When space is at a premium, Concentric Rings are often the designer's first choice for beam control. Concentric Rings deliver 45° cutoff for full control of stray beams and spill, like a full Top Hat, but they do it in a shorter device. Concentric Rings also provide a "Svoboda-like" style when used on lighting fixtures that are in view of the audience, and present a deeply theatrical feel. Designed for the fixtures below, and should work on other fixtures* which use the same media frame size. Use with caution on LED fixtures without a fully homogenized beam, color shifts may occur.

Offers full control of stray beams and spill
