, industrial, logistics, and institutional projects.
That shift makes sense in the field. A basic LED upgrade lowers wattage. A controlled LED system lowers wattage and reduces unnecessary run time. In real buildings, that second part is where a lot of hidden waste lives. Lights stay on in empty boardrooms. Back rooms remain fully lit all night. Warehouse aisles are bright even when nobody is there. Perimeter zones fight against daylight from windows. Controls fix those problems without requiring staff to constantly manage switches.
ENERGY STAR notes that occupancy sensors can save roughly 15 to 30 percent on lighting costs in the right spaces, especially low traffic areas such as storage rooms, meeting rooms, and back of house spaces. The U.S. Department of Energy also notes that LEDs are especially well suited to on off operation with occupancy and daylight sensors because switching does not negatively affect LED lifetime the way it can with fluorescent lamps.
For building owners, that means the question is no longer “Should we use controls at all?” It is “Where do controls make the most sense, and how advanced should the system be?”
What lighting controls actually do
Lighting controls are devices or systems that adjust lighting output based on time, occupancy, daylight, or user preference. Some are simple and local. Others are networked across an entire building.
The most common control types
Occupancy sensors
These detect movement and turn lights on when someone enters a space and off after the room is vacant. They work well in washrooms, storage rooms, private offices, utility rooms, copy rooms, and some warehouse zones. ENERGY STAR specifically highlights these as a practical energy saving measure for commercial buildings.
Vacancy sensors
These require a person to turn the lights on manually, but switch them off automatically when the room is empty. In some spaces, they save more energy than occupancy sensors because they avoid turning lights on unnecessarily.
Photosensors and daylight harvesting
These detect available daylight and dim or switch electric lighting accordingly. They make the most sense near windows, skylights, curtain walls, and glazed entrances. The DOE lists photosensors among the main lighting control options because they reduce light levels when natural light is available.
Time scheduling
This approach turns lights on and off according to a programmed schedule. It works well in offices, exterior lighting, schools, and buildings with predictable operating hours.
Dimming controls
These reduce light output rather than switching fixtures fully on or off. Dimming improves comfort, reduces glare, and can extend useful system life when used properly.
Networked lighting controls
These connect fixtures, sensors, and switches into one coordinated system. Building operators can program scenes, monitor performance, group zones, and adjust settings from software rather than handling each space manually. DOE guidance on building controls describes these systems as part of a broader energy management and operational strategy for buildings.
Where lighting controls make the biggest impact
The best control strategy depends on the building, not just the fixture. A warehouse, office, and retail store should not all be treated the same.
Offices
Office buildings are one of the strongest use cases for controls because occupancy is inconsistent. Hybrid work has made that even more obvious. Conference rooms, private offices, break rooms, and training rooms often sit empty for long periods.
For office projects, good control design usually includes:
occupancy or vacancy sensors in enclosed rooms
daylight harvesting near windows
scheduling for common areas
dimming in meeting spaces
zoning that separates perimeter lighting from interior lighting
Research from the National Research Council of Canada shows that lighting quality in workplaces is tied to visibility, comfort, and broader workplace outcomes. NRC work has also found that giving users personal control over lighting can improve environmental satisfaction and can reduce energy use by around 10 percent compared with a fixed system.
That matters because office lighting is not only an efficiency issue. It is also about how a workspace feels. A bright but poorly controlled office can still produce glare, visual fatigue, and an overlit environment. If you are reviewing a broader office upgrade, our article on 2x4 LED flat panel lights is a useful companion.
Warehouses and distribution centres
Warehouses often have some of the longest burn hours in a commercial portfolio. They also tend to have uneven occupancy. Some aisles are busy all day. Others are accessed occasionally. Shipping areas spike at specific times. Storage mezzanines may sit mostly unused.
That makes controls extremely valuable in:
aisle lighting
racking zones
loading docks
maintenance rooms
lunchrooms and washrooms
exterior service areas
A practical warehouse strategy often combines high bay fixtures with aisle based occupancy sensing and reduced background light levels during vacant periods. Networked systems are especially helpful in larger spaces because the site team can fine tune timing, sensitivity, grouping, and dim levels after installation.
