# Signify luminaire Revit and photometric-file guide

A luminaire is a complete light fitting. Its BIM/Revit model supports building coordination, while IES or LDT photometric data describes how the selected lighting configuration distributes light.

Select the product and configuration. IES/LDT photometric data describes lighting performance and is not a CAD model; BIM availability varies by family.
Official-source discovery only. Confirm the selected regional product, installation configuration and documentation with the manufacturer.
Choose the exact luminaire code, optic and mounting arrangement on the official product route. Obtain the available BIM model, dimensional document and photometric file for that selection. Keep these deliverables distinct: a 3D fitting model does not establish the room’s calculated lighting performance.


## In plain English

### What is this Signify resource?

A luminaire is a complete light fitting. Its BIM/Revit model supports building coordination, while IES or LDT photometric data describes how the selected lighting configuration distributes light.

### A simple example

A designer can place a fitting in a ceiling model and use a separate matching photometric file for a lighting calculation.

### What the drawings help you do

Choose the exact luminaire code, optic and mounting arrangement on the official product route. Obtain the available BIM model, dimensional document and photometric file for that selection. Keep these deliverables distinct: a 3D fitting model does not establish the room’s calculated lighting performance.

### Before using this reference

- Provide complete luminaire and optic/configuration codes.
- Specify the intended mounting and model format.
- Request matching photometric data and installation documents.

### Can an IES or LDT file replace a Revit model?

They serve different purposes. IES/LDT data supports lighting-distribution calculations; a Revit resource supports building-model coordination. Obtain both where the project needs both.

### Terms

- Geometry: The physical shape represented by the model or drawing.
- Configuration: The exact equipment version and options selected for the installation.
- Revision: The recorded version of the file or document.

## Which file should I choose?

Choose the exact luminaire code, optic and mounting arrangement on the official product route. Obtain the available BIM model, dimensional document and photometric file for that selection. Keep these deliverables distinct: a 3D fitting model does not establish the room’s calculated lighting performance.
