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
How come there is no battery holder picture and show how it can be extended? The design is not finalized yet?
It is time to quit buying flashlight for some months, saving for this one. 
I’m starting to think you’re a troll. Most likely the bezel of the battery compartment unscrews and can be screwed into the front of another battery tube.
I am not talking about battery tube, I am talking about battery holder most likely plastic one looking at other Fenix product. It is mentioned in Fenix website.
I would think it’s just stacked on each other in series and the circuit can buck down from 12v.
I hope they have proper battery holder as I don’t like the design for example Skyray King that actually let the batteries rubbing on contact with PCB or metal when putting new batteries in. Of course, many like the convenience by just drop the batteries into the tube. I like it either but only for batteries in series with springs where the rubbing radius is very small compare to design like Skyray King.
Does anyone know which is driven harder, the TK75 or the BTU Shocker?
Most likely the BTU shocker, the turbo of the btu driver goes to 3.8A, and can have the DRY driver, which with good batteries ‘goes over 4A’, but I don’t have any light with the dry driver, so I don’t know about the amperage.
The TK75 is probably driven at around 3A each.
I’m thinking it would be more than that, no? How does Fenix get 2600 ANSI lumens?
I believe I read somewhere that it takes 4.2a for a U2 xml to output 1000 lumens OTF. If that’s true, let’s just suppose for a moment that the TK75 may be driven at 4a, which I’m guessing might give around 970 x 3 = 2910 OTF. If that’s the case, and we use an optimistic 10% loss due to heat and lens, that comes to 2910 x .90 = 2619 OTF.
I’m just hypothesizing and I could be totally wrong, but what do you think?
Well… you are totally wrong. A skyray king outputs 2300 lumens at 2.8A per emitter. This TK75 has way more aggressive heatsinking so the conditions should be better than the skyray king.
If you want to assume 4A, then that’s 1150 lumens per LED, but minus the 10% is 1035, thus resulting in a total of 3105 total lumens.
I’m happy with my TK70. I don’t need this one. I repeat, I don’t need this one. I don’t want this one. I don’t think I want this one. It’s not working. Oh well.
Resistance is futile ! Bwaha hahaha :bigsmile:
You got that right.
You got to love the size on this one. I think it looks great. Now all I wish is that they made one just like it in a single SST-90.
Hey, thanks for the correction - sorry everyone for my errors! So, anyway, I can see the Shocker will be a bit brighter (possibly 2900 ANSI lumens?), but I think the main difference between Shocker and TK75 is beam profile. I love the 80 degree beam angle on the TK75.
But I will be the first to admit that the TK70 as of now is still my personal favorite flashlight. I mean how can you not like a light that will light up a street like this. And that is a lot of just the spill since I’m aiming at the trees some 220yds away. Most carlights won’t touch this light.
Oh and that’s a manual 1 sec shutter photo.
