The Complete Guide to Architectural Facade Lighting
Everything a lighting designer or architect needs to know about specifying, installing, and maintaining modern facade lighting systems.
Facade lighting has evolved from simple floodlights into sophisticated systems capable of turning entire building envelopes into dynamic canvases. This guide covers everything from initial specification through to long-term maintenance.
Why facade lighting matters
The exterior of a building is its first impression — at night, that impression is entirely controlled by light. Well-designed facade lighting can:
- Define architectural character after dark
- Reinforce brand identity for commercial properties
- Create civic landmarks in urban environments
- Enable dynamic, programmable media displays
Choosing the right system
Linear grazing vs. projection
Linear grazing fixtures mount close to the building surface and skim light across it, revealing texture and depth. Projectors are mounted further away and cast broader washes of light.
For textured stone or brick facades, linear grazing will dramatically emphasise the materiality. For smooth glass or EIFS, projection gives more even coverage.
IP rating considerations
For any outdoor installation, IP65 is the minimum acceptable rating. For submersible or high-pressure washdown applications, IP67 or IP68 is required.
PIXL Lighting tip: Our outdoor products are rated IP65–IP68. Always specify one IP rating above the minimum requirement for the environmental conditions.
Media facade systems
A media facade takes this further — the building surface becomes a display medium. Key considerations:
- Pixel pitch — smaller pitch = higher resolution but higher cost per m²
- Viewing distance — minimum comfortable viewing distance is roughly 100× the pixel pitch
- Run length — longer runs reduce the number of control units needed
- Fault tolerance — critical for installations where downtime is unacceptable
PIXLCore™ fault tolerance
Traditional daisy-chained systems fail downstream of any single fixture failure. PIXLCore™ maintains continuous operation across the full installation even when individual fixtures fail — the first technology of its kind to achieve this at scale.
Specification checklist
Before submitting a specification:
- Confirm IP rating against site environmental conditions
- Calculate run lengths and number of control units required
- Specify colour temperature and CRI for consistent rendering
- Confirm certifications required (ETL, UL, DLC, CE)
- Coordinate with structural engineer for mounting loads
- Review local light pollution ordinances
