Light Fastness Tester for Fabric Appilcation

This Light Fastness Testing Machine is suitable for conducting tests on the lightfastness of colors, resistance to environmental factors, colorfastness in the presence of light and perspiration, as well as the resistance to light-induced aging. It can be used for testing various materials such as textiles, paints, dyes, coatings, rubber, plastics, wooden floors, paper, and more. Additionally, it is equipped with features that allow it to withstand exposure to rain, revolutions, and mist spraying, thus ensuring reliable results even under challenging climatic conditions.


Light Fastness Tester for Fabric Feature


  1. 1. Rated 2500W long-arc xenon lamp technology adopted to real simulate sunlight spectrum
  2. High transmittance of filter combinations and use 95% of the transmittance filters and filter cartridges. With Low power consumption but achieve the same irradiation light requirements. To make the machine is more energy saving and environment friendly.
  3. 2. Digital setting of light intensity , real-time monitoring, automatic adjustment,to meet the different standards for testing the stability of light source 
  4. 3. Test and radio transmission are powered by using light conversion technology, no additional power supply is required.
  5. 4. The sample is tested with black plate thermometer(BPT),black plate standard thermometer(BST), irradiance detector at the same position(in equidistance) to really indicate measuring state of the sample,the tested data is transmitted synchronously by using technolody of radio frequency.
  6. 5. With industrial temperature control (refrigeration) system for smoothly and fast adjusting temperature in test chamber.
  7. 6. With several modes of operation (rain, alternating light and dark, revolution), can simulate the real climate state.
  8. 7. Individual timing of each sample clamp may enable different sample test in a same tester and facilitate test monitor and reduce operation cost.
  9. 8. 10.4 inch color touching screen display control and various test monitoring modules (animation,digit,chart)make operation easy,visual and clear.

9. One test can run for 1000 hour continuously with quality guarantee.
