I recently got these:

No, I didnt get the chinese knock offs, these are the real deal, but a different bin (WWOS) I made a PCB so I can test these things and to give them a bit of a heatsink (its 1 inch by 1 inch in size). I soldered it and added some Arctic Silver to the bottom to make it thermally conductive. Both terminals are isolated from the center.
Now Im doing some testing, but LED voltage seems to degrade with time. It does seem to get warm, but is this why? Testing is performed in short periods, probably 30 seconds max to get voltage readings. Supply voltage is constant, and doesnt degrade. Do I need better heatsinking for even short periods?
Right now (as of this post) I am testing it with a current of 490 mA. It seemed to degrade at 383 mA also.
