The complexity of large space introduction cannot be solved simply by "buying LED fixtures".
3.1 Complex lighting environment
Large buildings contain several areas with different needs:
- lobby and atrium
- Corridors and circulation spaces
- Retail area
- Restaurant and lounge
- Meeting room
- Facade
- Artwork and architectural features
Each area requires a unique layer of lighting:
ambient sound + accent + task + swipe + indirect.
3.2 High brightness and visual comfort requirements
Professional architectural design requires:
- High CRI (90-95+)
- Stable light color and output
- Beam accuracy (10° / 24° / 36° / 60°)
- Excellent glare control (UGR < 19 or strict cut-off system)

3.3 Strict supply chain demands
Large projects may require:
- 1,000–20,000+ lamps
- Long-term delivery plan
- Multiple installation stages
- Strict color classification consistency
Any supply chain delays can affect construction schedules.
3.4 Integration with Control System
Large buildings require a centralized automation system:
- DALI
- 0-10V
- Kasambi
- DMX (for façade or dynamic scenes)
- BACnet integration

3.5 Engineering complexity
Installation work requires structural coordination:
- flush mounting
- Housing that meets ventilation duct standards
- Fireproof ceilings
- Custom profiles
- Electrical coordination with other mechatronics majors
