It is a very nice little scanner dmx 4 channel (pan, tilt, shutter / gobo and strobbo)
good is a small lamp 100w is therefore important to provide hope to enlighten bercy lol, but 135 is really a good deal.
it is quiet, fast, short I like it and then it has the advantage that price I show my 8 scan, and it makes better than more expensive 2 Scanner
