# Sandbox.LightModulator.Brightness

```csharp
float Brightness { get; set; }
```

Linear brightness multiplier after contrast. One preserves brightness; values above one boost light.
Alpha is unaffected. This is an artistic light multiplier, not physical light focusing.

Declared in [Sandbox.LightModulator](/api/Sandbox.LightModulator).
Assembly: `Sandbox.Engine`.
