lightfastness can be rapidly determined using a laboratory accelerated instrument, either a water-cooled xenon lamp device, such as an atlas fade-ometer or weather-ometer, or an air-cooled device, such as a xenotest 150 s or alpha. The xenon long arc, when properly filtered, simulates uv and visible solar radiation more closely than any other artificial light source. This assures that your test results are repeatable and reproducible. Xenon arc instruments are widely used by the textile, polymer, paint and automotive industries.
xenotest 220 220 is the result of more than 50 years of experience in design and manufacturing of xenon instruments for lightfastness testing of textiles.
