UPDATE
These are the brand new more powerful M140 diodes from the new M series projectors. They have shown a great increase over the previous A140 didoes that everyone else is selling. It is believed that these are the new 1.7W Nichia manufacturer rated diodes instead of the 1W Nichia manufacturer rated diodes that everyone else is selling as 2W over driven diodes. See this thread for details.
