We have already recieved your return of 53 pcs of defective LED on 19 Feb. There are 2 dead , 49 poor LEDs in this defective goods. Among that 0.5 pcs is broken and 1.5 pcs have different spec.
After carefully inspecting the defects we found that the fading of the LED itself is the reason which caused the poorer illumination. We also put the 2 dead LED into further examination and are still waiting for the result.
We suggest that the quality of the source material is the main reason of these defects. We have already informed our suppliers and will have extended life time examination in further process.
Your satisfaction is our goal.
