Colored Signature Series gobos ("lithos") are made using Rosco's premier quality Permacolor dichroic coatings. The rich colors are etched with precise designs created by some of the leading lighting designers working today. Use in automated lights or ellipsoidal luminaires, static or rotating, to create exciting, complex lighting effects.

Spectrumgobos can withstand temperatures found in modern ellipsoidal luminaires ("lekos") that use the new generation of sub-1000 watt lamps and a dichroic reflector. Moving lights using metal halide sources up to 1200 watts are generally compatible as well. However since some luminaires generate an abnormal amount of heat, it is advised to check with Rosco to see if your fixture is suitable for use with Spectrumgobos.
