 This property sets the strength or brightness of a Light.

 ### spatialScale
 {: #spatialScale}
 
-A single Quantity that defines a real-world scale factor for the coordinate units of a Canvas or Scene. For a Canvas, this defines the physical distance corresponding to the length of a single Canvas coordinate unit. A Canvas with a `width` of 5000 and a `spatialScale` with `quantityValue` 0.00008 represents a physical space 0.4 meters wide. For a Scene, this defines the physical distance corresponding to the XYZ coordinate units, or in other words, the physical distance length of a unit vector in the 3D coordinate space. The value of `unit` _MUST_ be a length unit. In this specification, the only length unit defined is `m`, i.e., meters. Unless other values are defined externally as an [extension][prezi30-ldce], the value of `unit` _SHOULD_ always be `m`.

 ### temporalScale
 {: #temporalScale}
 
-A single Quantity that defines a multiplier or scale factor for the `duration` property of a Container, indicating that one second in "Container time" represents some other real world duration. A Canvas with a `duration` of 450 seconds and a `temporalScale` with `quantityValue` 1000 represents a real-world duration of 450,000 seconds (5.2 days), for example a time-lapse video of a growing plant.
