In 2001, one of the world’s largest home furnishings chains opened a new store in Netanya, Israel. It offers 6,500 home furniture items and design accessories, which are constantly renewed and affordably priced. The new store also provides inspiration, with a variety of design ideas for organizing the home and improving daily life, along with showrooms that display furniture and accessories in a home setting.
The company’s vision is to offer a wide range of well-designed, functional home furnishing products at reasonable prices. It invested approximately $30 million to build its new store, which includes its Middle East headquarters and warehouse facilities. Sales at the Natanya store have skyrocketed since it opened, with 25% sales growth over the last three years.
Original Situation
The Netanya store’s 23,000 square meter display area was illuminated with several hundred 400W Metal Halide lamps with magnetic ballasts. The light output achieved by these lamps reached an average of 90 lux, with annual power consumption of 329,639 KWH.
Metrolight proposed retrofitting the store’s system with the Metrolight Smart Electronic Ballasts for HID™ system to increase illumination.
The Solution
The store’s management selected the Metrolight Smart Electronic Ballast for HID™ solution, which would increase the average illumination while reducing maintenance costs and saving energy. The Metrolight solution included retrofitting the system with 400 Watt Metrolight Smart Electronic Ballasts for HID™, all dimmed to 300 Watts and connected to the Metrolight Diagnostic™ software system.
The Result
The store reduced maintenance costs and gained energy savings of over 30%, dramatically improving light output despite using lower wattage lamps.
