nice focused light pattern which I love. Installation of the grid results in a smaller light spot yet. Diffusing sock softens the light as expected.
It became apparent that the nut embedded into the dish (and used to attach the dish to the mount) is a weak point of the entire mount - it is already loose which results in the dish wobble even when the nut is fully tight. To prevent this I used a nylon washer from the original parts set. I increased the washer's internal diameter to ensure it exerts the pressure on the dish and not on the nut.
