Not too big, 20 gobos, 15 colors, lazer ... It is very comprehensive and benefitted a great rate attractions with, and a very successful design, low I admit the scans of "MARTIN". There are black and silver. There are two MODELS 1 (lamp Halogne) 2 (discharge to lamp), c the only diffrence. I am very satisfied. It is of course DMX controllable, and if necessary, he démerder alone with the music. A beautiful machine. A buy !!!!!!!!!!!!!!
