Groups can be independently turned on and off with the Group On / Off button in the upper right of each group. To turn all lights off, click the sleep button at the top of the Light Control panel.  

## Use Case Examples

### Example 1: Standard Uniform Light

Many materials require even lighting across the subject. This is most often accomplished with two lights positioned equa-distant in mirrored position and angle to the object. By grouping these lights together, power adjustments made to one light will be made to the other to ensure uniformity.

### Example 2: Asymmetric Raking Light

A hard raking light occasionally needed to emphasize texture in an object. By grouping the copy lights together and placing the third raking light into a separate group, the raking lighting can be controlled separately from the copy light.
