About this Photometric File

This page presents the IES photometric distribution for the Holophane SOMERSET from Holophane, a Acuity Brands brand.

You can use this fixture in CircadianLab to design lighting layouts and calculate melanopic equivalent lux (EML), illuminance in lux or foot-candles, and UGR glare ratings — all in your browser, free, with no signup required.

Note on photometric plots: All plots on this page treat the luminaire as a point source emitting from its photometric center, which is the standard convention for IES LM-63 data.

Disclaimer: Innerscene does not manufacture, sell, or distribute the Holophane SOMERSET or any other Holophane products. This page is provided for informational and lighting-design purposes only, using publicly available photometric data. For product inquiries, pricing, or availability, please contact Holophane (Acuity Brands) directly.
