SILVERSUN illuminates Santander Bank at the center of Madrid. The offices were located in an old building with conventional lighting. This system was conformed by 800 conventional downlights with two bulbs of 26W, involving low quality of light and high maintenance costs -bulb replacement every two years. For this project 300 SILVERSUN panels with 36W had been installed, achieving a much greater energy efficiency (from 60 to almost 100 lumen per watt), 50% lower maintenance costs and around 20% less on the electricity bill.
Before: 800 Downlights 2x26W
After: 300 Standard Panels 60x60 36W
