Professionally made on CNC cutter and wired up over 3 channels to allow full DMX control. Channel 1 controls the red border of each letter, the each of the bulbs is wired on an alternate channel allowing the letters to be fully programmable. These cost over £6k to have made and have been used once for a corporate event. We have now sold the part of the business which uses this kind of items so they are surplus to requirement. Sold with all wiring and DMX receivers. The receivers do have some built in programmes so could be used that way, or can be controlled through a lighting desk (not included).
