Need to know Reflector size, driver and mcpcb diameter’s? Also where is the shelf depth in relation to the outside of the head? Something like this… 
Yeah I wanted to include that info. Hopefully I can find my calipers today
Great review still hoping to get to use mine this weekend. 
PD, can you run the 26700’s in this? I can run the Imren 26700’s in the Jax X6 and L2 with the new 2x26650 tube with out those copper washer’s. They pull .8 of an amp more then the Efest 3500 and 4200 in the L2 XHP50 4300k for 8amps, according to the Fluke 36. Get rid of the inner lead holes, around the mcpcb and have a full shelf. It would be nice to know if the reflector is the same size as the Jax X6, I have a couple extra mint smooth reflector’s. 
Thanks PD! 
I’m thinking XHP50 (shaved?) and FET driver.
Ok, I found my calipers.
Reflector OD: 67.42mm
Reflector ID: 62mm
Reflector Height: 49mm
Lens: 67.8mm x 3mm
Mcpcb: 31.5mm
Driver: 29.5mm
Driver bay height: 17mm
The internal shelf is right where the head starts to narrow down to meet the section that holds the button. There are 1 or 2 deep fins there, the deepest fins on the light.
Two KK 26700’s are just a tiny bit too long.
Thanks. I don’t have anything on my radar at the moment, so I think I will get into that group buy if it happens. I haven’t gotten involved in one of those in a few years.
Thanks PD, the reflectors are really close, very cool!!! It’ll work!!!
Cool.
I must say, when I saw it I immediately thought the head design looked a lot like the X6.
Does any here have experience with the Olight M3XS‑UT Javelot? If yes… how does the Thorfire compare in these categories:
Throw
Spill
Form Factor
Thx!
LONG LIVE BUDGETLIGHTFORUM!!!
PD is it possible to get a Pic of the driver?
There is one in the OP (click for larger) or are you wanting a different angle or something?
Huh, it wasn’t there when I last looked, don’t know if it’s on my end or BLF’s, but pic’s aren’t loading, or loading slow? Thanks, I see it now!
Sorry I missed this question earlier.
I don’t have the Javelot, but my understanding is that they are totally different lights. The Javelot is more of a dedicated thrower, whereas the S70 is more of a mid-range light with a wide beam profile. I believe the S70 is much bigger than the Javelot as well.
Great, thx for responding pilotdog. Great review, I wish I had your knowledge.
Does this light require button or flat top cells (or either) ?
Also as I will have to buy new cells for this light as I presently don”t own any 26650”s any recommendations on good cells.
Short answer: button tops
Thanks for that pd.
Any recommendations on a cell.
If the Cometa group buy I am in also takes button tops then I will need to buy 4.
As both lights have low voltage warning & cut out features I imagine I don”t need protected cells.
I’m not the best person to suggest a button-top 26650, I’ve never had one.
I plan to buy some of the Basen cells freeme is trying to start a groupbuy on, though I think they are flattops so I’ll add a button to one of them.
The Cometa should take flattops though.
