General contractors do not have time for lighting that arrives late, does not fit the rough-in, or requires three calls to a distributor to get a straight answer. Bad lighting coordination creates delays, callbacks, and cost overruns that fall on the contractor to explain. We ensure that does not happen.
How Diana Works with General Contractors
Understanding Contractor Needs
General contractors need lighting that fits the rough-in, arrives when the schedule requires it, and does not create problems for the electrical trade. Diana Lighting is built around that understanding. We do not operate like a distributor who takes an order and ships whatever is closest to what was requested. We manufacture to the exact dimensions and performance requirements of your project, and we stay available throughout the build to address anything that comes up on site.
Seamless Coordination with Trades
Lighting installation problems are almost always coordination problems. A ceiling recess that does not account for driver clearance. A millwork opening that is two centimetres short. An electrical contractor who received no dimensional drawings and is working from guesswork. Diana Lighting coordinates directly with the electrical contractor, the millwork fabricator, and any other trade involved in the lighting installation. We provide dimensional drawings, installation documentation, and direct technical support throughout the construction process so that problems are resolved before they become delays.
Engagement in Early Project Stages
The earlier Diana Lighting is involved in a project, the fewer surprises arise during construction. When we are brought in during planning, we can review the lighting layout against the architectural conditions, flag integration challenges before rough-in begins, and confirm that every fixture will fit and perform as specified. Contractors who engage us early finish the lighting scope faster, with fewer callbacks and no last-minute substitutions.
Types of Projects and Applications
Residential Construction Projects
General contractors building custom homes, luxury renovations, and high-end residential projects need lighting that integrates into the architecture without creating problems for the trades installing it. Diana Lighting manufactures residential LED fixtures for ceiling recesses, cove profiles, stair integration, under-cabinet applications, and millwork details. Every fixture is built to the exact dimensions of the space, coordinated with the millwork fabricator and electrical contractor, and delivered to fit the rough-in the first time.
Commercial Renovation Applications
Retrofitting lighting into existing commercial spaces presents specific challenges. Ceiling depths are constrained. Electrical infrastructure may not support modern LED drivers without ballast replacement. Phased installations require consistent product availability across multiple delivery windows. Diana Lighting designs retrofit-ready LED systems for commercial renovations, specifying fixtures that work within the existing conditions of the space rather than requiring structural modifications to accommodate them. We assess the existing installation during consultation and advise on what can be retained and what needs to be replaced.
Indoor and Outdoor Lighting Solutions
Diana Lighting manufactures custom LED solutions for interior applications across residential and commercial construction projects, including linear LED lighting systems, cove lighting, stair lighting, and under-cabinet installations.
Diana Lighting can provide outdoor lighting solutions for residential and commercial construction projects. We manufacture outdoor-rated linear LED lighting systems for applications such as railings, architectural features, pathways, and exterior gathering spaces. Where a project requires other outdoor fixture types, Diana Lighting can also assist with product specification and sourcing to ensure compatibility with the overall lighting design and project requirements.
Why Custom Manufacturing Matters for Contractor Projects
Tailored Solutions for Unique Specifications
Standard fixtures create standard problems. A linear run that is 10 centimetres too long. An under-cabinet strip that does not match the millwork opening. A stair profile that requires a trim option the manufacturer does not stock. Every fixture Diana Lighting builds is sized, profiled, and specified for the actual conditions of your project. Linear systems are available in any length, shape, and angle. Under-cabinet and closet lighting is manufactured in standard or custom lengths with touchless dimming built in. Standard sizes do not apply here. Every fixture is built to the dimensions the project requires, with nothing to substitute or explain after the fact.
Addressing Common Installation Challenges
Most lighting installation problems are not electrical problems. They are dimensional and coordination problems that show up on site because nobody resolved them before construction began. Diana Lighting's modular plug-and-play cove lighting system is designed specifically to reduce installation time and eliminate dark spots across ceiling runs. Fixtures arrive with dimensional drawings and installation documentation that the electrical contractor can work from directly. The goal is a lighting scope that the trades can execute without improvising.
Ensuring Consistent Product Quality
Every Diana Lighting fixture is manufactured from fine, durable materials using 3D printing capabilities developed for custom LED production. Colour temperature is controlled across every fixture in a project from a single Canadian manufacturing facility, which means the linear run in the living room and the cove system in the hallway ship at the same specified temperature. Product quality does not vary between production runs. What is specified is what arrives on site, consistently across the entire project and backed by competitive warranties.
