BIOS SkyBlue™ Lighting Technology.

Healthy lighting at last.

BIOS with SkyBlue™ Technology is driven by scientific findings that were first developed at NASA and engineered for astronauts at the International Space. BIOS circadian-friendly white lights features high efficacy, high CRI and accurately calibrated color points.

SkyBlue contributes toward meeting the circadian lighting portions of the WELL Building Standard and is being integrated into light fixtures of leading commercial lighting manufacturers. Just look for the “Illuminated by BIOS” icon or ask your specifier for BIOS LED lighting with SkyBlue Technology.

Light is the strongest time cue for the circadian system.

Light signals the body clock whether it is night or day and therefore if it should be awake, alert, restful or regenerative. Photobiologists discovered a light-sensitive protein in the eye’s retina called melanopsin that detects intensity or changing levels of light. This photoreceptor projects to a different, non-visual part of the brain where our circadian clock is located. So when sunlight gets brighter in the morning, melanopsin becomes very active and triggers the brain’s body clock, or suprachiasmatic nucleus, to shift into an active day pattern.

All blue light is NOT created equal.

A lot of claims have been made on blue light.  Some say it’s good and some say its bad.  In fact there are two regions of blue light that are different; a good blue light regions and a bad blue light region.  The good blue light, which aligns with novel circadian photoreceptor melanopsin, has a peak near 490nm and appears more like a sky blue color, while the bad blue has a peak region from 420nm to 450nm is defined by the Illuminating Engineering Society as Blue Light Hazard, and appears more as a royal blue color.

Legacy LED is hitting the wrong curve.

Current LED Technology exacerbates the problems caused by electric lighting. Their spectrum actually has a trough in the good blue region (melanopsin) with peaks in the bad blue (blue light hazard).  While colors may appear close to daylight, the spectrum is drastically different.

What is Blue-light Hazard?

Blue-light Hazard is defined as the potential for a photochemical induced retinal injury resulting from radiation exposure.  While acute photochemical injury is rare, oxidative stress on your eye is common and leads to cellular aging.

BIOS SkyBlue™. A true blue light special.

BIOS with SkyBlue™ Technology infuses blue sky spectrum into LED light to help bring back circadian rhythms. BIOS SkyBlue™ LED Technology provides the maximum good blue (melanopic flux) with minimal bad blue (blue light hazard). It’s the CORRECT spectrum on the PROPER curve.

BIOS circadian-friendly white light. The right color, curves and rhythms.

SPD of BIOS verses Melanopsin and Blue Light Hazard

BIOS with SkyBlue™ Technology is driven by scientific findings that were first developed at NASA and engineered for astronauts at the International Space Station who depend completely on electric light. BIOS circadian-friendly white lights feature:

  • High efficacy
  • 85-90 CRI (CCT dependent)
  • Significantly higher melanopic flux than standard white light*
  • Factory calibrated color points
  • 5-year warranty

*At same color temperature and light levels (lux)

Equivalent Melanopic Lux  (EML) Ratio and Color Temperature

Color temperature shifts change melanopic content. Equivalent Melanopic Lux (EML) is a ratio to convert standard lux into melanopic equivalent. Currently, the WELL Building Standard targets 250 Melanopic Lux. The charts below compare EML ratio of lighting technology, daylight and BIOS SkyBlue.
