Diana Lighting and Controls is a Canadian LED lighting manufacturer that works directly with interior designers at the specification stage. We do not sell off the shelf. Every fixture we produce is custom-designed and manufactured to the exact requirements of the project. If you are specifying lighting for a client who expects the result to match the vision, we are the manufacturer you want behind you.
How Diana Lighting Collaborates with Interior Designers
Most lighting manufacturers expect designers to browse a catalog, select a SKU, and place an order. Diana Lighting works differently. We engage at the specification stage, before anything is ordered or installed, and stay involved through to completion. The result is a lighting system that was designed for the project, not selected for it.
Understanding the Designer's Vision
Diana Lighting starts every project the same way: a direct conversation with the designer before anything is specified or ordered. We review your drawings, understand the architectural conditions of the space, the finish palette, the dimming requirements, and the ambiance you are designing toward. We ask the right questions early so that nothing needs to be corrected later.
Custom Solutions for Unique Projects
Diana Lighting manufactures custom LED lighting across the following categories:
- Linear LED lighting — any shape, length, and angle, recessed or surface-mounted, designed to the exact dimensions of the space
- Under-cabinet and closet LED lighting — touchless dimmable, available in standard or custom lengths, designed to integrate cleanly with millwork
- Stair LED lighting — uniform light distribution, multiple trim options, fully integrated into the stair structure
- Cove LED lighting — modular plug-and-play design, specified for the colour temperature and output of each individual space
Nothing in this list is pulled from a shelf. Every fixture is built to the exact requirements of your project, from first specification to final installation.
Technical Support During Specification
Specifying custom lighting in a complex architectural project involves technical decisions that affect the outcome. Dimmer compatibility, driver selection, correlated colour temperature, lighting calculations and millwork integration all need to be resolved before installation. Diana Lighting provides direct technical support throughout the specification process. You deal with the people who will manufacture the fixture, not a distributor reading from a spec sheet.
Types of Projects and Applications
Residential Lighting Solutions
Interior designers working on custom homes, luxury renovations, and high-end residential projects need a manufacturer who understands that lighting is an architectural element, not an afterthought. Diana Lighting specifies and manufactures residential LED fixtures for bedrooms, kitchens, living spaces, staircases, and millwork integration. Every fixture is designed around the specific dimensions, ceiling height, and mood lighting requirements of the room. and colour temperature are specified to complement the finish palette and daylight conditions of each space.
Commercial Lighting Applications
Commercial interiors require lighting that performs functionally while supporting the aesthetic intent of the design. Diana Lighting manufactures custom linear LED systems for offices, retail environments, hospitality spaces, and boutique commercial interiors. Our fixtures are specified for the architectural conditions of the space, including ceiling height, glare control requirements, and dimming integration. For interior designers working on commercial projects, we provide the same custom manufacturing and technical support we deliver on residential work.
Specialized Lighting for Unique Spaces
Some projects do not fit a standard category. Art galleries require precise accent lighting with high CRI . Staircases where the lighting must integrate flush with the structure and deliver uniform distribution with zero discomfort glare. Hospitality venues where mood lighting and atmosphere are as important as lumen output. Diana Lighting has the custom fabrication capabilities to design and manufacture fixtures for spaces that standard product lines cannot serve.
Importance of Custom LED Lighting Manufacturing in Design
Aligning with Design Intent
Off-the-shelf fixtures are designed to fit as many spaces as possible, which means they fit none of them precisely. For an interior designer working on a project where every dimension, finish, and material has been deliberately chosen, a fixture that is close enough is not good enough. Diana Lighting manufactures to the exact requirements of the design. Length, angle, profile, and finish are determined by the project, not by what is available in a standard product run. The result is a light fixture that belongs in the space rather than one that was installed in it.
Ensuring Colour Temperature Consistency
Colour temperature inconsistency is one of the most common ways a well-designed lighting scheme fails on site. Two fixtures from different production runs, or from different suppliers, can read differently under the same ceiling and undermine the entire composition. Diana Lighting controls colour temperature across every fixture in a project from a single Canadian manufacturing facility. When you specify 3000K across a residential interior, every linear run, every cove, and every under-cabinet system ships at 3000K. What you specified is what gets installed.
Accommodating Custom Dimensions and Finishes
Standard product dimensions rarely align with the conditions of a custom interior design project. Millwork openings, ceiling recesses, stair profiles, and architectural details are all specific to the space. Diana Lighting's linear LED systems are manufactured to any length, shape, and angle the design requires. Under-cabinet and closet lighting is available in standard lengths or custom-manufactured to fit the exact millwork specifications. Standard sizes do not apply here. Every fixture is built to the dimensions the project demands.
Custom LED Lighting Products Diana Lightning and Control Can Specify
Diana Lighting manufactures custom LED fixtures across the following categories. Every product is available through consultation and is manufactured to the specifications of the project.
Task Lighting and Ambient Solutions
Diana Lighting's core product range covers the task and ambient lighting needs of most residential and commercial interior design projects. Custom linear LED systems provide precise, high-output illumination for kitchens, desks, workspaces, and architectural details. Under-cabinet and closet LED lighting delivers focused task lighting that integrates cleanly with millwork, available in standard or custom lengths with touchless dimming. Cove LED lighting adds a layer of ambient illumination to living spaces, corridors, and commercial interiors, specified for colour temperature and output to suit the mood lighting intent of each room.
