Gobo Holders

With the breadth and depth of gobos available, it is important to choose the gobo holder that is appropriate for your luminaire (most luminaires must use a specific size gobo) and for the type of gobo you are using. Some gobos are thicker than others and require a special holder to accommodate it.

GoboPlus supplies gobo holders to fit most luminaires in current use. When selecting a gobo holder, care must be taken to ensure that both the overall dimensions of the holder and the size of the gobo it will accept, are compatible with the lantern used.
