This was your first clue not to buy them.That's $.65 per watt.
About 1/4 the going rate from what I have seen.
No they can't, they're semiconductors. Electricity only flows one wayThanks @brazel.
You bring up an interesting additional oddity about these lamps.
The COBs are individually driven, but you can see in this photo that they are wired positive to negative.

Any idea what this is about?
I can only think that it is a feature of these particular emitters that they can be driven either way.
But then, why mark them +&-?
I understand you get what you pay for, but I'd rather not just throw away the remaining hardware.
What this effort brings into focus for me is how far down the learning curve I m when trying to select on LED from the variety of specifications on LEDs.

The red positive black negative.Thanks @brazel.
