Lighting Efficiency: A Practical Case Study
The Science of Luminous Efficacy
The Illuminating Engineering Society (IES) highlights the importance of luminous efficacy—the ratio of light output to power input:
- Incandescent Bulb: 15–20 lumens per watt
- LED Bulb: 80–100 lumens per watt
Real-World Savings Calculation
Detailed Efficiency Analysis
Scenario: 200 sq. ft. Lighting Requirement
Illumination Standard: 125 lumens/m² (2313 lumens Required)
Comparative Technology Assessment:
- Incandescent Bulb Scenario:
- Wattage: 154 W (W=2313/15)
- Luminous Efficacy: 15 lm/W
- Total Lumens Required : 2,313 lumens for 200 Sq.Ft Area
- Energy Efficiency: Baseline
- LED Bulb Scenario:
- Wattage: 27 W (W=2314/85)
- Luminous Efficacy: 85 lm/W
- Total Lumens Required : 2,313 lumens for 200 Sq.Ft Area
- Energy Efficiency: 82.46 % compared to Baseline
Annual Energy and Cost Savings
- Power Reduction: 127 W (154 W – 27 W)
- Annual Usage: 4,380 hours (50% of year)
Calculations:
- Annual Energy Savings: 127 W × 4,380 hours = 556.26 kWh
- Annual Cost Savings: 556.26 kWh × $0.03 = $16.68 per fixture
Scalability Impact: In a multi-story building with 300 x $16.68 per fixture suites, potential annual savings could reach $5,006.
