Which fixture utilizes a focusing barrel?

• A. Leko
• B. Fresnel
• C. PAR Can
• D. LED Panel

Answer: (A)

A focusing barrel is an adjustable cylindrical tube on ellipsoidal reflector spotlights that moves the lamp along the optical axis to tighten or soften the beam edge and to enable precise focusing and gobos. The fixture that uses this feature is the Leko, an ellipsoidal spotlight designed for sharp-edged beams and interchangeable gobos, lenses, and accessories. Fresnels use a fixed lens and produce a softer beam without a focusing barrel. PAR Can fixtures rely on a fixed reflector and lens options but don’t include a cylindrical focusing barrel. LED panels are flat light sources with no focusing barrel.
