2” wide direct/indirect LED luminaire, Illuminated by BIOS®

CutsheetExplore Swell



The Swell Series HCB12 is a linear LED luminaire tailored for health-centric lighting installations. The 2” wide by 3-1/2” high extruded aluminum housing is offered for wall or cable suspended mounting and variety of optic options. The HCB12 is Controls Capable, being offered with a variety of integrated control options.

The HBC12 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.
