Have you ever wondered what type of spotlight is commonly used in theater and stage lighting due to its ability to produce a wide range of beam angles? The answer lies in Fresnel spotlights.

By simply adjusting the focus knob, the user can control the size of the beam and create different lighting effects. This versatility makes Fresnel spotlights a popular choice in the entertainment industry where precise control over lighting is essential.

Whether you are illuminating a theater stage, film set, or photography studio, Fresnel spotlights offer a reliable and efficient lighting solution. Their ability to produce soft-edged beams and variable beam spreads make them indispensable tools for lighting professionals.
