Unfortunately, there is Amazon failed, despite a threefold order and replacement to deliver a defect-free copy: on all lamps clear signs of use as initiated or bent metal corners, dust edges, badly wiped grease residues, kinked cables, scratched mounting rail and a soldered holder!
The first time you think of a mistake, everything else is already bold when you're striving to be the most customer-friendly shipping trade. Conclusion: All three lights went back to Amazon, lamp ordered separately, as currently probably only 2nd choice / exhibition item is in stock, among other things.
