Based on who is doing the work, is it a 'budget' or 'what-it-takes'.
Over the years, I have done a few; basically I had a shop capable of fabricating a 'splice box' that was a close or exact match to the design and metal of the fixture. Bushed wiring entry points from the arms, and a stem for access to the 120 volt box......
I also had a good relationship with two (2) lamp shops...unfortunatley....both have been gone, (retired or passed on). Craftsmen are getting hard to find, as well as the various parts and materials needed, with the Big Box knocking out almost all 'mom & pop operations
