I received the lamp and in record time, but it was not working. After several attempts I realized that the light bulb was not connected to the onboard connector on the module !!!! Not wishing to return, so I had to use ingenuity and delicacy to remedy this defect. It is unfortunate that the product has not been tested in manufacturing because it would not have passed this test. But I hope it will give me satisfaction as long as the original part (about 700 hours at full power).
