I don't have experience with anything but Vista fixtures and transformers new, I liked their guarantees. I have rewired different manufactures transformers so voltage would be between 10 and 11.5 at the end. I have took different manufactures fixtures and pieced them together (like 5 old fixture 2 working take the other three and come out with one or two that can work) to make them work for people while installing new lights. If I was to try a new manufacture what would you recommend and why, what do you use mostly and why? Am I missing something from some other maker ?
