Diamond grading lamp FDL-12


Illumination is very important in the color grading of diamonds. The use of a uniform light source can eliminate the effect of different light sources on the color. The diamond grading lamp produced by our company requires the light source to have the characteristics of no ultraviolet light, uniform light energy distribution, low heat generation, soft light, and color temperature of 5500K-7200K. It meets the requirements of the diamond grading standard light source, and to a certain extent can ensure the accuracy and comparability of the diamond grading results. It is an ideal lighting fixture for diamond grading.
