Diana Lighting and Controls is a Canadian LED lighting manufacturer that works directly with electrical contractors across Canada. We design, manufacture, and deliver custom LED fixtures pre-wired and ready for installation, so your crew installs lighting instead of assembling it on site.
Custom LED Lighting Solutions for Electrical Contractors
Every project has specific requirements. Diana Lighting does not sell from stock. We manufacture to the exact specifications of the project, whether it is a custom residential build, a commercial renovation, or a retrofit of an existing installation. Share your drawings or describe what you need, and we manufacture and deliver directly to your job site.
Understanding Your Lighting Needs
From new construction to retrofit upgrades, Diana Lighting works with electrical contractors to identify the right fixture for the application. We assess ceiling height, lumen requirements, colour temperature, dimming compatibility, and controls integration before manufacturing begins. What arrives on site is a finished fixture that fits the space and connects cleanly, with no on-site troubleshooting required.
Custom LED Lighting Fixtures for Every Project
Diana Lighting manufactures custom LED fixtures across a range of residential and commercial applications including linear LED systems, cove lighting, under-cabinet and closet lighting, and stair lighting. Every fixture Diana Lighting produces is sized, profiled, and specified for the actual conditions of the space it is going into. No stock substitutions. No close alternatives. The fixture arrives ready to install in the conditions it was designed for.

Technical Support and Reliability
Eliminating Compatibility Issues
One of the most common problems electrical contractors face with LED lighting is compatibility between the LED driver, the dimmer, and the control system. These issues do not show up until the fixture is installed and the lighting system is live. Diana Lighting eliminates this problem at the source. Every fixture we manufacture is fully tested before it leaves our Canadian facility. Drivers and controls are verified for compatibility during the specification process, not discovered during installation. The fixture arrives pre-wired and ready to connect.
Some electrical contractors still source components separately and assemble on site, consuming time and labour that drives up project costs. More and more contractors have chosen to leave the manufacturing to Diana Lighting, gaining access to a more robust build, better warranties, and a straightforward installation experience. There are no compatibility issues between drivers, lighting controls, and LEDs because we resolve them before the fixture ships.
Heat Sink Design and Thermal Management
LED fixtures generate significantly less heat than incandescent or fluorescent sources, but they still require a properly designed heat sink to perform at their rated lifespan. When the heat sink is undersized or absent, the thermal load has nowhere to go and fixture lifespan drops well below rated hours. This becomes especially critical in enclosed applications such as ceiling recesses, linear modules, and under-cabinet installations. Diana Lighting designs every fixture with thermal management built in, using aluminum channels and heat sink configurations specified for the operating conditions of the application. Thermal management is where LED fixture quality is won or lost. Diana Lighting does not compromise on it.
Expert Guidance During Installation
Diana Lighting provides direct technical support to electrical contractors throughout the installation process. If a question arises on site about connections, driver placement, dimming integration, or controls compatibility, the contractor speaks directly with the people who manufactured the fixture. Not a distributor. Not a call centre. The manufacturer.
Efficiency and Performance
Energy Savings with LED Technology
LED lighting fixtures consume approximately 8 to 10 times less energy than incandescent sources for equivalent lumen output. LED technology converts the vast majority of its energy draw into usable light output, with minimal thermal waste. At current manufacturing standards, LED fixtures achieve output levels of approximately 130 lumens per watt, and progress in this area continues. For clients converting from fluorescent lamps or incandescent sources, the energy conservation impact is measurable on every hydro bill.
A properly specified LED fixture outlasts fluorescent tubes and incandescent bulbs by a substantial margin. A properly designed LED fixture with an adequate heat sink can achieve an average lifespan of 30,000 hours, which is up to 40 times longer than incandescent bulbs and four times longer than fluorescent tubes. For the electrical contractor, longer fixture life means fewer site returns, lower warranty exposure, and a better outcome for the client.
High Bay and Downlighting Options
Smart Lighting Integration
LED technology enabled a generation of lighting controls and automation that was not practical with traditional sources. Motion sensors, dimmers, and timers integrate more seamlessly with LED fixtures than with incandescent or fluorescent systems. More advanced applications include daylight harvesting, occupancy-based dimming, and circadian rhythm lighting, where the correlated colour temperature adjusts throughout the day. This last application has demonstrated measurable benefits in healthcare environments, retirement facilities, and other spaces occupied by people whose wellbeing is affected by light quality and colour.
LEDs are also capable of RGB colour output, allowing full-spectrum colour control through dedicated controllers. For clients who want dynamic or mood-responsive lighting in residential or hospitality settings, this capability opens applications that traditional lighting sources cannot match.
Why Electrical Contractors Choose Diana Lighting
Pre-Wired Delivery for Faster Installations
Diana Lighting delivers every fixture pre-wired and fully tested. The electrical contractor connects the fixture to the circuit. There is no on-site assembly, no component sourcing, and no troubleshooting of compatibility issues that should have been resolved before the fixture was built. This reduces labour time on site and eliminates the cost of mistakes that happen when assembly is rushed in the field.
