Rectangle – Sets the shape to a planar rectangle.Įllipse – Sets the shape to a planar ellipse. Shape – Specifies the structure of the light object. The intensity of the light depends on its size. Radiance (W/m^2/sr) – Visible light surface power measured in watts per square meter per steradian. A typical 100W light bulb only emits between 2 and 3 watts as visible light. This is not the same as the electric power consumed by a light bulb. The intensity of the light does not depend on its size. Radiant Power (W) – Total emitted visible light power measured in watts. ![]() Luminance (lm/m^2/sr) – Visible light surface power measured in lumens per square meter per steradian. A typical 100W incandescent light bulb emits about 1500 lumens of light. The intensity of the light will not depend on its size. Luminous Power (Lumens) – Total emitted visible light power measured in lumens. The light surface will appear with the given color in the final image when seen directly by the camera. ![]() The light automatically takes the scene units scale into consideration to produce correct result.ĭefault (Scalar) – The color and multiplier directly determine the visible color of the light without any conversion. Using correct units is essential when working with the physical camera exposure. Units – Specifies the light unit of measurement. Intensity – Specifies the strength of the light.
