Is this LED fixture safe for use with its current fabrication?
Have you contacted them and asked them if they realize those diodes had ends sticking out? There is a chance that this was an early test run and they were working out fabrication issues. If you are getting a trial run there could be a design issue they worked out and there could be a fabrication issue they have not recognized yet.

I would suggest as your first step you contact the group that sent you the device and discuss/report the issue to them. You may save them a large amount of money if they realize they had a fabrication issue prior to a full production run. There is also a good chance they have seen this fabrication issue already and have resolved it in production.
