Regarding the issue of product quality of China’s LED manufacturer Ledman, customers jointly claimed that they made the third-party authentication, but they didn’t show it at that time, while Ledman replied that the company has never seen the third-party authentication. Now, the disputable third-party authentication has been delivered.

Gtek entrusted the National Semiconductor Device Quality Supervision and Inspection Center with the inspection on the sample products of LS-DTEP-FEN2-025.0*5.0mm from Ledman under the inspection report No. of w2012-615(b). According to the inspection, the Center tested 60 sample products in total under the required testing conditions, 23 passed the test while 37 others failed.
