High-CRI LED lighting

High-CRI LED lighting is a <a href="/facts/Light-emitting_diode/gE8x4MDb">light-emitting diode</a> (LED) lighting source that offers a high <a href="/facts/Color_rendering_index/aaIJkcRn">color rendering index</a> (CRI).
CRI is a quantitative measure of a light's ability to reproduce the colors of objects faithfully in comparison with an ideal or natural light source. In general terms, CRI is a measure of a light source's ability to show object colors "realistically" or "naturally" compared to a familiar reference source, either incandescent light or <a href="/facts/Sunlight/WPkJRC7s">sunlight</a>.
Efficiently achieving an acceptable CRI has been the most difficult metric for more modern <a href="/facts/Electric_light/v3fb5WBp">light bulbs</a> attempting to replace older <a href="/facts/Incandescent_light_bulb/31frjg0A">incandescent bulbs</a>. It is therefore frequently ignored in marketing (the CRI value only occasionally appears on product packaging). Light bulbs with a high CRI can be acceptable replacements for incandescent bulbs. Most <a href="/facts/LED_lamp/kMsxpkk9">LED lamps</a> do not have a CRI above 90. For example, the top bulbs listed in the 2016 Consumer Review have a CRI of 80.
In 2008, the <a href="/facts/United_States_Department_of_Energy/PRp6Cz8g">U.S. Department of Energy</a> created the <a href="/facts/L_Prize/CJXkQKql">L Prize</a> to find an incandescent light bulb replacement that met efficiency metrics and had a CRI above 90. On August 3, 2011, <a href="/facts/Philips/Xp4uczGg">Philips</a> was declared as the first winner of the L Prize.
