A lower meter total does not by itself demonstrate improved efficiency.*\n\n## The Efficiency Stack\n\nLighting efficiency is achieved in layers, in this order:\n\n1. **The light source** — LED replaces HID/fluorescent: 50–70% lower consumption, longer life, instant restrike, and better controllability. The retrofit decision is usually economic on energy alone, plus the maintenance savings of a 50,000–100,000 hour lifetime.\n2. **Lighting design** — the right luminaire, mounting height, and spacing for the task's illuminance level (EN 12464-1 defines values by task); over-lighting is the most common silent waste.\n3. **Controls** — switching and dimming that match the light to the presence and the daylight: the layer this article focuses on.\n4. **Maintenance** — cleaning and group relamping keep the installed performance; a dirty luminaire loses 20–30% of its output silently.\n\n## Control Strategies\n\n| Strategy | Principle | Typical savings vs uncontrolled |\n| --- | --- | --- |\n| Occupancy detection | Lights on only when presence is detected (PIR/microwave sensors), with time delays tuned to the area's traffic. | 30–70% in intermittent-use areas (warehouses, corridors, washrooms). |\n| Daylight harvesting | Dim or switch luminaires near windows/skylights based on ambient light sensors. | 20–40% in perimeter zones with daylight. |\n| Scheduling | Time-based scenes per shift: production on, breaks dimmed, off-hours off (with safety lighting maintained). | Large in off-hours — the biggest single saving for 24/7 facilities with quiet periods. |\n| Constant light / dimming | Luminaire dims as it ages to maintain constant illuminance — extends life and saves energy. | 5–10% plus longer lamp life. |\n\nSafety is a constraint, not an option: emergency lighting (EN 1838) must remain independent of the general control system, and areas with defined minimum illumination (safety-relevant walkways, control rooms) get their floor levels guaranteed by design — controls reduce light *above* the requirement, never below it.\n\n## Networked Lighting Control\n\nModern industrial lighting is increasingly *networked*: DALI-2 (the standard for addressable lighting control), wireless mesh (Zigbee, Bluetooth mesh, or vendor systems), or IoT lighting where luminaires are nodes on the building network. Networked lighting gives the plant what a pile of standalone sensors cannot:\n\n- Central management: scene programming, scheduling, and per-area override from one software (or the BMS).\n- Feedback: real energy data per zone, fault reporting (a failed driver reports itself), and occupancy data that doubles as building intelligence.\n- Flexibility: reconfiguring zones after layout changes is software, not rewiring.\n- Integration: the lighting system connects to the BMS/SCADA for coordinated control (shift schedules, emergency modes, energy dashboards).\n\nFor the automation department, the integration question is standard: the lighting controller exposes its data (energy, status, alarms) over the same protocols the plant already uses (Modbus, BACnet, or MQTT for IoT lighting) — define the interface at procurement, not after.\n\n## Implementation Guidance\n\n1. **Audit first** — map the current lighting: fixtures, hours, zones, and the off-hours baseline (a night walk reveals everything).\n2. **Retrofit by zone priority** — start with the highest hours × wattage zones; the payback calculation per zone is trivial with LED economics.\n3. **Controls for the intermittent zones first** — warehousing, storage, and maintenance areas deliver the fastest occupancy-control savings.\n4. **Standardize on one protocol** — one control platform (DALI-2 or a single wireless ecosystem) keeps commissioning and spares simple.\n5. **Commission properly** — sensor placement and time delays must match the actual movement patterns; a badly tuned occupancy sensor causes complaints and gets bypassed — which kills the savings.\n6. **Verify with metering** — compare consumption before/after per zone; the lighting dashboard shows the savings continuously, which is what justifies the next retrofit round.\n\n## Summary\n\nIndustrial lighting efficiency is LED first, then controls: occupancy detection for intermittent areas, daylight harvesting for perimeter zones, scheduling for off-hours, and networked management for visibility and flexibility. Treat it as an automation project with a fast payback: audit the zones, standardize the protocol, commission the sensors properly, and verify with energy data.
