Barcode Night Club was built in a disused brick Victorian railway arch in Vauxhall, South London by Woods Bagot. By Using LED light, the Architect claim that the system consumes “less electricity than the power used to boil a kettle” Because the LEDs give off very little heat, much less AC is required to cool the building in summer. In this case, Night Club atmospher doesn’t need a lot of light-power. It hasn’t been tried in general interior like retaurant .As far as it gives comfortable interior atmosphere for the people within, I thing It will be a new trend of interior lighting design.
