“…The present study suggests that gamut area, or more precisely GAI, can be a useful, practical adjunct to the well-established CRI in ensuring both good color discrimination and satisfactory perceptions of object color ''vividness'' and ''naturalness.'' These data also reinforce the color rendering recommendations for NICUs 26 ; a light source providing a minimum CRI of 80 and a GAI between 80 and 100 will provide good color discrimination and make objects in the scene appear both ''vivid'' and ''natural,'' given sufficient illuminance is provided to the visual scene. Finally, it should be stressed that although this two-metric proposal appears to be both useful and practical, additional studies should be conducted to determine if these two metrics are ideal and are sufficient for ensuring good color rendering for architectural lighting in general and for niche applications in particular.…”

It was the best measure of color rendering, it was the worst measure of color rendering. Color rendering index (CRI) is the most common metric used by the lighting industry to represent the color rendering properties of electric light sources. CRI was intended to characterize how ''true'' or ''natural'' objects appeared when illuminated by a light source, but was never intended to, for example, represent how well object colors could be differentiated under a light source, another important aspect of color rendering. Data presented here demonstrate that CRI in conjunction with another measure of color rendering, gamut area index (GAI), is useful at predicting subjective judgments of how ''natural'' objects appear as well as how ''vivid'' objects appear, and how well one can discriminate between subtle differences in hue. Neither measure by itself, however, is sufficient for meeting all of the expectations of a light source for providing good color rendering under all viewing conditions. It remains for future research to determine if just two metrics are sufficient to assure good color rendering from a light source and whether these two metrics (CRI and GAI) are the best for such purpose. In the meantime, CRI and GAI should be used jointly in recommendations as practical, useful, and mutually reinforcing measures of color rendering. The data presented here also demonstrate that total irradiance is important for good color rendering.

“…39,40,[42][43][44] Hay evidencia de que, entre la semana 28 y la 32 de edad gestacional, la iluminación cíclica tiene consecuencias clínicas positivas en el neonato, pero hay pocos datos del efecto del ritmo circadiano en las funciones fisiológicas, en su crecimiento y en el desarrollo del sistema nervioso central. 40,42,[45][46][47][48][49][50] Aún no hay consenso sobre cómo introducir en la práctica ciclos circadianos con iluminación artificial ni hay un protocolo de implementación respecto a la duración de ciclos y niveles máximos/mínimos de iluminación.…”

“…39,40,[42][43][44] Evidence indicates that, between weeks 28 and 32 of gestation, cyclical lighting has positive clinical effects on the newborn infant, but there is little information on the effect of circadian rhythm on physiological functions, growth and development of the central nervous system. 40,42,[45][46][47][48][49][50] There is still no consensus on how to introduce circadian cycles with artificial lighting in practice neither is there an implementation protocol regarding cycle length and maximum/minimum lighting levels.…”

Achieving adequate lighting in neonatal intensive care units is a major challenge: in addition to the usual considerations of visual performance, cost, energy and aesthetics, there appear different biological needs of patients, health care providers and family members. Communicational aspects of light, its role as a facilitator of the visual function of doctors and nurses, and its effects on the newborn infant physiology and development were addressed in order to review the effects of light (natural and artificial) within neonatal care with a focus on development. The role of light in regulating the newborn infant circadian cycle in particular and the therapeutic use of light in general were also reviewed. For each aspect, practical recommendations were specified for a proper well-lit environment in neonatal intensive care units.
