Whether it really is a Cree XM-L T6 LED, I do not know - seems to me it is not bright enough before. Unfortunately, the mechanical quality is pretty modest. The adjustment of the focus goes with me only in one direction - then I have to unscrew the entire head to position the lamp again properly. The lens also has a very distinct Macke, which can also be seen in the light cone.
Because I wanted to have the part just for my toolbox, I'm quite happy and not send it back - yet I wonder why the part sold so.
