We get many questions about the differences between Glass Gobos and Steel Gobos.
With a steel gobo, think of it as sort of like a stencil- The design is being cut through the metal, which would require tab support lines to keep the image intact- holding in the centers of letters, things like that. Steel gobos project white light or a single color by using a gel. Glass gobos employ a dichroic coating process on top of the glass, so they do not require support tabs, and can be muti-color. The cost of glass is almost 4 times as much as the cost of steel, so it’s important to take into consideration not only your personal aesthetic, but also your budget concerns.
