To turn off all lighting group layers so that lighting group area boundaries and labels are not displayed on the drawing, go to
Ribbon: DM Electrical->Lighting Groups-> 
Turn Lighting Group Layers Off
Pulldown Menu: DM Electrical->Lighting Groups->Turn Lighting Group Layers Off
The layers that the lighting group area boundaries and labels are inserted on will be turned off.
By default, these layers are non-plotting and do not have to be turned off before plotting.
