H\u00f6gsta CRI v\u00e4rdet<\/h3>

En CRI p\u00e5 100 representerar det h\u00f6gsta m\u00f6jliga v\u00e4rdet. L\u00e4gre CRI-v\u00e4rden indikerar att vissa f\u00e4rger verkar onaturliga.<\/p>

Som exempel, gl\u00f6dlampor har en CRI \u00f6ver 95. M\u00e5nga kalla vita lysr\u00f6r har en CRI p\u00e5 62, men lysr\u00f6r som inneh\u00e5ller s\u00e4llsynta jordfosforer finns tillg\u00e4ngliga med CRI-v\u00e4rden 80 och h\u00f6gre.<\/p><\/div>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t