If your facility has higher ceilings or open industrial floor plates, see our service page on high bay lighting upgrades and our article on LED high bay lighting for warehouses.
Retail stores and showrooms
Retail lighting has a different job. It must save energy, but it also has to support merchandising, brand presentation, and customer comfort. Full automation is not always the goal. The right goal is smarter control.
In retail, controls work best when they support:
daylight response near storefront glazing
separate switching for accent and ambient lighting
scheduling for opening and closing hours
scene control for displays or featured areas
back room and stock room occupancy sensing
The biggest mistake in retail is over-automating customer facing zones in a way that causes visible fluctuations or delayed response. Public areas should feel seamless. Back of house spaces are where more aggressive energy savings usually belong.
Exterior areas
Exterior lighting often runs longer than interior lighting, especially in winter. Controls matter here too. Time clocks, photocells, and motion based strategies can keep sites safe while avoiding unnecessary overnight energy use.
Good exterior control design helps with:
parking lots
wall packs
walkways
entrances
service yards
building perimeter lighting
ENERGY STAR guidance on outdoor lighting notes that outdoor fixtures often include daylight shutoff or motion sensing, and supporting controls can improve overall performance.

Simple controls versus networked systems
Not every building needs a fully networked smart lighting platform. Some projects get excellent results from straightforward controls. Others benefit from a more advanced system.
Here is a practical comparison:
Control approach | Best fit | Main benefit | Main limitation |
Standalone occupancy sensors | small rooms, washrooms, storage, private offices | low cost and easy savings | limited central visibility |
Time clocks and scheduling | predictable operating hours, exterior lighting | reliable automation | less responsive to real occupancy |
Daylight harvesting | perimeter offices, glazed retail, schools | cuts daytime waste | requires proper commissioning |
Local dimming | boardrooms, training rooms, showrooms | comfort and flexibility | user dependent |
Networked controls | large offices, warehouses, multi zone buildings | analytics, zoning, scalability | higher upfront complexity |
The right choice depends on building size, operating pattern, staff expectations, and whether the owner wants ongoing visibility into performance.
What owners often get wrong
Lighting controls are powerful, but they are not magic. A poor design or sloppy setup can make a good system feel annoying.
Common mistakes
Using sensors where they do not suit the space
A motion sensor in a quiet office or washroom with poor line of sight can create false offs. Placement matters.
Overcomplicating the system
Some buildings do not need advanced dashboards, apps, and custom scenes everywhere. Too much complexity can overwhelm staff and reduce long term adoption.
Ignoring commissioning
Even good controls can underperform if timeout settings, daylight thresholds, dim levels, and zoning are not adjusted after installation. ENERGY STAR specifically warns that good equipment can still be installed incorrectly.
Treating all spaces the same
Meeting rooms, corridors, open offices, racking aisles, and showrooms all behave differently. One blanket strategy usually underperforms.
Focusing only on wattage
A lower watt fixture is not enough if lights still run all day in empty spaces. Real savings come from fixture efficiency plus control logic.
A practical example
Imagine a 25,000 square foot mixed use commercial building in Ontario with the following spaces:
open office area
6 enclosed offices
3 meeting rooms
warehouse/storage section
shipping door
lunchroom
perimeter windows on two sides
A smart but practical control plan might look like this:
enclosed offices get vacancy sensors
meeting rooms get occupancy sensors plus dimming scenes
open office perimeter rows get daylight harvesting
warehouse aisles get motion based high bay dimming
lunchroom and washrooms get occupancy sensors
exterior doors and perimeter lights run on photocell plus schedule control
site manager gets basic central scheduling access
That is not futuristic. It is just good design. It cuts avoidable run time, improves user experience, and gives the building a more responsive lighting system.
How lighting controls fit into a full retrofit
Controls work best when planned as part of the full lighting design, not added at the end.
