Ignialight will take part in a talk to explain the success story of the LED lighting fitted in the opening of the tunnel in Madrid's M40 ring road.The installation enabled the old high pressure sodium vapour lamps to be replaced by LED technology, specifically, a 300 W TLED for the backup lighting and a 75 W XLED for the permanent lighting. The results have confirmed that Ignialight's LED technology exceeds the demanding requirements for tunnel entrance lighting.
