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:

  1. 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
  2. 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.
