Graitery tunnel (Switzerland)

The Graitery tunnel is a brand new tunnel in Switzerland with a length of 2,462m. The construction of the tunnel started in November 2006 and will be completed at the end of 2013. Our reliable QL induction lighting systems will be used as emergency exit lights. Forty-nine QL 55W systems will be installed in Luxo 1 and Luxo 2 luminaires from Hugentobler Spezialleuchten later this year.


QL induction lighting was chosen because the customer is very satisfied with several QL installations in other projects.
