I agree that I would not consider anyone who attends a one day seminar an expert or a qualified installer. What I am saying is that I do not begrudge anyone who goes to these seminars to help them get better educated or as a starting part for their landscape lighting career. Everyone starts as a novice, it is what you do from that point to make yourself a true professional that sets you apart. I went to pond, paver, and lighting seminars as my first point of education when I first started offering these services many years ago, but that's not where I stopped my education and training. Industry standards would be great. I would like to see all fixtures UL listed. We all know that doesn't happen, yet many contractors still buy and install them. I would like to see all installers certified. Same thing there. The question is not only how it's standardized but who enforces it, and as always, who pays for it.
