What a superb light.
I wish Fenix could drop those awful side switches though as I’ve had so much trouble with them on my TK41.
Magnetic control ring please Fenix 
So true. I don’t like my TK41s soft power switch at all. It is erroneous.
This will be an early Christmas gift to myself.
its going to be a beast!
This is very tempting.I wonder how it would compare to a TRJ-12 in real life?This has been a tough month for me, just when I think I’ve got all the flashlights I want, something new(and more expensive)comes out that I like!Budget light my pooper!-Rick
I think its 4 / 8 / 12pcs 18650s >)
I believe the price is about 220 dollars as well, considering fenix build quality and compared to say nitecore tm15 299$ I think its an excellent price
going by them photos it does look like it could possibly take 12 18650’s.
My god, if that’s right in the wrong hands this could be a death trap imo.
The King is dead. Long live the King.
87.5 mm per the specs.
One thing I do like about the TK70 is that it is a lot more accessible to mainstream. Anyone who wants a really strong light, but doesn’t want to deal with wierd 18650/26650/etc batteries can use it just fine.
I use 10,000mAh accuevolutions and it has great runtime and works fine even with 3 of them.
Its neato that they have an 18650 version that is more compact I suppose but theres already been quite a few such versions. The main difference is that this one will have the same TK70 throw due to the large head, vs a wall of light like the skyray and other coke-can-looking things.
So.........
potentially this thing will have almost 4 hours of 2600 lumens with all the extensions? Thats CRAZY!!
Or 600 hours on low :O
Somewhere I read that TK 75 is flooder than TK70 but TK70 has more throw than TK75 . Undoubtedly it will prove more useful .
Has anyone heard of any chance of 18650 form of TK60 ( TK 65 ? ) .
Even Fenix thinks so...
TK70 130kcd
TK75 92kcd
God I hope what you posted is true.
Because from what I read, the BTU Shocker has the TK70 head.
But because it’s driven harder, it should out throw it.
Fingers crossed.
Thanks ChiX, I guess I skimmed over it too quickly.
I wonder why they opted for the smaller head, also by the pictures it looks as if it’s half as deep too, maybe people had trouble with the head being too large and shifting the weight balance of the light.
I don’t want to hijack, and I know I’ve been advocating the btu shocker for some time now, but I really can’t see any reason to refute it - from how I see it, it’s going to have the same throw as a TN31, more than a K40, have close to triple the outputs, which also means way more flood, and a bigger hotspot. This ticks all the boxes for me, because it has lower modes too and no strobo/sos. Only downside for me is that it only takes 3* 18650s instead of 4.
Okay time to talk about the TK75. It takes 4* 18650s, 8 or 12, which rocks for runtime. 3 hours 45 minutes, pretty long, weighs less than half the shocker (510grams vs 1200grams). It doesn’t seem to have lost much throw though, it has 92kcd which is still pretty high. And they’ve upgraded to a U2!
This is such an odd choice for the newer/better light to throw less than the old one.
I would say for 90% of people out there flood is more important than throw so haveing less throw should mean this has more flood so for most people a better light.
I too would say that flood is more important to most. Even though throw is REALLY nice to have, you just can’t beat flood when you’re trekking or something. But not having to move the light around to see your way and just hold the hotspot in front of you while having all the spill illuminate everywhere else it’s so much more convenient.
Even though the previous TK70 already did this, I guess they wanted a brighter spill
