In the light supplied were of the 6 screws that hold the lamp two incomplete screwed or already set wrong during the delivery. After mounting the light these two screws were not really fix. Better, I said it did not really trying because I was afraid that the thread can not cope. I want a parade of light not really expect as a second now and growing well could be even more difficult. Brightness is very good indeed. Appearance is also good. If the quality of the system would fit would be a great light.
