Made in Italy, but M10 metric mount not US 3/8 inch
Generally, i was delighted to find these light sockets made in Italy and not China. Delivery was pretty quick by DHL from Italy, and the sockets seem well made. My only issue is that the bottom of the socket is a female threaded connection that ALMOST fits onto a standard US 3/8 inch threaded lamp tube, but is a metric M10 1.0 thread that doesnt really fit (although it can be jammed into the US connector). I emailed a question about this to the website but got no answer and took a chance - it didnt pay off, but maybe i can use these sockets some other way.
