Soft Light

Soft-Lights are designed to
produce soft light with less-defined shadows. Light from the long tubular
globes is directed into a white concave reflector. Because it is indirect,
bounced off a diffused white surface, and exits through a relatively large
aperture, the resulting light is soft and has a wide, even uncontrolled spread.
Soft-lights are commonly used for fill and general room ambiance.
Because soft-lights use indirect light, they produce
less light per watt than Fresnels and even less light than Open-Face lights.
Most soft-lights have multiple globes, each switched individually, making it
easy to increase or reduce the light's intensity. Generally, they don't use
scrims, but can be improvised by inserting a baby scrim between the base and
the white reflector surface.
