We have spent the first part of the summer with a black stage. A couple of weeks ago I added a 20′ X 10′ cross made out of light bulbs. The original concept was to use standard 100 watt bulbs. After thinking about it, I decided to go with a 12″X 1″ showcase bulb (I only paid $3.25 per bulb from a local supplier). The showcase bulbs added a very sculptural effect to the cross. The sockets, purchased from Ikea, come with a 15′ long cord on them. I laid a 10′ section of Unistrut on the stage floor, measured out the cross and attached the cords with black zip ties.
