What is the fattest head and tightest beam flood-to-throw available? It’s for an IR project, the LED and driver will be scrapped, so I’m just interested in the optics.
Thrunite TN31 have a very large head with good relfector for throw.
Is this your question?
Does the TN31 have adjustable focus? Plus, I’m looking for a single 18650 cell body - guess I should have stated that part.
Quite simply no. It sounds like if you want a really big head that you may have to go custom built.
Basically the question is the following:
What’s the largest head 1x18650 aspheric zoomie currently available?
Unfortunately, I usually look for small heads to fit in the pocket so I don’t know the answer.
See post 6 and 7 to start you off.
Its 43mm head, 26650 but am sure you can convert that to 18650.
43mm is the same as a Yezl T9, which I have. I was hoping for something a little bigger. Plus Taobao scares me.
Not too budget friendly, but this: http://www.banggood.com/WOLF-EYES-Seal-Hunter-CREE-XM-L-U2-1000lm-Zoomable-LED-Flashlight-p-919779.html
When I saw your headline, the first thing that came to mind was “Donald Trump”.

My SEAL just arrived from banggood. I paid the extra for DHL shipping and it arrived on my doorstep in a week. Stock throw is 131Kcd with the aspheric lens and 32Kcd with reflector. This is exactly what the advertised specs are on the very nice instruction manual/spec sheet , printed in english.
Then it gets torn down and modded with a prototype SBT-70 RED emitter on the way from Luminus. And hopefully I can get extra pills machined to do an IR version as well.
I hope to do a full review soon.
Crelant aspherical head.
OMG that is a big ass aspherical head I’ve ever seen! It has 83mm head!
But it is a 1st gen XM-L U2 stock? XP-G2 dedomed + 4.2A should produce >500kcd.
It’s an XML2-U2.
here is a photo(sorry for the bad pics) next to the T20
You could add Gene Simmons and Ted Nugent to that list 
Thanks for the photos kevind43. Is the focus adjustable with the big aspherical head?
I wonder why nobody talk about this light other than the more popular lights but with smaller aspherical lens like Crelant and X Searcher.
