The Light Controller is a tool that gives you fine control over your lights by clicking a point on a mesh object to reposition them.

To access the Light Controller Tool, select a Light object in your Scene hierarchy, and the icon will appear in the toolbar. The tool includes a Match Highlight option to make the specular highlight appear where you click.
You can adjust common light attributes with hotkeys for Brightness (Ctrl+LMB), Distance (Ctrl+RMB), and Spot Cone (Ctrl+MMB).
