For a reflectored light the furthest thrower is the Dereelight DBS v2 with a 1.2A pill (1S or 3SD). No doubt about it - this is the brightest.
However, LEDs with an aspheric lens can throw further. Downside is that they are larger and the beam is a projection of the LED - ie a square with lines across it etc., and no spill. Of the aspherics, Saabluster's DEFT is the furthest throwing.
I would recommend the DBS. Why? 1) the throw is tremendous. I highly doubt you will ever want more once you own it. 2) Body. It is smaller, and more of a duty flashlight, whereas with an aspheric you have a larger light, bulky lens, etc. 3) (edit - runtime for the DBS is actually worse, because the DEFT uses batteries with a larger capacity), and 4) if you want modes, the DBS has that option, while the DEFT does not.
But that's just my opinion
. If throw is all you care about, it's the DEFT by a huge margin.
