Key Features and Technical Specifications
Energy Efficiency and Cost Savings
One of the most compelling reasons architects and builders across India are adopting the HLA 3721 481918 is its exceptional energy efficiency. At just 14W, this fixture consumes significantly less electricity than traditional halogen or incandescent wall lights. For a typical Indian commercial building operating 12 hours daily, switching to this LED solution can reduce lighting costs by 70-80% compared to older technologies.
Consider this practical example: If your building has 100 wall lights operating 4,000 hours annually, switching from 100W halogen to 14W LED would save approximately 34,400 kWh yearly. At an average commercial electricity rate of ₹8-12 per unit in major Indian cities, this translates to annual savings of ₹2,75,000 to ₹4,12,800.
