ROI of Decorative Lighting: A Cost-Benefit Analysis for Businesses
Share
The CEO and finance director look at the figures. Here is how to present the ROI of an investment in decorative LED lighting for a business, with quantifiable data and consistent qualitative factors.
The components of ROI
1. Energy savings (quantifiable)
Replacing 72W fluorescent panels with 40W LED panels:
- Savings: 32W per panel
- For 20 panels, 8 hours/day, 250 days/year: 1,280 kWh/year
- At the business rate (€0.18/kWh): €230/year
- Over 10 years: €2,300 in electricity savings
2. Avoided maintenance (quantifiable)
- Fluorescent tubes: €3/unit, 2 replacements/year/panel, 20 panels = €120/year
- Labor (ladders, scaffolding): €200 to €400/intervention, 1 to 2 times/year
- Total avoided maintenance: €320 to €520/year
3. Quality of working life and absenteeism (partially quantifiable)
A World Green Building Council study (2014) estimates that improving indoor air quality and lighting can reduce absenteeism by 10%. For 10 employees with an average annual cost of €35,000, reducing absenteeism by 1 day per employee represents approximately €13,500. Even half a day represents €6,750.
4. Brand image and attractiveness (not directly quantifiable)
An open-plan office with decorative LED panels is photographed during site visits, posted on LinkedIn, and mentioned in job offers. The value is real but difficult to quantify directly.
Summary calculation over 10 years (20 panels)
| Item | Amount over 10 years |
|---|---|
| Investment (20 decorative panels at €129) | - 2 580 € |
| Energy savings | + €2,300 |
| Avoided maintenance | + €3,200 to €5,200 |
| Minimum net gain (excluding quality of working life) | + €2,920 to €4,920 |
FAQ
Is decorative lighting tax-deductible?
LED panels (decorative or standard) installed in professional premises are recorded as fixed assets or deducted as expenses, depending on their value and use (improvement versus maintenance). A purchase costing less than €500 excluding VAT per unit may be expensed directly. Consult your accountant to ensure the correct classification for your situation.
Can public grants be used to finance lighting replacement?
Yes, several schemes are available: Energy Savings Certificates (CEE) can provide a grant for replacing fluorescent lighting with LED (standardized operation BAT-EQ-127). Ademe and certain regions also offer energy-efficiency grants for SMEs. The amount depends on the number of kWh saved.
What is the average return on investment of a decorative LED panel?
For a Sunshine Panel decorative LED panel (€129, compared with €89 for a standard panel), the additional €40 has no direct energy ROI (consumption is identical). The ROI of the decorative component is indirect: its impact on quality of working life, brand image, and the attractiveness of the space. These factors are difficult to quantify but are documented: reduced turnover, easier recruitment, and improved customer perception.
