Chapter 25 Luminaire Schedules and Cut Sheets

The most important support documents that accompany a lighting plan are the luminaire schedule and cut sheets that illustrate exactly what lighting equipment is required to bring the lighting plan to life. All of the deliverable documents must be accurate and error free, but this holds especially true for the schedule and cut sheets, as they will inform the ordering of lighting products. On complex projects, architects and engineers create specification documents that articulate the specific nuances of every product and material that is necessary for the construction of the project. The luminaire schedule and cut sheets are the closest a lighting designer gets to true “specification”. As such, these documents that must list products accurately and completely. The luminaire schedule is the document that the electrical contractor will use to price, order and install the lighting equipment. This means that a slight error in catalog number or description can affect the budgeting, delivery and installation of every instance of a particular luminaire type. The two secrets to a thorough luminaire schedule are to get started early (as discussed in Chapter 24), and to check and re-check the schedule and cut sheets for errors. By now, readers have seen enough manufacturers’ literature to know that the catalog numbers for lighting products can become rather lengthy and complex. A simple typo can cause a product to be delivered in the wrong size, the wrong color, or not at all.
THE LUMINAIRE SCHEDULE
The sample luminaire schedule shown in Figure 25.1 includes most of the pertinent information one would need to provide for a project. Each category has critical information that must be presented in a manner that makes things clear and obvious. The contents of the various categories of information are discussed here.
Heading
The first piece of information that should go on a luminaire schedule is the name of the project and the date the schedule was created. With so many projects going on at once, and so many changes being made to luminaire selections, this labeling ensures that those involved with the project are referring to the correct document. The heading should also include the name of the firm or individual preparing the document so that those involved in the project know whom to contact with questions.
