About this Photometric File

This page presents the IES photometric distribution for the LCR810RD9FSE020-12W-2700K_1085lumen from HALO, a Cooper Lighting Solutions brand. This product line is published as 6 variants — typically different CCT and CRI combinations of the same luminaire optic. Use the variant selector above to switch between them.

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 LCR810RD9FSE020-12W-2700K_1085lumen or any other HALO products. This page is provided for informational and lighting-design purposes only, using publicly available photometric data.
