In Singapore's commitment to becoming a sustainable smart city, energy efficiency has become a critical factor for businesses and homeowners alike. LED panels represent one of the most effective ways to reduce energy consumption while maintaining superior lighting quality. This comprehensive guide explores how to maximize energy efficiency with LED panel installations.
Understanding LED Energy Efficiency
LED panels are significantly more energy-efficient than traditional lighting technologies. The efficiency of LED panels is measured in lumens per watt (lm/W), which indicates how much light output is produced per unit of electrical power consumed.
Efficiency Comparison
- LED Panels: 80-200 lm/W
- Fluorescent Tubes: 50-100 lm/W
- Incandescent Bulbs: 10-20 lm/W
- Halogen Lamps: 15-25 lm/W
