this is where i got mine
no refferal link
people who dont own the light will just say im full of bs but the TR-1200 will throw and has good spill, on the same night i tested the Jetbeam BC40 i got 250 meters (273 yards) if you dont belive me this known seller claimes 300 yards (274 meters) here is the video
i belive my conditions where more clear then in his video but i claim less usible range and the TR-1200 will out throw the Jetbeam BC40 but i used the same measuring methods to test both and the on the same night we tested TF C8 XM-L, KD C8 XM-L, TR-1200, UF-2100 XM-L, USA168, Jetbeam BC40 and the TR-3T6 3 x XM-l
the torch with the most throw on the night was the TR-1200 and the TR-1200 has a constant current driver and is driven in the same way as the TR-3T6 so its got a good driver and can be used for long runs.
