What is a Parabolic Reflector?

  In lighting terms, a reflector is a device that controls light distribution by redirecting a lamp’s light in a specific direction. A parabolic reflector is typically used to redirect light given off by an HID lamp.

Why is it Called a Parabolic Reflector?

  The term “parabolic” refers to the shape of the reflector. That is to say, this particular reflector takes the shape of a circular paraboloid. A commonplace example of a parabolic reflector would be the reflector you see encircling the bulb of a flashlight.
