A spotlight casts a focused beam of light like a flashlight, a follow spot in a theater, or a headlight. Unlike a targeted spotlight, a Free Spot has no target object. You can move and rotate the free spot to aim it in any direction.

To create a free spotlight:
The light is now part of the scene. It points away from you in the viewport you clicked.
You can adjust the light's direction with Move and Rotate or by using a Light viewport.
To change a viewport to a Light view:
3ds Max opens the Point-Of- View viewport label menu..
The Lights submenu shows the name of each spotlight or directional light in the scene.
The viewport now shows the light's point of view. You can use the Light Viewport Controls to adjust the light.
The default keyboard shortcut for switching to a Light viewport is $.
You aim a free spotlight by adjusting its orientation in a scene using Move and Rotate.
The free spotlight is useful when you want a spotlight to follow a path and either don't want to bother with linking a spotlight and target to a dummy object, or you need banking along the path.
When you create a Free Spot light, the Targeted parameter is adjustable on the General Parameters Rollout (Standard Lights) . This is a fixed value for target lights.
When on, 3ds Max sets a point to use as an invisible target about which the Free Spot can orbit. The spinner adjusts the distance to the target.
The target distance is animatable.
