About the Altman FC-1-CE 1500v Focusing Cyc Fixture Lights
The Altman FC-1-CE is a professional 1500-watt focusing cyclorama fixture, a specialized theatrical luminaire designed for the seamless illumination of large, continuous backdrops known as cycloramas (or "cycs"). Its primary function is to cast a smooth, even wash of light across the entire vertical surface of a cyc, eliminating hot spots, shadows, and color variations to create a uniform field of color or a convincing illusion of sky. The fixture achieves this through a unique asymmetrical reflector and lens system housed in a compact, yoke-mounted steel body. This optical system is engineered to blend the light from a powerful single-ended tungsten-halogen lamp, distributing it evenly from the top to the bottom of a tall cyc cloth. Precise focusing knobs allow the beam edge to be softened or hardened and the overall field to be adjusted, enabling the lighting designer to match the fixture's output perfectly to the dimensions of the stage's backdrop.
Constructed for the demanding environment of the theater, the FC-1-CE is built with durability and heat management as priorities. The heavy-gauge steel housing is finished in a high-temperature black paint and is designed to withstand the intense thermal output of the 1500W T-20 lamp. The fixture incorporates a four-leaf color frame holder for inserting large sheets of theatrical color filter gel, which is the primary method for achieving the desired hue on the cyc. It is typically installed in rows—with fixtures placed on the floor (ground row) to light the lower portion of the cyc and on overhead pipes (top row) to light the upper portion—to create a uniform wash that eliminates a distinct horizon line.
As a workhorse of theatrical stage lighting, the Altman FC-1-CE provides lighting designers with a reliable and effective tool for one of the most fundamental stage lighting tasks: creating a flawless background. Its ability to produce a smooth, controllable wash makes it indispensable for dramatic scenes requiring a clean, neutral background as well as for vibrant musical numbers where the cyc is saturated with dynamic color. The fixture's robust construction ensures longevity in repertory and touring situations, making it a staple in the inventories of theaters, performing arts centers, and theatrical rental houses worldwide.