Accent Lighting
Diana Lighting's linear and cove systems can be specified for accent lighting applications, drawing attention to architectural features, wall finishes, ceiling planes, and design details. Recessed linear profiles and stair lighting systems in particular are well suited to accent applications where the fixture itself should disappear and the effect should lead.
How Diana Lighting Fits Into Your Design Workflow
Early Engagement
Getting Diana Lighting involved at the drawing stage produces measurably better results than bringing us in after decisions have already been made. Lighting decisions that are left to the end of a design process create problems that are expensive to fix. Fixture dimensions that do not fit the millwork. Colour temperatures that clash with the finish palette. Dimming systems that are incompatible with the specified controls. We engage at the drawing stage, review the architectural conditions, flag potential issues, and provide technical input before anything is locked in. This protects the designer, the client, and the project.
Creating Tailored Lighting Plans
Diana Lighting does not hand interior designers a product list and step back. We develop a lighting plan specific to the project, covering ambient lighting, task lighting, and accent lighting requirements room by room. Colour temperature, lumen output, dimming compatibility, and fixture placement are all addressed before specification is finalised. The plan reflects the design intent, the architectural conditions of the space, and the practical requirements of installation. When the fixtures arrive on site, they fit, they perform, and they look exactly as specified.
FAQs
What are the four main types of lighting in interior design?
Lighting design in residential and commercial interiors works across four functional categories. The first is ambient lighting, which establishes the base level of illumination throughout the space. Task lighting targets specific work areas such as kitchen countertops, desks, and reading surfaces. Accent lighting draws attention to architectural features, wall finishes, or design details. Decorative lighting makes the fixture itself part of the design, contributing to the visual character of the space as much as the light it produces. A well-designed interior uses all four intentionally and in proportion to each other. Diana Lighting manufactures custom LED fixtures that serve ambient, task, and accent applications across all project types.
What is architectural lighting in interior design?
Architectural lighting refers to fixtures that are integrated into the structure of a space rather than applied to it. Recessed linear profiles, cove lighting, stair lighting, and under-cabinet systems are all architectural lighting applications. The fixture is designed to disappear into the architecture while the effect it produces defines the space. Diana Lighting specialises in architectural LED lighting, manufacturing fixtures that are built into the exact dimensions of the ceiling, wall, staircase, or millwork detail they serve.
What is ambient lighting in interior design?
Ambient lighting forms the base of any layered lighting scheme, establishing the overall brightness and tone of the space before task and accent layers are added. It provides the general brightness that allows the room to function and sets the tone for every other lighting layer above it. Cove lighting, recessed linear systems, and ceiling-integrated LED fixtures are common ambient lighting solutions in contemporary interior design. Colour temperature and lumen output for ambient lighting should be specified relative to the natural daylight conditions of the space and the mood the designer is creating.
What quality of light do I need for my interior design project?
Light quality in a professional interior design context is determined by three primary factors: colour temperature, colour rendering index, and glare control. Colour temperature affects how warm or cool the space feels and how finishes and materials read under artificial light. Colour rendering index determines how accurately colours are reproduced, which is critical in spaces where material selection and finish palette are central to the design. Glare control affects comfort and the perception of brightness. Diana Lighting specifies all three for every project during the consultation process.
What impact does daylight have in interior design?
Daylight is the reference point against which all artificial lighting is measured. How much natural light enters a space, from which direction, and at what quality, shapes every artificial lighting decision that follows. Spaces with strong daylight exposure require artificial lighting that can dim responsively without creating colour temperature shifts. Diana Lighting specifies dimming-compatible LED systems that work with the natural light conditions of each space rather than against them.
How do you get the right mix of decorative and architectural lighting in an interior design project?
Architectural lighting establishes the performance of the space. Decorative lighting establishes its character. The right mix depends on the function of the room, the ceiling height, the finish palette, and the atmosphere the designer is creating. In most high-end residential and commercial projects, architectural lighting carries the functional load while decorative fixtures serve as focal points. Diana Lighting focuses on the architectural layer, manufacturing custom linear, cove, stair, and under-cabinet systems that perform precisely so that the decorative layer can do its job without compromise.
Where do interior designers source custom LED lighting in Canada?
Most lighting available through retail and wholesale channels is mass-produced to standard dimensions and specifications. For projects where standard dimensions and off-the-shelf colour temperatures are not acceptable, interior designers across Canada work with Diana Lighting and Controls. We manufacture custom LED fixtures to the exact specifications of the project, engage at the drawing stage, and provide direct technical support through to installation.
Why is lighting design important in interior design?
Lighting determines how every other element of an interior design is perceived. The colour of a wall, the texture of a material, the proportion of a room; all of these are experienced through light. A space that is beautifully designed and poorly lit will read as poorly designed. Lighting is not the finishing touch on an interior design project. It is a fundamental design decision that should be made at the same time as every other architectural and material choice.
Working with an Interior Designer on Your Project?
If you are a homeowner, developer, or contractor working with an interior designer, ask them about Diana Lighting. Better yet, send them this page. Getting Diana Lighting into the conversation early produces better outcomes for the designer, the client, and the project.
Ready to Specify with a Manufacturer Who Gets It?
Designers who work with Diana Lighting stop chasing suppliers and start collaborating with a manufacturer who understands what specification-grade means. We engage early, manufacture to your exact requirements, and stay involved through to installation.
