Lighting energy savings are not just about replacing old lamps with LEDs. Real cost reduction combines power, operating hours, maintenance, downtime, controls and lighting quality.
This page can cover industrial LED lighting energy saving, factory lighting retrofit, warehouse lighting ROI, DALI, motion sensor and 150lm/W naturally.
Build the energy baseline first
Count fixtures, measured power, hours, tariff, failures and maintenance cost.
- Separate zones
- Record legacy wattage
- Measure current lighting
Then optimize products and layout
High efficacy, suitable optics and less wasted light are stronger than simply lowering wattage.
- Check efficacy
- Check beam distribution
- Check uniformity
Add zoning and sensing
Warehouses, cold rooms, roads and parking areas can reduce empty-zone energy through zoning, sensors, schedules or dimming.
- Map people and vehicles
- Set minimum output
- Keep manual fallback
Review payback by cash flow
Payback should include electricity, maintenance, downtime, spares, installation and commissioning.
- Use conservative inputs
- Pilot a sample area
- Review periodically
