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.
I actually wished they put U2 or U3 into TK70 design, and user can choose to use 2/3/4 x 32650 or 3/4 x D cells.

Then it goes up to this.

I think you want it, but you don’t need it. All your gaining is a smaller light and a bit more flood. The TK70 out throws it by a lot. With the great collection of lights you have you could wait for the next best thing to come out, which you “might” need 
The TK70 came out nearly a year before the U2 did, so you can see why they didn’t.
Didn’t they update the TK41 though?
Yea your right. And I have the Elecktro Lumens ST90 Search&Rescue Extreme coming anyway. It should kill my TK70 in throw.
Yeah I cant wait to see that in action. I know you will have some pictures punishing your neighbors. BOOOOM
