Compared to price it is solid. However, there is an angle problem at the electrical contact part with the lighting rail. By bending the terminal board portion of copper to the instrument side until it is horizontal, it can be used without contact failure. Is this a little problem? By the way rail is a Panasonic item
It is a product with no problems using it. Since I do not use a heavy bulb, I do not understand the hold quality, but it seems that there is no problem at all if it is an indoor bulb in the touch feeling.
