Hedensted town replaces Avenue Deco with Avenue F LED to reap energy savings
Hedensted is a small Danish town on the outskirts of Vejle. Like many towns, it has been expanded with large residential areas around the original town centre, along with industrial estates to the south and west.
Renovation of a prime residential area combined with a high agenda to replace all mercury lamps to reduce energy use and comply with future regulations meant a replacement for the old Avenue Deco HME lanterns was required. In keeping with the area’s design guidelines, the Avenue F LED post top lantern mounted on the existing poles offered the ideal solution.
LED meets the high performance specification
Avenue F LED features a prismatic crown for reduced glare as well as a distinctive modern yet elegant aesthetic. Its state-of-the-art LED system ensures performance, comfort and efficiency, along with a unique light signature to show the town in a fresh new light.
Avenue F LED is equipped with the Bi power dimming facility as standard to easily maximise energy savings. The Bi power system reduces energy consumption and light output by 50% for eight hours during the quietest part of the night. Using a simple on/off switch located on the top of the gear tray, nighttime power reduction can be activated and deactivated as and when required.
Bi power reduces energy consumption with no effect on colour rendering or colour temperature. It will also extend the lifetime of the LED by reducing the power and in turn, the stress and heat it encounters.
Avenue F LED is part of a wider family with coordinated columns and a wall version, which offers flexibility and consistency for future lighting schemes and refurbishments. For more information, go to www.thornlighting.com/AVFL
Key Facts
Old installation: Avenue Deco HME 80W including ballast
Annual energy consumption: 36,000 kWh
Annual energy costs: 72,000 DKK
New installation: Avenue F LED 20W
Annual energy consumption: 5,110 kWh
Annual energy costs: 10,220 DKK
Total annual energy savings
- 86%
- 30,890 kWh
- 61,780 DKK
The above is a theoretical calculation. In practice savings will vary throughout the year. In the winter the light will be on at 100% for longer periods than during summer, where Bi power dimming will at times be activated for the entire period. Generally the lighting will be on for approximately 4,000 hours a year.
