Lighting Design and Photometrics

Lighting layouts and photometric design built around how each area of your building is used, so light levels and uniformity are right the first time. Part of every Think Green Solutions LED lighting retrofit.

Swapping fixtures one for one keeps the old layout, which was designed around a different light source, beam spread and often a different mounting height. It is one of the most common reasons an LED retrofit that is technically correct still looks patchy.

Every Think Green Solutions LED lighting retrofit includes lighting design and layout design, and where a project calls for it, we model the space in lighting software before anything is ordered. Each area gets a design built for how it is used, not a copy of the old grid.

At Rona Guelph, the store already had LED but was still too dark. A location-specific design treated the high-bay retail spaces, offices and lower-ceiling zones separately, and focused on light placement and distribution rather than simply replacing fixtures.

What Goes Into a Layout

A good lighting design starts with the building and the work done in it, then chooses the fixtures.

  • Mounting height

    Height sets the fixture family and beam distribution. By common industry convention, high bays are specified above roughly 6 m (20 ft) and low bays below it.

  • Racking, aisles and floor plan

    Fixtures are laid out to your racking, aisle widths and work areas, so light lands where people work.

  • Light levels by area

    Inspection, assembly and picking need more light than storage or corridors, so each area gets its own target.

  • Uniformity, shadows and glare

    Even light with shadows and glare kept to a minimum, which is what Ontario's workplace lighting regulation asks for.

  • Controls zones

    Where networked controls make sense, sensors and zones are planned into the layout from the start.

  • What to keep

    Where existing LED is working well, we tell you and design around it.

Modelled Before It Is Installed

Where a project calls for it, we model the space in lighting software before anything is ordered. The model uses each fixture's photometric data with your ceiling height, racking and aisle widths to predict how light will fall across the space. You receive the photometric layout, the predicted foot-candle levels and uniformity for each area, and the light layout and design your installation follows.

  • Light levels by zone

    Predicted light levels for each area, checked against the target for the work done there.

  • Even coverage

    Fixture spacing and distribution chosen so the light overlaps evenly instead of leaving dark patches.

  • The right fixture count

    The number and type of fixtures your building actually needs, not a copy of the old grid.

  • Right the first time

    Problems are found on the computer, before the order is placed and the lifts arrive.

Designed, Installedand Warrantied by One Team

The design is part of a turnkey project, so one team is accountable from the layout through installation and warranty.

  • Free facility assessment

    Our team spends one to four hours on site, then presents a proposal with the costs, savings and incentives.

  • 99% accurate second count

    Before install, our team returns to recheck every fixture, so the order matches your building.

  • Our own fixtures

    We design our own fixtures, have them manufactured and sell them direct, then administer the warranty ourselves.

  • Built to last

    Our longest-running projects are over 16 years old with a failure rate under 5%.

FAQs Lighting Design

Straight answers to the questions facility managers ask us about lighting design and photometric layouts.

A computer model of how light from each fixture will fall across a space before anything is installed. It combines the fixture's photometric data with the mounting height, room dimensions, racking and aisle widths to predict light levels and how evenly they are spread, so the fixture choice, count and spacing can be set before the order is placed.

When we model your space, you receive a photometric layout, the predicted foot-candle levels for each area, the uniformity of that light across the floor, and the light layout and design that sets the fixture type, count and placement. You see all of it before anything is ordered or installed.

The old layout was designed around a different light source, beam spread and often a different mounting height. Keeping the old grid is one of the most common reasons an LED retrofit looks patchy. At Rona Guelph, the store already had LED and was still too dark until a location-specific design fixed it.

It depends on the work done there: inspection, assembly and picking need more light than storage or corridors. Federally regulated workplaces must meet the minimum levels in the Canada Occupational Health and Safety Regulations. Ontario's regulation for provincially regulated workplaces sets no lux figure, but requires that shadows and glare be reduced to a minimum. The design sets a target area by area.

Mounting height decides it. By common industry convention, high bays are specified above roughly 6 m (20 ft) and low bays below it, although no code sets a minimum height. Beam distribution and spacing for your layout matter more than the label.

Yes. Where existing LED is working well, we tell you and design around it, and focus the upgrade on the areas where it pays back.

The facility assessment is free. Our team spends one to four hours on site reviewing your lighting and how each area is used, then presents a proposal with the costs, savings and incentives before you commit. We also offer full financing on projects.
