Area lights are rectangular light sources that produce light from the whole area of the rectangle. Area lights produce soft shadows and the larger the light, the softer the shadow. The downside is that they do take longer to render than point and spotlights.

When you place an Area Light in Shaderlight it is marked by a rectangular area light component. There is a half yellow dot in the center of the component which indicates which side of the rectangle emits light. The white rectangle indicates the extent of the light source. You can select, move and rotate the component in your scene to place the source of the light, but the component itself won't appear in your Shaderlight image.

Area Light Properties

 

You can change the intensity and color of the area light.

 

Intensity – The intensity of the area light is set in candela and the default value of 125 candela is roughly the light emitted by a 100 watt tungsten light bulb. (One candela is roughly the amount of light emitted in any given direction by a "standard" candle).

 

Color – The color of the light can be changed using the color sliders (either HSB or RGB) and can be seen in the color swatch at the top left of the window.
