In the context of The Night Watch, discuss the New LED illumination of the History.
On 26 October 2011, the Rijksmuseum unveiled new, sustainable LED lighting for The Night Watch.  With new technology, it is the first time LED lighting has been able to render the fine nuances of the painting's complex color palette.The new illumination uses LED lights with a color temperature of 3,200 kelvin, similar to warm-white light sources such as tungsten halogen. It has a color rendering index of over 90, which makes it suitable for the illumination of artifacts such as The Night Watch. Using the new LED lighting, the museum saves 80% on energy and offers the painting a safer environment because of the absence of UV radiation and heat.
