Dear Mr. Chevalier,
Dellux delivered and commissioned the LED Tunnel Lighting system for the Tunnel Schmiicke, Germany in August 2008.
The LED lighting installation works now for 6 years without interruption. maintenance or repair. No luminaries were replaced in these 6 years.
The system is working according the design criteria, electricity use is within the margin according the calculations. We are satisfied.
The (remote) control system is seen as an important part in managing the ex-act correct light level and the remote monitoring is good.
