Planning for Lighting Control
Decisions made during the electrical design phase determine which systems are possible.
Before first fix, you must decide which approach you are taking:
- Conventional Lighting: Standard wiring, no automation.
- Smart Switching: Standard wiring + neutral wires at every switch.
- Lutron / KNX: Specialist bus cabling and centralised dimming modules.
- Hybrid Systems: A mix of wired and wireless control.
Each option has different implications for cabling, DB space, and total cost.
Cabling Requirements
Wired systems require specific cabling topologies that differ from traditional electrical wiring.
Circuit Design and DB Space
Smart lighting requires more physical space than conventional systems.
Independent Returns
Each lighting circuit should return independently to the DB for maximum control.
Module Space
Ensure your Distribution Board (DB) has adequate DIN rail space for control modules.
Ventilation
Dimming modules generate heat. Proper airflow in equipment cupboards is essential.
Automation vs Reliability
Design for when you aren't there.
Automation should improve daily life and reduce friction. However, over-automation often causes issues when owners are travelling or away:
- Systems must behave predictably for guests or maintenance staff.
- Manual overrides (physical switches) should always work.
- Remote access must be secure and reliable.
