Nissan finds a way to make sure cars' paint won’t fade with this 4,000-watt light

This is exactly what "Lit" really means. Have you ever admired a red automobile from the 90s? Especially one that savoured life on the outskirts of the south-west? If you have, you may have noticed that the sun rays ate capable of ravaging its paint. 

Automakers stepped up and strived to eliminate that fate and ended up putting in lots of time and effort into making sure the paint, interior trim pieces and plastic would be able to withstand the harmful UV rays in the long term.  

Nissan took a path that focused their testing on a mega-powerful light that resembles some kind of satellite coming from the future. Manufacturers employd the Xenon Weather-Ometer at their technical center in Farmington Hills, Michigan, to create a 4,000-watt xenon light bulb that is designed to emit the same wavelengths of light as the sun.

This wave length however, works in a controllable environment and shines for up to 24 hours in a day. This signifies that the XWO halves the time needed for a test; and if Nissan wanted to test survival of the paint when placed under real sunlight for a year, the XWO would be capable of complete the test in just six months.

Also, Engineers are able to put up to a 100 samples of material into the XWO at once which also helps in speeding up the testing process of new paints, plastics and other elements needed for a new car. The machine works by rotating the around the light bulb—recreating the movement of the sun over a car during the course of a day. Nissan engineers still manage to try out new colors and materials in real sunlight, but the XWO remains the best bet to accelerate the process.
