Swell | hcb16

3” wide aperture recessed LED luminaire, Illuminated by BIOS®

CutsheetExplore Swell



The HCB16 is a linear recessed LED luminaire tailored for health-centric lighting installations. The 3” wide aperture is available with multiple lens options and constructed for installation in common grid ceilings or in hard walls and ceilings with flange and trimless variants.

The HCB16 fixture is embedded with BIOS SkyBlue® circadian solutions to produce the healthy “blue sky” light signal needed to stimulate human circadian biology. This specific light wavelength communicates directly with human biology through a non-visual photoreceptor to regulate circadian rhythms, providing healthier sleep patterns and ultimately, better health.
