LED Street-Lighting In Finland

Golden DRAGON LEDs in first LED street-lighting in Finland

After extensive testing, the Levi ski resort in Kittilä is to be the first district in Finland to install LED street-lighting.

The system comprises 64 Starium Dragon 60 luminaires from EasyLed Oy, each equipped with 60 Osram Opto Semiconductors Golden DRAGON LEDs fitted with oval lenses (3840 LEDs in total). The LED street-lamps consume just 41W, cutting energy costs for the local authority and, together with minimal maintenance requirements, leading to a payback period of just 4.5 years, it is reckoned.

“We were particularly persuaded by the excellent color rendering [with a color temperature of 5600K, similar to natural light], the vibration resistance of the light sources, and the freedom to create any luminaire designs thanks to the small size of the LEDs,” says EasyLed’s product development director Mika Nummenpalo. “The stability of the luminous flux and the ideal distribution of light with no scatter – and therefore no light pollution – were key factors in the decision to install LEDs,” adds Ari Tiilikainen, a lighting designer at Lite-Design. “Thanks to sophisticated thermal management, we were able to give the luminaires a modern low-profile design, as requested by the local authority,” he adds.

“The Starium Dragon 60 offers the best luminous efficacy and therefore the greatest potential savings,” reckons Jari Kinnunen from the Technical Department in the Kittilä authority.
