Matches the color of the new FDE m2.0 nicely and by the way universal mania has them for $196.xx delivered right now. Yes its the 600 lumen model.  That is all.

Which part does it match, my FDE 2.0 is at least 3 different shades

Matches the slide perfectly to my eyes. On a side note to avoid any frustration. Take the spacer off the back of the battery cap and use the P insert. With the spacer installed using the universal insert the trigger guard puts so much pressure against the switches and battery door it causes the switches to malfunction. Kinda weird. I put the light on straight out of the box and it worked perfectly as i checked function. Put in safe and pulled out later and no function. I was WTF. Pulled light off pistol and it worked. Put back on pistol checked function and it worked. Put it in the safe and checked it again in the morning. No function. Pulled light off again and it worked. So i switched to P insert and removed spacer and it has worked fine since.
