PRISMO™ animates your still pattern and it multiplies the image either three or five times depending upon your prism choice. The prism speed can be varied by plugging the PRISMO™ into any dimmer or using the sliding switch on its 6-step power supply. There's also an optional in-line speed control for more precise control. PRISMO™ easily fits into the 6 1/4 inch gel slot of your ellipsoidal spotlight with your color frame.
