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 fixetures use a double-ended lamp . They
have a round face and an adjustable reflector for flood / spot control and come
with barn doors and a scrim set. They are lightweight and durable .
Compared to a Fresnel, the flood / spot
mechanism is slightly different . The mechanism change 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 of rays in a narrower beam. Because light emanates
from both the bulb and the surface of the silve reflector, open face lights
tend to spill light everywhere and this make them good to be use as a fill
light . Open-face lights are offen bounced into a white surface such as
foamcore to create soft light.
Open-Face
lights are also known as “RedHead Lights” or “Blondie” and use halogen lamps with powers form 50 watts to 2000 watts .
