FEATURES

Dual-reflectance technology

Circadian Sky expertly replicates the characteristics of a double-pane window, employing advanced reflective technology to foster a heightened sense of depth and realism.

Through the integration of a highly reflective light guide panel, a secondary reflection is induced, mimicking the distinctive double reflections found in traditional windows and enhancing the spatial perception of your environment.

DUOGLASS™

Innerscene proprietary multilayering of our ATMOS PLATFORMTM and ANSI-rated tough tempered glass, when combined with an integral deep regress. our Circadian Sky fixture is not only highly durable but also looks incredibly realistic when compared to a traditional double-glazed skylight.

ATMOS PLATFORMTM 4+ CHIP COLOR SYSTEM

The ATMOS Platform in Circadian Sky features a four-chip LED system designed for high Color Rendering Index (CRI) and precise chromaticity control. This system uses four different LED chips/ colors to achieve accurate CIE xy coordinates, closely following the daylight locus and blackbody curves over a broad range from 2,200K to 40,000K.

In comparison, traditional two-chip tunable white systems incorporate only two types of white LEDs. These systems provide limited adjustable color temperature but lack the comprehensive CRI and exact CIE xy point control offered by the four-chip configuration in the ATMOS Platform. This design enables a lighting experience that more accurately replicates the variability, color, and spectrum of natural daylight.

COLOR TEMPERATURE RANGE

Colors of white light are referred to as CCT in Kelvin, lower numbers are warmer tones, higher numbers are cooler or bluer tones. There is no upper limit of Kelvin. However, in Non-Innerscene products may have blue skies with low color rendition leading to color casts which can be unpleasant.


40,000K : Innerscene's deepest blue sky
20,000K : Blue Sky
6,500K : Pure White - highest color temperature for commercial lighting
3,500-4,000K : Commercial White
2,700-3,000K : Warm White - comparable to bright incandescent lamps
2,200K : Warmest hues of sunrise or sunset
