Steel Patterns, or gobos, are widely used by designers in theatre, film, photography and television to create atmosphere, project scenery, and generally enhance the visual impact of their lighting. To insure design integrity the patterns are etched using a precise double-sided process on stainless steel. The result is durable, high quality patterns which will withstand the extreme heat at the gate of ellipsoidal spotlights. Conceived by some of the world’s leading lighting designers, the Rosco range presently includes over 1000 standard steel gobo designs.
Steel gobos can withstand the heat from virtually any modern luminaire, at least for a short while. In luminaires under 1200 watts, a steel gobo can be expected to last for months or longer of typical theatre usage. It is common for the gobo to discolor and possibly warp due to the intense heat but the integrity of the design will remain intact. In some designs with extremely fine line details, excessive heat may damage these fragile elements prematurely. When used in luminaires over 1200 watts, the lifespan will be reduced to some extent, depending on the heat and focus of the lamp.
