Open-Face Light
Open-Face lights, as the name
implies, have no lens in front of the bulb and are therefore slightly birghter
per watt than a Fresnel. Open-Face fixtures use a double-ended lamp. They
have a round face and an adjustable reflector for flood / spot control and come
with barndoors and a scrim set. They are lightweight and durable.
Compared to a Fresnel, the flood / spot
mechanism is slightly different. The mechanism changes the globe's position
relative to the reflector. When the globe is close to the reflector, the
reflector sends out a wide beam; when the globe is pulled away from the
reflector, it reflects more rays in a narrower beam. Because light emanates
from both the bulb and the surface of the silver reflector, open-face lights
tend to spill light everywhere and this makes them suited as fill
light. Open-face lights are often bounced into a white surface such as
foamcore to create soft light.
Open-Face
lights are also known as RedHead Lights or Blondies and use halogen lamps with powers ranging from 50 watts to 2000 watts.
