The China Lights , an exhibit of Chinese Lanterns, is located in the Botanical Gardens in City Park, New Orleans.This is a touring exhibit which has been in many places around the world. Before coming to New Orleans, it was in Rotterdam. There are dozens of lamps and structures covered with silk and with lights either inside or around the outside. They are lit up at night although I was unable to see them then.
Here are two links that provide some further information
