1. From the Architecture tab in the ribbon, click the Component tool, and from the Type
Selector, choose the Downlight - Recessed Can family that has been preloaded from the
default Revit library. You can use the 6” Incandescent - 120V type.
2. Place fixtures in the ceiling plan along the lower and right walls as shown in Figure 11.70.
The exact dimensions aren’t important—just get the idea right.

Place light fixtures in ceiling

This light family doesn’t have a lens, so you don’t have to worry about the light source being
obscured. Before you start to render these artificial lights, we need to explain the process and
technique of using light groups.

Certification Manipulating Light Groups
Objective
There are times when you’ll want to isolate the lights that are being calculated and rendered in
a particular view. You might want to test the lighting that will result from having certain lights
on and others off, just as in a real space. Revit software allows you to create light groups for
this purpose. Doing so saves you a lot of time compared to turning individual lights off and on
manually.
By default, whenever you place lights in your project, they’re not placed in any group. They’re
“unassigned,” just like the lights shown in Figure 11.71. This dialog box can be found by clicking
the Render tool from the view control bar and then selecting the Artificial Lights button from
the Rendering dialog box. Here you can assign and create all kinds of light groups.
