Architectural Lighting Design Guide
Professional architectural lighting requires more than brightness alone. Visual comfort, beam control, color accuracy, optical design, and proper application all contribute to the overall lighting experience. The following guide helps designers, contractors, and project managers select the most suitable commercial downlight solution.
Reflector Selection Guide
| Reflector Type | Lighting Characteristic | Best For |
|---|---|---|
| Angled Reflector | Provides directional beam control and strong visual focus. | Retail displays, artwork, merchandise highlighting, feature walls. |
| Curved Reflector | Balanced beam distribution with smooth light transitions. | Offices, hotels, restaurants, reception areas, and general architectural lighting. |
| Black Reflector | Maximum glare control and enhanced visual comfort. | Luxury retail, galleries, museums, executive spaces, and premium interiors. |
Color Quality High CRI Lighting Guide Compare color rendering levels and recommended applications
Color Rendering Index (CRI) measures how accurately a light source reveals the true colors of objects compared to natural daylight. High-CRI lighting is critical in commercial and architectural environments where color accuracy directly affects product presentation, material appearance, and customer experience.
| CRI Level | Color Performance | Typical Applications |
|---|---|---|
| CRI 80+ | Standard color rendering | Basic commercial lighting |
| CRI 90+ | Enhanced color accuracy | Retail stores, hospitality environments |
| CRI 95–97+ | Exceptional color fidelity and natural appearance | Architectural projects, luxury interiors, galleries, showrooms, museums |
The CDG Series architectural downlights deliver CRI>97 in US versions and CRI>95 in EU versions, ensuring outstanding color reproduction for demanding commercial applications.

Changed the dining room downlights and the glare difference was more noticeable than I expected
We renovated the dining area last year and the old ceiling spots were one of the things I really wanted to change.
They were bright enough, but you could see the light source from almost anywhere in the room, especially when sitting at the tables.
We ended up using the deeper curved-reflector downlights instead. The room still has plenty of light, but the ceiling feels much calmer now and the fixtures don’t grab your attention as much.
I also like the way the light transitions across the tables instead of looking like a series of harsh spots.
The installation took a little longer because we spent quite a bit of time getting the spacing right, but I’m glad we did.

Thanks for sharing the finished project.
The Curved Reflector CDG models are designed for smoother beam transitions and balanced architectural illumination, which is why they work well in restaurants, hotels, reception areas and similar spaces where visual comfort matters.
All CDG models use a focused 24° beam and deep anti-glare optical structure.

Used the angled reflector over our art wall instead of regular downlights
We have three framed pieces along one wall in the living room and the old recessed lights mostly lit the floor in front of them.
During the renovation we changed that section to the angled reflector version.
That worked much better for what we were trying to do. The light feels more intentional and there’s less spill across the rest of the wall.
Getting the fixture positions right mattered more than I expected. We mocked up the locations before cutting the ceiling and I’m glad we did because moving one of them a few inches made the artwork look much more balanced.

This is exactly the type of application the Angled Reflector is intended for.
LightingWill positions the angled CDG reflector for artwork, merchandise, feature walls and display lighting, where directional control and stronger visual focus are preferred. The series uses a 24° beam for focused architectural illumination.

Angled, curved or black reflector — which architectural downlight should you choose?
September 6, 2024
The CDG architectural downlight series uses the same focused 24° beam concept across several reflector styles, but the reflector shape changes how the fixture is best used.
Here’s the simplest way to choose between them.
Answered by LightingWill
Lighting specialist
Angled Reflector
Best when you want stronger directional emphasis. Recommended for artwork, merchandise, feature walls and retail displays.
Curved Reflector
Designed for smoother beam transitions and balanced architectural illumination. A good choice for hotels, offices, restaurants, reception areas and general premium interiors.
Black Reflector
Designed for maximum glare control and visual comfort. Best suited to galleries, museums, luxury retail, media rooms and upscale residential projects.
The US product family uses 90–140V, CRI>97 and 5CCT adjustable output, while EU models use 200–240V, CRI>95 and fixed 3000K / 4000K / 5000K options. All current CDG models use a 24° beam angle.

Black reflector or curved reflector — which one is better if glare is the main concern?
I’m choosing downlights for a media room where the ceiling lights will be visible from the sofa.
I’m deciding between the curved reflector and black reflector versions.
I don’t need the room extremely bright. My main concern is being able to sit down without feeling like I’m looking directly into the LEDs.
Is that where the black reflector makes more sense?
Answered by LightingWill
Lighting specialist
Yes. If minimizing perceived glare is the priority, the Black Reflector is the stronger starting point.
LightingWill positions the Black Reflector for maximum glare control and premium visual comfort, including galleries, luxury retail, executive spaces and refined residential interiors.
The Curved Reflector is more focused on balanced beam distribution and smooth transitions for general architectural lighting.

7W, 9W or 12W — should I choose by brightness or ceiling cutout first?
I’m replacing recessed lights in a hallway and already have ceiling openings from the old fixtures.
I was originally comparing the 7W, 9W and 12W versions based on brightness, but then I noticed the cutout sizes are different too.
Should I match the existing ceiling opening first and then choose the wattage?
Answered by LightingWill
Lighting specialist
For a renovation with existing ceiling holes, check the cutout first.
Across the CDG series, wattage and fixture size are linked. For example, current models include roughly:
7W — 2.2″ cutout
9W — 2.6″ or 3″ depending on reflector model
12W — 3″ cutout
Once you know which fixture physically fits, you can compare wattage, reflector type and color temperature within that size range.
Customer question
Lighting specialist
Is the 5CCT version useful if I already think I want 3000K?
I’m almost certain I want 3000K in our living room, so I’m wondering whether there’s any real advantage to buying the adjustable US version.
The paint and flooring aren’t finished yet, though.
Is it worth having the different CCT settings just in case the room looks different once everything is installed?
Answered by LightingWill
Lighting specialist
For a project where finishes are still being selected, adjustable CCT can be useful.
The CDG-US models allow selection between 2700K, 3000K, 3500K, 4000K and 5000K, giving you more flexibility to evaluate the light against wall colors, flooring, furniture and materials before settling on the final setting.
If the project specification already requires one fixed color temperature, the EU-style fixed-CCT approach is simpler.
Customer question
Lighting specialist
Can I use these with the TRIAC dimmer that’s already installed?
We already have a wall dimmer controlling the recessed lights in our dining room.
I’m looking at the CDG downlights and would rather not replace the switch if I don’t need to.
Are they meant to work with a normal TRIAC LED dimmer, or does the driver require something specific?
Answered by LightingWill
Lighting specialist
The current CDG architectural downlights are TRIAC dimmable and should be paired with a compatible LED TRIAC dimmer.
For example, the CDG-US Black Reflector is specified for approximately 10–100% TRIAC dimming, and EU CDG models also use TRIAC dimmable isolated drivers.
Because dimmer performance varies by model and load, we recommend confirming compatibility before completing a larger multi-fixture installation.
