Good 1×18650/20700 host?

Ultrafire F13. Pretty tight hotspot, throws quite well.

Out of the box it kinda stinks. Cheap unregulated driver, crappy UI, passable LED. Beautiful host, though. Mod it, and it kicks ass. Dedomed or HI version makes the hotspot smaller and tighter for even more throwiness.

Convoy C8, the de facto standard for compact throwers, easy to mod. Go hither, mod the crap out of it.

Just be careful, as different versions can take different sized drivers. All the ones I have take 17mm drivers, but some newer ones take… unno, bigger ones.
