Scan using msd 250 lamp with good light output, and ... pretty quiet.
This servo is controlled by 6 DMX channels: 1-Pan, 2-Tilt, 3-color, 4-Gobo, 5-Rotation / Orientation Gobo, 6-Shutter Strobe Dimmer. The motors are of a relatively robust quality. Mirror movements are quite flexible. Many possibilts for an inexpensive source device operates msd in a good light output!
Gobos are changing very fast. I advise you to replace the first gobo by a home-made: small tole dcentr pierces a hole. This manufactured gobo "house" allows reduce the beam aperture, but also, it gives a very nice effect and dancing when rotating.
BMOL: The gobos are not super sharp, but they are very correct, adjustable focus manually. You can not request to have the superb projection quality of much more expensive devices. Personally, I had my scn-900 800 pice, new, with the lamp!
In short, good workmanship, good quality of the components. Beautiful colors ... Very well discomobile with its many possibilities for smaller shows or concerts it holds up.
