Catchlight produces that beautiful reflection of the source of the key light on the eyes of the subject. This can add a lot of value to your portrait photos.

But what is so special about them? The shape. Ring lights are shaped like a ring and that shape allows the light to uniformly light a face, usually from a straight-on angle. The top-of-the-line ring lights such as the Spectrum Aurora 19” Gold Luxe II Ring light come with a colour temperature adjustment knob. A brilliant feature that allows you to match the colour of the light with the others in the studio. This is useful when you are working in a multi-light setup and or when you need to adjust the colour of your key-light with that of the ambient light in the room.

LED panel lights are a proper key light for portrait and other types of photography. That said, even ring lights can be used for purposes other than portrait photography. You can use a ring light for shooting product photography, for vlogging (as a continuous light) and so on.

If you are a portrait photographer, this light can serve dual purposes. First as the key light illuminating the face of the model. And second, where it is not the key light but the catchlight.
