What is a Fresnel light?


A Fresnel light is a focusable spotlight used in film, television and theater lighting. The light can be adjusted using a knob on the back of the light to create a narrow focused beam, or it can be adjusted to provide a wider beam of light.

It’s also used to light stages, since it produces an even light that’s soft at the edges. However, it does tend to project a soft shadow. Since a Fresnel light's edges are soft, it blends easily with other Fresnel lights.

The Fresnel light was named after French inventor Augustin Jean Fresnel, who designed the Fresnel lenses.