That means reviewing:
fixture layout
mounting heights
line of sight for sensors
expected occupancy patterns
window locations
zoning opportunities
emergency lighting requirements
future tenant or usage changes
This is one reason we usually recommend evaluating controls during a broader retrofit conversation. If you are replacing troffers, pot lights, wall packs, or high bays anyway, that is the right time to decide how those fixtures should behave.

What 2026 best practice looks like
In 2026, strong commercial lighting design is moving in a clear direction. Canadian lighting market coverage points to value based buying, integration capability, sustainability, and adaptability as key purchase drivers. That means good projects are no longer judged only by fixture cost. They are judged by how well the system performs over time.
For most Ontario commercial buildings, current best practice looks like this:
1- Use LED fixtures as the baseline
DOE notes LED is already the most energy efficient lighting technology, with some specialized products reaching 150 lumens per watt or more.
2- Add controls where they clearly match the space
Not every area needs networked intelligence, but most buildings have enough variable use to justify at least some controls.
3- Prioritize occupant comfort
Workplace research consistently shows that good lighting quality and a degree of user control matter for satisfaction and productivity.
4- Keep operation simple
The best control system is one the site team will actually use and understand.
5- Commission and fine tune
Settings should be adjusted after occupancy, not just left at factory defaults.
Final thoughts
A lot of commercial buildings in Ontario still waste electricity through lighting that runs harder and longer than necessary. Upgrading fixtures helps. Adding the right controls helps more.
Lighting controls are one of the clearest ways to make a retrofit more intelligent without making it gimmicky. They reduce wasted run time, improve space by space responsiveness, and support better building performance overall. In offices, they improve comfort and flexibility. In warehouses, they cut waste in low traffic zones. In retail, they help balance presentation with efficiency. In exterior areas, they improve safety without unnecessary overnight burn.

FAQ: Commercial Lighting Controls
What are lighting controls in commercial buildings?
Lighting controls are systems or devices that adjust how and when lights operate in a building. They can turn lights on or off, dim them, respond to occupancy, follow schedules, or reduce output when daylight is available. In commercial buildings, they help reduce wasted energy while improving comfort and overall lighting performance.
Do lighting controls really save energy in offices and warehouses?
Yes. Lighting controls can reduce unnecessary run time by making sure lights are only used when they are actually needed. In offices, this often means lights in meeting rooms, private offices, and break rooms do not stay on when the space is empty. In warehouses, controls help cut waste in aisles, storage zones, and loading areas that are not occupied all day.
What types of lighting controls are best for commercial buildings?
The best lighting controls depend on the building and how the space is used. Common options include occupancy sensors, vacancy sensors, daylight harvesting controls, dimmers, scheduling controls, and networked lighting systems. Offices often benefit from daylight and room based controls, while warehouses usually benefit from high bay motion sensing and zone based operation.
Are occupancy sensors worth it for commercial spaces?
Yes, in many cases they are. Occupancy sensors are especially useful in spaces with irregular use, such as washrooms, storage rooms, private offices, lunchrooms, copy rooms, and meeting rooms. They help reduce energy waste without requiring staff to remember to switch lights off manually.
What is the difference between occupancy sensors and vacancy sensors?
Occupancy sensors turn lights on automatically when someone enters a space and off when the room becomes empty. Vacancy sensors require someone to turn the lights on manually, but they switch them off automatically when the space is vacant. Vacancy sensors can sometimes save more energy in spaces where automatic on is not always needed.
Should lighting controls be installed during an LED retrofit?
Yes, that is usually the best time to add them. When a building is already upgrading to LED fixtures, it is much easier to plan controls around the new layout, fixture types, mounting heights, and building use. Adding controls during a retrofit also helps create a more complete lighting system instead of treating controls as an afterthought.
Are networked lighting controls better than standalone controls?
Not always. Networked lighting controls are better for larger or more complex buildings that need zoning, scheduling, data visibility, and future flexibility. Standalone controls can still work very well in smaller buildings or in simple applications where low cost and ease of use matter more than software level control. The right choice depends on the size of the building, occupancy patterns, and operational goals.
