ccsj-139	Musante, Fulvio; Rossi, Maurizio	An overview for colour rendering indices in Solid State Lighting	2014	6	.pdf	application/pdf	3624	155	50	The influence of the spectra of test samples on the calculated color rendering index is a long time open question: due to a small number of samples, lamps manufacturers are able to tailor the light sources spectral distribution to yield high CRI value, even if the visual impression of color rendering is considered poor[12][13]. Rea and Freyssinier-Nova suggest numerical recommendations about the value of GAI index: if the applications (for example retail) require high features for color rendering, the light source should have both Ra of between 80 and 100 and GAI between 80 and 100.[3][4] An important notice is that in GAI, the evaluation of the correlated color temperature of reference light source is fixed and independent from that of the source under test: this solution can involve distortions in the judgment of the light sources with low values of correlated color temperature that can still have excellent color quality including good color discrimination performance, despite the low value of the gamut area.	cache/ccsj-139.pdf	txt/ccsj-139.txt
