### Remarks

Indicates the distance, in meters, where a surface should receive the amount of light equivalent to the provided number of [LightUnit.Lux](/engine/6000.6/script-reference/unityengine/rendering/lightunit/lux.md). Only relevant for lights with range attenuation & intensity measured in [LightUnit.Lux](/engine/6000.6/script-reference/unityengine/rendering/lightunit/lux.md). Only Scriptable Render Pipelines use this property; the built-in renderer does not support it.
