In short
Choose architectural downlights by beam angle, glare control, output, colour quality, cut-out size, IP rating and controls, matched to the space and ceiling.
Downlights are the most common recessed fitting in commercial buildings, but quality varies enormously. Architectural downlights put light where it is needed with minimal glare.
What makes a downlight "architectural"
- Deep-set or well-shielded light sources for visual comfort
- Accurate optics and a choice of beam angles
- High colour rendering
- Clean, slim trims
Key choices
Beam angle
Narrow beams accent features; wide beams give general light. Most offices use medium to wide distributions.
Glare control
Look for low UGR values and deep recessing or louvres where people look up often.
Shape
Circular downlights are the default. Square downlights, like Cinca Square, suit rectilinear architecture.
Fast-track projects
For large Cat A floors, reliable downlights with short lead times, such as Rega or Cinca, keep programmes on track.

What is an architectural downlight?
A recessed downlight designed for precise light control, low glare and high colour quality, often with clean, slim trims.
Are square downlights as efficient as round ones?
Yes. The shape mainly affects appearance; efficiency depends on the optic and LED module.
