Frequently asked
Cost Savings in the Indian Context
When implementing LED architectural wall lights in Indian commercial or residential projects, the financial benefits are substantial. Traditional 50W halogen wall lights consume approximately 10 times more energy than the 5W LED setting of the HLA 3681 481227. For a typical commercial building in Bangalore with 100 exterior wall lights operating 12 hours daily:
Traditional Halogen: 50W × 100 lights × 12 hours × 365 days = 21,900 kWh annually
LED at 5W: 5W × 100 lights × 12 hours × 365 days = 2,190 kWh annually
Annual Savings: Approximately ₹1,75,000 to ₹2,25,000 (at ₹8-10 per kWh)
Compliance with Indian Building Codes
The Energy Conservation Building Code (ECBC) 2017, adopted by various Indian states, mandates energy-efficient lighting solutions. LED architectural wall lights like the HLA 3681 481227 help projects meet these requirements, potentially qualifying for green building certifications such as LEED or GRIHA ratings, which can enhance property value and marketability.
