There are many different light fixtures used in photography:
- A Fresnel is identified by a glass lens with concentric circles on the front of the fixture. They are used as focusing lights since the lamp and reflector move together. They provide an even beam and some good shadow definitions.
- An open face is a light that doesn't use a lens. They may come with a safety glass or wire mesh. They provide a fairly wide beam and are ideal if you diffuse them through silk, a softbox or even by bouncing them off a reflective panel. They are generally lighter and cheaper than fresnels.
- A cyc light is designed to provide an even amount of light on cycloramas and backdrops. It can also be used as a multi-purpose flood or fill light for stage and studio.
- A par is a lightweight fixture that uses a parabolic aluminized reflector lamp. They are often used in stage and theatre productions.
- A wide angled floodlight is called a broadlight and is used to direct a large amount of light at a large area.
- A softlight is an indirect source where the light bounces off an internal reflector to form soft light and soft shadow edges.
- An ellipsoidal is also a spotlight which has a controlled narrow beam with a sharp edge and strong shadow definition.
These fixtures can cost up to several thousand dollars.
