You can access luminance properties via the Properties window of an object (see Object Properties), or by using the Luminances Palette (see Race98521). Palette

Note: If you are specifying luminance for the overall drawing, use the Render Scene Luminance. Drawing luminance can be applied either to the WCS (World Coordinate System) or UCS (User Coordinate System). See WCS and UCS.

Category: Three categories are provided for you, but you can create new ones.
Single: Defines only one light type. See Ring25216.
Complex: Defines two or more lights. See Ring20837. Flo Anchor
Floresc Architec AV: A set of light types representing realistic lights, based on .ies files from Lithonia Lighting. These files are stored in the Luminance\Photometric\ies folder. *
Luminance: This field depends on the category. See the relevant section for details.
Edit Luminance: Opens the Luminance Editor. See Editing Luminances.Loa Anchor
Load to render Luminance only: Check if you want to view only the object lights, and not the object itself.

Light Types
Anchor
Ambient: Illuminates all surfaces equally, regardless of orientation.Ar Anchor
Area: Simulates a luminous surface.Are Anchor
Area Goniometric: Combines area and goniometric shaders.Ar Anchor 76 76 , but models only sky light that passes through portals, such as a window or door. *Dis Anchor
Distant: Light that is constant and parallel (non-conical).Ey Anchor
Eye: A light source located at the view point.Go Anchor
Goniometric: Directional light, whose direction is specified by an .ies file (a text-based file). This luminance is useful for creating lighting based on manufacturers' lighting data, such as room lights, building lights, and street lights. *P Anchor
Point: Light from a selected position.Pr Anchor
Projector: Projects a graphic image onto a solid object. An image file with full path must be specified.Si Anchor
Simple Environment: A light shader that uses an environment map to light a scene.Sim Anchor
Simple Sky: A simplified sky shader which models the illumination from a uniformly bright, single-color, hemispherical dome representing the sky.Sk Anchor
Sky: An area light that simulates sky light, providing soft and natural shadows. This light is modeled as a hemisphere of infinite radius, positioned above the center of the model.S Anchor
Spot: Provides directional light that is constrained to a cone.Su Anchor
Sun: Projects a spot light from a very distant point, to simulates outdoor sunlight. You can combine Sun and Sky lights for a realistic rendering effect.
