Read an IES detail page

Open any luminaire from the library and learn what every section of the detail page is telling you.

4 steps · 3 min read

The detail page is the source of truth for any luminaire in OpenLumen. Spending a couple of minutes here saves a lot of guesswork in the layout designer and report tools.

  1. Open a luminaire

    Click any row in the library list. You land on the luminaire's detail page with the Overview tab selected by default.

  2. Read the Overview

    The Overview pulls together the most-used metadata: Manufacturer, Catalog / model number, IES format version, plus the high-level Photometric data (total lumens, input watts, efficacy), physical Dimensions, and the Testing information from the IES file's header.

    Two badges next to the title tell you the file's status: Official for manufacturer-validated files and a Community badge for user uploads.

  3. Switch to the Photometric tab

    The Photometric tab is where the visualization lives: the polar candela distribution, linear plot, iso-candela contours, iso-illuminance grids, BUG rating, and zonal lumen summary. See the Photometric Analysis how-tos for what each of those means in practice.

  4. Inspect the raw file

    The File Content tab shows the raw text of the IES file — useful when you need to verify a specific candela value or the test conditions. Discussion lets you leave comments other library users can see, and Community lists who uploaded or verified the file.
