What type of light fixture is represented by a dashed circle in plans?

A dashed circle in plans represents a ceiling-mounted light fixture. This symbol is commonly used in architectural and electrical drawings to indicate where lighting will be installed on the ceiling. The dashed circle provides a clear visual distinction, signaling that the fixture is positioned above the floor level.

In contrast to other options, such as wall-mounted lights or portable lamps, which would have different symbols, the dashed circle effectively communicates the specific placement and type of lighting fixture intended for installation. It’s also important to note that outdoor lighting would typically have different representations altogether, as it generally requires additional considerations for placement and power source that are not depicted with a simple dashed circle. This standardized representation helps ensure that all parties involved in the project, from architects to electricians, understand the intended lighting layout without ambiguity.
