When checking the placement of lighting fixtures in a T-bar ceiling, what should one refer to?

Reflected ceiling drawings are specifically designed to show the ceiling layout as it will appear from below, including the placement of lighting fixtures, air diffusers, and other architectural elements. This drawing provides a clear visualization of how the ceiling will look and helps to ensure that the fixtures are installed in alignment with design intentions.

In contrast, architectural drawings usually provide a more general overview of the building's layout and features. While they might include some information on lighting, they are not tailored specifically for the ceiling's presentation. Electrical layouts focus more on wiring and power distribution rather than the aesthetic or spatial placement of fixtures. Blueprints can also be more general and may not give the specific details needed for ceiling fixture placement. Therefore, the reflected ceiling drawing is the most relevant reference for accurately positioning lighting fixtures in a T-bar ceiling.
