Which fixture is defined by having an ellipsoidal reflector?

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

Answer: (A)

The defining feature here is a beam that is tightly controlled and sharply edged, produced by an ellipsoidal reflector that redirects light from the source into a precise, shapeable beam. The fixture designed around that ellipsoidal reflector—often referred to by its common name for this design—uses this reflector with a focusing lens and internal shutters to shape and trim the beam, giving you crisp edges and adjustable focus. That combination of an ellipsoidal reflector with precise beam control is what makes this fixture distinct. In practice, this means you can set a very clean spot, close to a hard edge, and adjust it with shutters and iris for exact patterns. By contrast, a Fresnel uses a stepped lens that softens the beam for a washier, more diffuse light; a PAR relies on a parabolic reflector with a simple lens for a strong, often more uniform beam but without the same edge control; and an LED panel uses multiple LEDs with diffusers, not an ellipsoidal reflector, so it doesn’t deliver the same crisp, shapeable beam.
