I am using a power spot 250 with a show designer 1 control. When I switch from scene to scene how do I get the light to black out while it goes to the next position and then come on again.

you could just program a blackout scene in the sequence befroe you want it to be on. just put it on a short hold time or fade time. also im not too sure about the power spots but in some lights there is whats called a "vector mode" which if u have that value selected it will black out when a either pan or tilt motor is moving or even color/gobo wheels moving. it is a cool effect, but again i didn't see it in the values of the power spot 250. peace! welcome to the forums. jingles.
