Incorporate Luminaire Objects
A luminaire object is a helper object that assembles a set of objects into a light
fixture.
A luminaire object groups and manages the components of a light as a whole.
Light fixtures can be represented by embedding photometric lights in blocks

into a light fixture.
Tool palettes of photometric lights are available to provide easy access to create
a luminaire object. Luminaire objects are offered through plug-ins.
