Since 99% of the lights are LEDs, the electricity to run the show for the entire month is about $100. | sequenced the show using LOR, mixed the music/sound effects with Digital Performer, and filmed it using a 35' lift :) This is now my second year decorating. I built all the props using wood, metal, acrylic and corrugated plastic. I am a music/teacher director for a living (COVA Conservatory in Oakland and Centerville Presbyterian Church in Fremont), hence the massive instruments! If you look closely (especially during the Cantina song) the instruments are playing the real notes! Although the beams are powerful up close, they are a small percentage of real searchlights and are so widely dispersed that by the time they are up in the sky, they don't interfere with aircraft etc. The guitar is 17', the piano is 19' and the drums are standard. About 12,500 channels running around 100,000 lights. Merry Christmas everyone!
