All dyed or printed material experience change in color when exposed to sunlight for a sufficiently long period because of the action of sunlight on pigments or dyes used in them.The severity of exposure in both time and intensity of daylight determines the extent of change in color. The color fastness is denoted by the number of the Light Fastness Standard Fabric that has changed color to the same extent as the test specimen. It is expressed as the numerical Rating for Light Fastness. MBTL Light Fastness Tester is designed to evaluate the color fastness to light.

Paramount MBTL Light Fastness Tester i9 ™ is designed to test color fastness of textile materials to sunlight. The main unit of the instrument is strictly as per standards with 500W MBTL (Mercury Blended Tungsten Lamp) fixed at bottom to create artificial sunlight and the topside in open for ventilation. Specially designed Sample holding device is provided to expose the samples. Temperature of the inside chamber is maintained by water circulation. Sample holding device has the provision to inject the humidity solution to maintain relative humidity of the sample. Digitally control re-settable hour meter is provided in the control panel to set exposure time.
