Here is a small sampling of fixtures and wiring I removed this past season from existing systems installed by others. Most of this stuff is about 8 years old, some of it brand name and not what I would call quality. I haven't been around that long but first question regarding the fixtures: Do you think manufacturers / distributors have upgraded the quality of their fixtures in the last few years? Second question, this one regarding the quality of installations. In the picture is one set of connections, all one big splice using regular wire nuts wrapped with electrical tape. And one of the fixtures has a square pierce-point connector. Again, these are from installations about eight years ago. In your opinion, has the overall professionalism of lighting installations improved in the last few years?
