This page presents the IES photometric distribution for the Commercial Grade / H43T — H43-438_75R30SP from HALO, a Cooper Lighting Solutions 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.
