About this Photometric File
This page presents the IES photometric distribution for the AT19-18W9F1OSJ6 from LedsC4, a LEDS C4 brand. This product line is published as 10 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.
