Industrial Lighting ROI Calculator
Estimate retrofit savings for a warehouse or industrial facility. Set fixture watts, operating days and unit cost to compare electricity use and payback.
Estimate retrofit savings for a warehouse or industrial facility. Set fixture watts, operating days and unit cost to compare electricity use and payback.
Adjust facility parameters, fixture specs and operating schedule. Results update in real time. No sign-up required.
Enter your facility dimensions, current lighting and LED replacement details.
Total floor area of the facility to be retrofitted.
Record the mounting height for the layout review. Height alone does not determine the required fixture wattage.
Selecting a type auto-fills the wattage field below.
Watts per existing fixture (editable if custom).
Total fixtures to be replaced with LED.
Watts per LED high-bay fixture delivering equivalent lux.
Single-shift plants ~12h, continuous operations 24h.
Operating days per year (5-day weeks ~260, 24/7 ~365).
Use your site’s electricity tariff.
Factory-direct LED high-bay price (installation excluded).

This calculation compares two equal-count lighting systems on the same operating schedule. Facility area and ceiling height provide project context; the entered watts and fixture count determine electricity savings.
Fifty 400 W fixtures replaced by 150 W LEDs, running 12 hours/day for 300 days/year, save 45,000 kWh. At $0.12/kWh, savings are $5,400/year. A $120 unit price gives a $6,000 purchase cost and about 13.3 months’ payback.
Background on fixture efficacy, light quality and lifetime. The planning assumptions shown here are specific to this tool.
Side-by-side metrics for your facility. All values update live with the inputs above.
| Metric | Current | LED | Savings |
|---|---|---|---|
| Total Power Load | 0 W | 0 W | 0 W |
| Annual Energy Consumption | 0 kWh | 0 kWh | 0 kWh |
| Annual Energy Cost | $0.00 | $0.00 | $0.00 |
| Annual CO2 Emissions | 0 kg | 0 kg | 0 kg |
| 5-Year Net Savings | After initial investment | $0.00 | |
CO2 comparison assumption: 0.707 kg/kWh. The tree comparison uses 21 kg/year; both are illustrative, not site-specific reporting values.
Input your facility area, ceiling height, current fixture type, wattage and the number of fixtures to replace.
The calculator instantly computes annual savings, payback period, energy reduction, CO2 avoided and 5-year net returns.
Send a floor plan, rack heights, task areas, and proposed fixtures for a layout and quote.
For example, replacing fifty 400W fixtures with 150W LEDs saves 45,000 kWh over 3,600 operating hours. Multiply by your tariff for the annual electricity saving, then check that the new layout provides the required light.
Payback depends on the installed cost and annual savings. Longer operating hours generally increase electricity savings, but labour, controls, and access costs can also be significant.
Use mounting height with the task light level, beam distribution, room geometry, and obstructions to select fixtures. A wattage recommendation based on height alone cannot establish the required illuminance.
Send the facility plan, mounting height, task requirements, and operating schedule when requesting a layout. Ask for the proposed fixture photometry and a report showing the calculation assumptions.
Share your fixture schedule, operating hours, mounting heights, and project location. Ask for model specifications and pricing to complete the budget.
