15 trash cans at Ikea (for $1.99 each) and drilled holes in the bottom. He then attached an Ikea lamp socket set inside of the trash cans ($4.99 per socket set). Then he hung the lamp sockets from the truss at random lengths. Each one has a trash can lamp has a 60-watt bulb inside and is wired to a dimmer. To add a little extra light he used six LED par cans on the sides of the truss to add color. The total cost for the set was $105.
