A: You've given us something to think about this evening.
The consensus is that these would more than likely not be a good fit for your project.
1. The magnets cannot be flipped. They are permanently framed by plastic. Flipping them would destroy the clip.
2. There is no tracking of the polarity of the magnets as they are installed in the clips since they are not meant to be installed on a magnetic but just a metal surface.
You might receive a sample and see it worked fine only to find that some of the clips work and some of them don't.
What kind of surface are you installing your lights on that it is already magnetized? (This is very interesting and we want to know.)
Sorry, we don't the answer you were looking for. I don't know of any style of magnetic clip that is polarized.
Thanks for your answers about your product. As to your question for me...
I have several non-metallic light frames that have fairly strong rare-earth magnet discs bonded exactly every 4 inches (I made these several years ago). I also have several C-9 stringers to which I (painstakingly!) glued rare-earth magnet discs to the bottom of the socket. The reason I have a magnet on both the socket and on the frame is that the exact spacing is ensured without me having to even think about it because they just "snap" into place in perfect alignment. And, as you can imagine, the "bond" is incredibly strong (much more so than a magnet on a standard ferrous surface).
This will be the last season for these sockets (they are 10 years old). I'll keep the LED Retrofit C9 bulbs (including the new SMD LEDs which are awesome!) of course and just replace the SPT-1 stringer. And the frame are still going strong, too, so no need to replace those. If these mag clips would work, that would save me having to glue 120 magnets onto the new sockets!
I would guess that the orientation of the magnets in these clips would be consistent since they are undoubtedly mass-produced by the manufacturer (rather than random). So I would think that either all the clips in a lot would work for me or none of them would. But short of me buying a bunch and trying them out, I suppose there would be no way for me to know.
That sounds like a fantastic project!
Well, if you're feeling lucky, reply with your address and we'll contact you about popping a clip into the mail for you to test. We would just need to collect shipping charges.
To confirm, C9, correct?
Have a Merry Christmas!!
