standard light source for print

 Function and Features :

 
1)  It is used to test the concolorous and different spectrum effects 

     to compare color defference of goods under different lights;

2) The artificial sunlight D65 recognized by the Commission International Eclairage (CIE)

     is regarded as the standard base lighting source;

3)  Illumination range of light source is 750 to 3200 Luxes;

    under different light sources;

7)  It can accurately record the service time of each group of luminous tubes.
     In general, the luminous tube should be replaced after the service of more than

     2000 hours for fear that the testing failure occurs due to the ageing of the luminous tube.

8)  Ultra-Violet Illuminant (UV) shall be equipped and used to test the articles with
