Fresnel studio lights are lighting fixtures commonly used in theatre, film, and studio productions. They feature a distinctive lens design with concentric circles, allowing for adjustable beam angles and focus. These lights provide a soft-edged beam with variable spread, making them versatile for different lighting applications. Equipped with tungsten or LED light sources, they offer warm and controllable illumination. Fresnel lights are used for key lighting, fill lighting, and general wash lighting in stage and studio settings. With adjustable barn doors or flags, the light beam can be shaped and controlled. Mounted on stands or grids, they are easily positioned and focused. Their versatility, controllability, and ability to produce soft and even lighting make Fresnel studio lights popular in professional productions, including theatre, film, television, and photography.