Product Categories General Contractors Can Specify Through Diana Lighting
Diana Lighting manufactures custom LED fixtures across the following categories. Every product is available through consultation and built to the specifications of the project.
Indoor Lighting Products
Diana Lighting's confirmed product range for contractor projects covers the core LED lighting requirements of residential and commercial builds. Custom linear LED systems are manufactured in any length, shape, and angle for ceiling applications, architectural details, and cove profiles. Under-cabinet and closet LED lighting is available in standard or custom lengths with touchless dimming. Stair LED lighting delivers uniform light distribution across multiple trim options and integrates directly into the stair structure. Cove LED lighting uses a modular plug-and-play design that reduces installation time and eliminates dark spots across ceiling runs.
Outdoor Lighting Options
While Diana Lighting's primary focus is custom indoor lighting systems, we can also provide outdoor-rated linear LED lighting for applications such as railings, architectural features, and exterior spaces. Where a project requires additional outdoor fixture types, we can assist with product specification and sourcing as part of a complete lighting solution.
Complete Installation-Ready Systems
Diana Lighting supplies complete lighting systems that include the components required for installation, including mounting hardware and other project-specific accessories. General contractors and trades receive a complete, coordinated solution rather than a collection of individual parts that must be sourced separately. This simplifies installation, reduces compatibility issues, and helps keep the lighting scope on schedule.
Consultation and Coordination Process
Initial Consultation and Design Collaboration
Every Diana Lighting project begins with a direct conversation. For general contractors, that means reviewing the project scope, the lighting layout, the rough-in conditions, and the construction schedule before anything is specified or ordered. We identify dimensional requirements, coordinate with the design team or architect if one is involved, and confirm that every fixture will fit the space and work with the electrical infrastructure already planned. No assumptions. No surprises during installation.
Technical Support During Installation
Diana Lighting stays involved after the order is placed. Our team is available to support the electrical contractor directly during installation, answering technical questions about connections, dimming integration, driver placement, and fixture positioning. We provide dimensional drawings and installation documentation with every project so the trades have what they need to execute without guesswork. If something comes up on site, you deal with the people who manufactured the fixture, not a distributor reading from a product sheet.
On-Schedule Delivery and Post-Installation Support
Diana Lighting manufactures in Canada, which means shorter lead times and direct communication on delivery status. We build to the construction schedule, not to our own production convenience. Every fixture ships with the documentation needed for installation and is backed by industry-standard warranties covering manufacturing defects and performance.
FAQs for General Contractors
How does working with a custom LED lighting manufacturer differ from a lighting supply distributor?
A lighting supply distributor carries stock and ships what is available. If the stock does not match the specification, the contractor gets the closest alternative and works around it. Diana Lighting manufactures to the specification of the project. If the ceiling recess requires a 2,200mm linear fixture at 3000K with a recessed profile, that is what gets built. There are no close alternatives and no workarounds. The fixture arrives ready to install in the conditions it was designed for.
What are the lighting requirements for construction projects in Canada?
Commercial and residential construction projects in Canada must meet lighting requirements set out by the National Building Code, provincial building codes, and in some cases energy efficiency standards such as those referenced by ASHRAE 90.1. Requirements cover minimum illuminance levels by space type, emergency lighting provisions, and in commercial applications, lighting power density limits. Diana Lighting specifies fixtures that meet the performance requirements of the space and can provide documentation to support code compliance review where required.
Can a general contractor coordinate lighting directly with Diana Lighting without an architect or designer?
Yes. Diana Lighting works directly with general contractors on projects where no architect or interior designer is involved. We assess the space, review the construction documents, and develop a lighting specification based on the functional and aesthetic requirements of the project. The contractor deals directly with our team from first consultation through to delivery and installation support.
Where do general contractors typically source custom LED lighting in Canada?
Most contractors source lighting through distributors or big box retailers, which limits them to standard stock sizes, generic colour temperatures, and no technical support during installation. For projects that require custom dimensions, specific colour temperature consistency, or integration with millwork and architectural details, contractors across Canada work with Diana Lighting and Controls. We manufacture custom LED fixtures in Canada, coordinate directly with trades, and deliver to the construction schedule.
How does Diana Lighting support electrical contractors during installation?
Diana Lighting provides dimensional drawings, installation documentation, and direct technical support to the electrical contractor throughout the installation process. Our team answers directly on connections, dimming setup, driver placement, and fixture positioning throughout the installation. If a problem arises on site, the electrical contractor speaks directly with the people who manufactured the fixture, not a distributor or a call centre.
