Ryan Killebrew from Harvest Community Church in Mesa, Arizona brings us these cool light stacks.
To create these bad boys the team spray painted plywood back and assembled the light tower boxes. They lined the openings with white light diffusers from fluorescent light fixtures (rectangle lights from offices). They produced four smaller rectangles from each light diffuser.
To light the boxes they placed one LED Par64 in each box. To keep the light from escaping the top they used black foam board tightly fitted into the tops.
Each tower was created with separate segments to let them easily move the pieces in and out of the movie theatre they meet in.
They kept the costs down by reusing plywood from previous projects. So the only cost was liquid nails, paint and the light diffusers.
