Cooledge = Immersive Illumination
Immersive illumination is a subjective feeling of being surrounded by light in a way that feels comfortable and natural, like being outside. Immersive illumination is surprising: it delivers high levels of illumination but "feels like less" because we are used to experiencing localized higher levels of illumination created by traditional points and lines of light as inherently bright and in many cases somewhat uncomfortable.
Best in class (typical) 2 SDCM color uniformity
Creates a canopy of light that feels like being outdoors
Distributed lighting provides high levels of illumination without the visual discomfort of traditional lighting
Single CCT solutions are inherently immersive and Tunable White options expand that feeling to enable natural daytime or seasonal rhythms
Operational frequency of 3950 Hz is deep into the "safe zone" at all levels of light output
CRI >90
R-values comparable to specialty products Tunable White can be even better
Dimming down to 0.05% beats "dim-to-zero" (0.1%) offers from competitors
Exceeds requirements to qualify for LEED point and compliance with WELL v2 standard
Best in class <10% variance edge to edge
Optical and spectral characteristics of LEDs are altered when the light they emit passes through a diffuser. Cooledge provides LM-79 light quality data for the actual light output from fabric diffuser not just the LEDs, including:

Creating a vibrant, comfortable environment that enhances the experience of a space, whether for work, shopping, or leisure, is fundamentally based on delivering illumination that meets the specific needs of the user. To accomplish this requires more than just putting some LEDs behind a large diffuser and hoping there is enough light.
A complete solution requires an understanding of every aspect of lighting with documentation to support light level calculations, color rendering considerations, color uniformity, flicker and glare control, and dimming or tuning. That is why Cooledge luminous ceiling products not only deliver immersive illumination but have the proof to show it.
Vibrant AND Comfortable
Much as a diffuse sky delivers high levels of light by virtue of scale, the immersive illumination experience created with Cooledge luminous ceiling products similarly provides sufficient general area lighting without the visual discomfort of traditional lighting.
Immersive Illumination Encompasses Exceptional Color Rendering
To bring the feeling of the outdoors to interior spaces, it’s not good enough just to recreate the scale of nature. Our world is filled with colors that must be faithfully replicated by employing sources with exceptional color rendering properties. All Cooledge products have a Color Rendering Index (CRI) >90 with superior R9 values. Whether your goal is to highlight the merchandise in your shop or ensure your employees look as good as they feel, Cooledge luminous ceiling products deliver.
Cooledge publishes “Light Quality Metrics” documents for its luminous ceiling products. Unlike competitors who rely on LED supplier data which does not take into account the impact of diffuser materials, Cooledge color quality data is based on measurements of the light emitted from the fabric materials.

A key aspect in the understanding of the interaction between light and human physiology is the effect of flicker generated by electric sources of light. In the past, before the adoption of high frequency ballasts, you may have heard people complain about fluorescent lights, however, it is with the widespread adoption of LED sources that flicker has become an important design consideration.
Visible flicker occurs at relatively low frequencies (≤100 Hz), however, people may experience discomfort at frequencies that are considerably higher. Recent studies have indicated that the area of discomfort for some people may occur at even higher operating frequencies than previously thought – especially for LED sources using PWM dimming which has a very high modulation percentage.
Cooledge products incorporate dimming at a frequency (min. 3000hz) that is well within the recommended “safe zone” as currently defined by IEEE 1789-2015 (and included in WELL v2TM).
Cooledge products feature “deep dimming” down to 0.05% >> better than competitive products sold on the basis of premium dimming capability.
Immersive Illumination is Inherently Comfortable
Glare is another aspect of lighting that has been associated with poor user experiences ranging from mildly unpleasant to miserable. As opposed to the points and lines of traditional lighting, luminous ceilings are inherently low glare sources of illumination.
The calculation of glare is dependent upon the specific characteristics of a space and the position of the observer, however, some general recommendations provide guidance for determining the level of glare one might expect from lighting products.
The Unified Glare Rating (UGR) is one method used to analyze glare and its relationship to visual comfort. Good design practice targets a UGR value of <19 considered acceptable for general workspaces and <16 for more critical areas, while UGR values of 10-13 are considered to have a barely perceptible discomfort value.
