I own both and thought how great would it be if they were combined! So I screwed on the tailcap switch to the Maratac TPF light and it worked! And you could combine the other parts together with a Foursevens New Preon Pocket Clip from eBay to create another light with a killer pocket clip. But the clip will not work on the TPF. It creates a gap between the threads, making the light non functional while attached.

Now if only Massdrop offered this TPF combo with a Nichia LED in copper, I would die a happy man!
