What were the threads like?
How do i explain this lol.
They are good? Cut well so no grinding or mismatching on mine and smooth i did lube them.
At the same time they are thin but there are so many threads it shouldnāt be an issue.
It takes 13 turns to undo the tail cap compared to 4 turns on a C8 lol i guess the battery tube is twice as big.
Damned fine host, easy to mod.
Beefy enough to handle some decent heat, too.
I donāt have an A8, but from the listings Iāve looked at, the āYupardā version looks like they cut some corners.
Iām interested to hear what other people suggest.
F13 are well priced and easy to mod. Hereās mine
I am on the road to do something like this 
Well at least I hope so 
My F13 should be here this weekā¦
Thanks for your post, It gives me ideasā¦ And all others too!
For the price I will probably pick up the A8, B06, and (2) F13ās (one left stock and one to mod with a xhp35).
Thanks for all the Advice and comments.
I might pick up an F13ā¦ seems like a great affordable light.
I love the F13ā¦ as a host.
Out of the box, it kinda stinks. Cheap minimally regulated driver, crappy annoying UI, probably an undersized LB emitter. New driver and new emitter, and itāll kick arse.
Using the F13 as a host for a beginner, what would be the ideal and exact parts that the F13 could handle in say a XHP35.2(35) or 50.2(50) or better, like from Kaidomain. As little work as possible the better.
LED on star, and wires on board. So pull the old, add paste, solder, push star down stuff wires in and solder board in. Correct?
This would be my first flashlight mod.
Thanks.
It doesnāt sound like you want this for a modding host, how important is the tail switch?
This one looks like it meets your other requirements besides the tail switch, including the price ($23.71)
EDIT: (TBone already suggested above, but hereās a nice photo anyway!)
OK I must have missed this post. This host might be interesting.

Right now I am not able to reply to individual posts so.
Beam0, I do need the rear tail button since the light will be in my pocket exc and it will be less chance of turning on accidentally. The pic you link looks like the Trustfire A8 but with the side switch. I ordered the Trustfire A8 yesterday.
Thanks Beam0
Beam0, thanks for the KL-S26 link.
Thanks Again.
I will stick with the Ultrfire F13 as my host. I believe it has a great look and battery I am looking for. Now to mod it to put out some light.
I also ordered an F13 for mod host yesterday.
