It was a mistake. I have a test box where I can push a few buttons and switch between different types, numbers and colors of LED's. I use it to test drivers that are new and about to be installed into a product. I also have some power resistors in there which are my dummy loads. I pressed the wrong switch and connected 12 IR led's instead of the dummy load. I put 23v through 2 strings of 6. The have about 1.8vdrop each typically.

It was not a good night.
