The par cans are good, they are lightweight because of the new powersource, the light output is almoust double comparing to a 5mm par can, the colors are acurate, working with them on dmx is real simple, on sound active mode they strobe to fast, but this is becuse of the high sound presure so i recomend to use them on dmx mode. From the jumper configuration you can set them to do any color even fade through colors, this is really helpfull for uplighting. Overall i use 40 of these par cans now for over 2 years and I really am satisfied, they do a great job.
