When placing standing lights, or upwards facing recessed lights you can only do this using a Floor Plan view. You can use the Shaded or Realistic modes in the Revit viewport to see how the light hits a wall or other surfaces in Revit itself. However, when placing interior light fixtures in a project in Revit, although it is possible to place a light object in a 3D view, it is normally easier and better to perform this operation using a Floor or Ceiling Plan view which can be opened from within the Revit Project Browser. You can place lights in a Revit 3D view, as well as one of Revit’s Plan views in order to plan the appropriate spacing, angle, and setback of lighting fixtures in the building model. Lighting fixtures in Revit are hosted components meaning they must be placed on a host component (wall, ceiling, table), either in an internal or external location within the project.
