However, in a "traditional" (tungsten-halogen) light fixture, the focus point position of a gobo is extremely hot, so these thin plastic films require special cooling elements to prevent melting. A lapse in the cooling apparatus, even for seconds, can ruin a plastic gobo in a tungsten-halogen lighting instrument.
A (used) gobo in a gobo holder. A pattern holder or gobo holder, is a metal frame designed to hold a gobo. [4] Gobo holders are placed inside a fixture through a specifically designed opening, which places the pattern directly in the focal plane of the fixture.
Field angle is the angle of the beam of light where it reaches 10% of the intensity of the center of the beam. Most manufacturers now use field angle to indicate the fixture's spread typically in this series (5°, 10°, 19°, 26°, 36°, 50°, 75°, 90°). Older fixtures are described by the width of the lens x focal length of the instrument ...
Strip lights, also known as cyclorama or cyc lights (thus named because they are effective for lighting the cyclorama, a curtain at the back of the stage), border lights, and codas (by the brand name), are long housings typically containing multiple lamps arranged along the length of the instrument and emitting light perpendicular to its length.
