Scott Chamberlain from First Baptist Church Harvester in St. Charles, MO brings us this wall of radiating squares. (Originally posted June 2013)
They wanted to do a major stage redesign to debut on Easter. They had a beige stage back wall and ceiling and had it painted black a few weeks prior. With a blank slate and after getting a bit of inspiration from CSDI and seeing what others had done with Coroplast, they decided to do individually LED backlit Coroplast 3’x3′ panels in a semi-random grid on the back wall combined with staggered bottom LED light truss.
Their budget was $8500 which included purchasing a few sticks of additional trussing and a few more Colorblast 6 light fixtures.
For the LED panels, they used clear Coroplast for the front and white as to refract light in the back, and made a 3’x3′ square out of one-inch wide J-channel to affix the Coroplast. After the front clear Coroplast panel was mounted to the J-channel, RGB LED strip-lights were installed in the valley of the channel around all four sides. Each LED panel had a home run back to one of the six 24 channel 12 volt DMX controllers operating the entire back wall. In total there were 47 panels and 141 DMX channels used for the LED panel wall. Then they used the staggered 10 ft truss to add a bit of dimension to the design.
Each panel took about 20 minutes to construct – including the installation of the LED strips – and 30 hours to hang wire and test the entire wall. Their biggest challenge was wiring and box placement. Each box could be no further than 16 ft from its controller and having a more traditional style auditorium made pulling wire a challenge.
