I see an oval board with 2 wires. How are the wires attached to the board on the back. Socket and pins?
I ask because if it has a quick disconnect pin/socket, then you might be able to replace to whole board and it does not have to be oval to work - just has to fit into fixture. I did similar with my EVC.
Check out SuperBrightLEDs - dense site, but I think this link will help.

On most you will find info on current draw, color temp (K), beam angle, lumens, etc.