IES-Certified Expertise Behind Every Project
Lawrence and Alex, the founders of Diana Lighting, hold IES certification from the Illuminating Engineering Society, the authoritative body for lighting practice in North America. Every project is handled directly by the people who hold that certification. When an electrical contractor specifies a Diana Lighting fixture, they are working with a manufacturer whose expertise is verified, not assumed.
Durability and Competitive Warranties
Diana Lighting manufactures every fixture from fine, durable materials using production processes developed specifically for custom LED manufacturing. Every product is backed by competitive warranties covering manufacturing defects and performance. Electrical contractors who specify Diana Lighting fixtures are not absorbing the risk of a poorly built product from an overseas supplier with no Canadian support.
Supporting Electrical Contractors Across Canada
Retrofit Projects
Retrofitting LED lighting into existing installations presents specific challenges. Existing electrical ballasts are not be compatible with LED lighting and require replacement. Ceiling depths constrain fixture dimensions. Phased installations require consistent product availability across multiple delivery windows. Diana Lighting designs retrofit-ready LED systems that work within the existing conditions of the installation. We assess the existing infrastructure during consultation and advise on what can be retained and what needs to be replaced, including electrical ballast compatibility and driver selection.

Long-Term Manufacturing Partnership
Electrical contractors who work with Diana Lighting once tend to come back. Not because of a loyalty program or pricing incentives, but because having a manufacturer who eliminates compatibility problems, delivers pre-wired products on schedule, and provides direct technical support during installation is genuinely difficult to find. We are not a supplier you place an order with and hope for the best. We are a manufacturing partner you build a working relationship with, and that relationship improves with every project.
FAQs for Electrical Contractors
Are your fixtures commercial grade and code compliant?
Yes. Diana Lighting manufactures fixtures to commercial-grade performance standards using fine, durable materials and production processes developed specifically for custom LED manufacturing. Lawrence and Alex hold IES certification, and every project is specified to meet the performance and safety requirements of the application. Documentation to support code compliance review is available on request.
Can you supply products only without installation?
Yes. Diana Lighting is a manufacturer, not an electrical contractor. We design, manufacture, and deliver custom LED fixtures directly to the job site, pre-wired and ready for installation by the electrical contractor. Installation is the contractor's scope. Our scope ends when the fixture arrives on site ready to connect.
Do you work with both electrical contractors and general contractors?
Yes. Diana Lighting's direct client base spans electrical contractors, general contractors, builders, architects, and interior designers across Canada. On projects where multiple trades are involved, we coordinate directly with each party to ensure the lighting integrates correctly with the millwork, electrical infrastructure, and construction schedule.
How does an LED retrofit project work with Diana Lighting?
A retrofit project begins with a consultation where we assess the existing installation, including the electrical infrastructure, ceiling conditions, and current fixture types. We identify which components can be retained, which need to be replaced, including electrical ballast compatibility, and what dimensional constraints affect fixture selection. We then manufacture retrofit-ready LED fixtures to the specific conditions of the existing installation and deliver pre-wired to the job site.
What is the result of automating lighting for a client?
A well-specified lighting control system reduces energy consumption by matching light output to actual occupancy and natural light levels. Occupancy sensors eliminate lighting in unoccupied zones. Daylight harvesting adjusts output based on available natural light. Scheduled dimming reduces output during off-peak hours. For the electrical contractor, delivering a project with integrated controls adds value to the scope and differentiates the installation from a standard switch-and-fixture job.
What are the key benefits of LED lighting for commercial electrical projects?
Commercial LED lighting reduces energy consumption by 5 to 8 times compared to incandescent sources for equivalent lumen output. At 30,000 hours or more of rated lifespan, LED fixtures significantly reduce the frequency of replacements and the maintenance burden on the building owner. Colour temperature ranges from 1,000K to 7,000K cover every commercial application from warm hospitality lighting to cool clinical environments. Integration with lighting controls and automation systems is more reliable with LED sources than with fluorescent lamps or incandescent bulbs.
How can electrical contractors transition effectively to LED lighting?
The transition to LED requires familiarity with driver technology, dimming compatibility, heat sink design, and colour temperature specification. The most effective approach is to build a relationship with a custom LED lighting manufacturer who has already worked through these challenges across a range of applications. Diana Lighting works with electrical contractors at every stage of the transition, from initial product education through to specification support and on-site installation guidance.
Why should electrical contractors specify LED lighting for their clients?
LED lighting delivers lower energy bills, longer fixture life, better light quality, and greater design flexibility than any traditional source. For clients converting from fluorescent lamps or incandescent bulbs, the return on the upgrade investment is measurable over a short period. For electrical contractors, specifying LED lighting from a manufacturer that eliminates compatibility problems and delivers pre-wired product reduces installation time and eliminates the callbacks that come from poorly assembled on-site solutions.
