During an energy audit of our client’s process plant lighting system, StrangersEnergy discovered that, although production processes were managed through a Programmable Logic Controller (PLC), the lighting system was not integrated—resulting in lights operating 24/7 without need.

To address this, StrangersEnergy delivered a cost‑effective and highly efficient lighting optimisation solution:

PLC‑Integrated Lighting Control

We engineered a custom circuit that links the lighting system to the existing PLC. This enables lights to automatically switch ON at 17:30 and OFF at 06:30, eliminating unnecessary round‑the‑clock operation. This approach was significantly more cost‑effective than installing centralised timers or photocells.

LED Upgrade for Maximum Efficiency
We recommended replacing the existing HPS fittings with high‑efficiency LED floodlights. A detailed cost‑benefit analysis demonstrated substantial long‑term energy and maintenance savings

Improved Illumination Through Preventive Maintenance

We incorporated light-cover cleaning into the preventive maintenance schedule to enhance illumination levels and prolong fixture performance.
