# Light

### Description

A Light [OverNode](/over-sdk-manual/over-visual-scripting-legacy/visual-scripting-essentials/overnode.md) is used to handle lights in the Scene, by interacting with the Unity3D [Light](https://docs.unity3d.com/ScriptReference/Light.html) Component.

#### Light Exposer

This [OverNode](/over-sdk-manual/over-visual-scripting-legacy/visual-scripting-essentials/overnode.md) is used to expose certain parameters and attributes of a given input Unity 3D [Light](https://docs.unity3d.com/ScriptReference/Light.html) Component, which are:

<table><thead><tr><th>Name</th><th width="204.3279424240331">Type</th><th width="340.1572968009442">Description</th></tr></thead><tbody><tr><td>Ref</td><td><a href="https://docs.unity3d.com/ScriptReference/Light.html">Light</a></td><td>A reference of the input Unity3D Light Component</td></tr><tr><td>Intensity</td><td>Float</td><td>Value representing the light intensity</td></tr><tr><td>Color</td><td>Color</td><td>Color of the light</td></tr><tr><td>Range</td><td>Float</td><td>Range of the light</td></tr></tbody></table>

#### Set Intensity

This node is used to modify an existing Light Component, by setting its Light Intensity.

The intensity of the light is multiplied by the Light colour.

The value can be between 0 and 8. This allows you to create brighter lights.

This Flow [OverNode](/over-sdk-manual/over-visual-scripting-legacy/visual-scripting-essentials/overnode.md) accepts the following input data:

<table><thead><tr><th width="205.7659040188865">Name</th><th width="196.3279424240331">Type</th><th width="340.1572968009442">Description</th></tr></thead><tbody><tr><td>Light</td><td><a href="https://docs.unity3d.com/ScriptReference/Light.html">Light</a></td><td>A reference of the input Unity3D Light Component</td></tr><tr><td>Intensity</td><td>Float</td><td>Intensity value (between 0 and 8)</td></tr></tbody></table>

and produces the following output data:

<table><thead><tr><th width="186.7659040188865">Name</th><th width="207.3279424240331">Type</th><th width="340.1572968009442">Description</th></tr></thead><tbody><tr><td>Output</td><td><a href="https://docs.unity3d.com/ScriptReference/Light.html">Light</a></td><td>A reference of the modified Unity3D Light Component</td></tr></tbody></table>

#### Set Color

This [OverNode](/over-sdk-manual/over-visual-scripting-legacy/visual-scripting-essentials/overnode.md) is used to modify an existing Light Component, by setting its Light Color.

The Color of the light is multiplied by the Light intensity.

This Flow [OverNode](/over-sdk-manual/over-visual-scripting-legacy/visual-scripting-essentials/overnode.md) accepts the following input data:
