Which fixture uses a spherical reflector?

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

Answer: (A)

In lighting fixtures, the shape of the reflector determines how the light is directed and how soft or sharp the beam will be. A spherical reflector behind the lamp is a hallmark of the Fresnel fixture. That rounded reflector redirects light toward the front lens and, together with the Fresnel lens, creates a soft, even wash with smooth falloff. The other options use different reflector shapes or approaches: PAR fixtures use a parabolic reflector to shape the beam differently, ellipsoidal/LEKO fixtures use an ellipsoidal reflector for precise, hard-edged beams, and LED panels rely on LEDs and diffusers rather than a spherical reflector.
