What document provides information about the types of lights used?

The fixture schedule is the document that provides detailed information about the types of lights used in a project. It typically includes specifics such as the manufacturer, model number, wattage, color temperature, and any other relevant characteristics of each lighting fixture. This schedule allows electrical contractors and other professionals to understand what types of lights will be installed, ensuring that the appropriate fixtures are selected and ordered in accordance with the design intent.

A lighting plan, while it illustrates the layout and placement of light fixtures, does not provide the specific details about each fixture. The electrical plan outlines the overall electrical system and wiring but does not focus specifically on the types of lights. A specification sheet provides detailed information about a specific product but is generally used for a single item rather than an entire schedule of fixtures.

Thus, the fixture schedule is essential for coordinating the lighting elements in a project, making it the most accurate answer.
