The Light Selection Display shows the last light or decoration type selected. All lights and decorations can be assigned a unit price. The cost will be displayed on the "Light Count" report located in the "Reports" menu. A Controller is a group of 16 channels. Channels contain lights and decorations. Lights and decorations are assigned to the displayed controller and channel when they are added to a project. A controller is similar to a power strip. A channel is similar to a unique plug in a power strip.
Loop channels allow you to automatically assign different channels to each bulb as you lay down a strand of bulbs. The resulting effect is similar to putting down three strands of lights at once. This saves time when building a chase sequence for example.
