Defining the Initial Intensity

When defining a lighting fixture, you can specify the initial intensity of its light source. The initial intensity is a measure of how much light is produced by the light source in ideal conditions. (The actual light emitted by a light source may be reduced by light loss factors. See Light Loss Factor Parameters.)

You can define the initial intensity of a light source in a lighting fixture family file (as follows). In a project, you can change the initial intensity of an individual lighting fixture. (See Changing the Initial Intensity of a Light Source.)

To define the initial intensity of a lighting fixture family

1. Open the lighting fixture family.
2. Click Create tabProperties panel (Family Types).
3. For Name, select the family type to modify.
4. Scroll down the list to locate the Initial Intensity parameter, and click in its Value column.
5. In the Initial Intensity dialog, specify values for the parameters.

   See Initial Intensity Parameters.

6. Click OK.

   The Family Types dialog displays the new Initial Intensity value.

7. Click OK.
8. Save changes to the lighting fixture family.
