Which lighting fixture has a sharp edge and can project a pattern (gobo)?

• A. Par cans
• B. Ellipsoidal
• C. Fresnel
• D. Follow spot

Answer: (B)

The key idea is that a fixture designed to produce a crisp, sharply cut beam with the ability to project a pattern uses a gobo in a dedicated slot and a lens arrangement that sharpens the edge. An ellipsoidal reflector spotlight accomplishes this by routing light through a long throw lens with an adjustable gate and shutters. The shutters crop the beam for a clean, defined edge, and the gobo slot lets you slide in a pattern to be projected onto the stage. The focus and optional iris and zoom allow you to tighten or widen the beam while keeping the pattern sharp, making it ideal for logos, textures, or shapes. Par cans, by contrast, typically produce broader, softer edges without built-in shutters or a gobo slot, so their shapes aren’t crisp or pattern-driven. Fresnels have soft edges due to their lens design, which scatters the beam rather than producing a hard cutoff. Follow spots are great for tracking performers and producing a strong beam, but they don’t inherently provide pattern projection with gobos.
