Swell hcb15

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

CutsheetExplore Swell



The Swell Series HCB15 is a linear recessed LED luminaire tailored for health-centric lighting installations. The 2” wide aperture is available with multiple optic options and constructed for installation in common grid ceilings or in hard walls and ceilings with flange and trimless variants. The HCB15 is Controls Capable, being offered with a variety of integrated control options.

The HCB15 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.
