Higher values will make indirect lighting brighter. A value of 1.0 represents physically accurate behavior, but higher values can be used to make indirect lighting propagate more visibly when using a low number of bounces. This can be used to speed up bake times by lowering the number of bounces then increasing the bounce indirect energy.
