Umm, yeah 
Then that tank is at risk of being carnapped (or tanknapped) - by flashaholics. 
I am pretty sure the Supbeam X60 will get you there.
whatchall think??
Hi, i think the version of Racer86 Tk75 will beat them all even the tk75vn kt, its running about 6.6Amps each. And if he dedome those 3 xml2 I think it will give more throw.
Yeah it will beat them all to overheat and drop like a stone in output.
It’s not all about the first 10 seconds, if even that.
Yes, and I believe the batteries sag will happen much quicker than the heat sag. We are talking about just a few seconds staying at maximum output lol.
Where did you get your 10seconds idea? kindly read what he wrote on his thread.
Stock TK75 is a great powerful allrounder, now, this light is in a different league. Im not kidding when I say that my BTU, SP03, Lustefire 3xU2, all modified “hot-rods” are now pretty much obsolete. As in, this TK75 outperforms them in pretty much every possible way. This will probably make some of my incoming Supbeams X40 and K40M obsolete as well (hopefully Ill like the thinner carrier enough to keep them). This might make some other lights that I have been planning mod obsolete as well. This will also out throw X60. Naturally, It wont run as cool as a much larger light. But it will fit in my jacket pocket, and that makes it into a light that I will use much more compared to something that is larger.
Used in a mild/cold winter environment with some wind or maybe rain. It might be able to run at 6,6A without step down from full to low batteries. Now, late summer/early autumn with some wind I can use it for around 6-8 minutes before it steps down. Wait until it cools 5 degree (which is fairly quick) and I can crank it up again for a little while if needed. I can disable the feature, but I prefer to have it there for safety.
If you think 6,6A is over the top, or generates too much heat. Then its easy to adjust it down to 6A, or 5,6A or… 5A …. Well, easy once you are confident in how to operate the driver and how the menu system works.
I hope he has found something after a year of searching!
Fern, heat sag is not an issue outdoors. When it is, the light steps down. And as already quoted that will take some time...
My numbers are "ansi numbers" indoors. No startup up bragging numbers typical for unregulated hot-rods with fresh cells.
The light is specifically built for real life continuous outdoor use with high capacity cells and does so very well. With all the modes (and different UI`s), user adjusted temperature, user adjusted peak output, its easy to tailor the light for any type of use and environment.
bibihang, battery sag is not an issue since its pretty much properly regulated. It will push out around/close to 5000 lumen even when cells are fairly low (some cells will be almost fully drained at that point). When it finally does go a bit down on output, it will still be RC40 level. This is one of the many reasons why I think the light is so much better compared to most unregulated hot-rods that are only super bright with the right freshly charged cells.
Most of your worries have been talked about in my thread on the light.
I have been thinking of making an RC40 R86 edition. But never had the light in my hands or seen a teardown, so I cant say for sure how my plans would go if I decided on it. Its very tempting though. It would basically be a lot like the TK75 R86 edition but with some necessary tweaks. Based on the same taskled driver, but bigger, brighter and badder. :D The more I have been thinking about it, the more im tempted to pull the trigger on one..
Cheers, you came to the rescue! you explain it very well about your mod Tk75 R86, saving some money now! I like the overall performance of that said taskled driver.thanks :party:
I used to really lust after the RC40, but I’m glad I got the X60 instead.
More thought had gone into the RC40 design (imho). While it's true the magnetic ring is more convenient, the light is very awkward to use one handed. The tube on the X60 is also very slippery. I used both lights this weekend, and while both worked well, I found myself both using, and giving the RC40 to others to use a lot more.
Also having preset power levels on a light insures that you can manage your battery time far more efficiently. That is very difficult to do with an "infinitely" variable control ring.
The power pack also means not having to juggle six batteries. That Fenix choose to release the light with the now very dated xmlu2's and crappy batteries in the pack is in large part the reason I suspect it hasn't done all that well in sales. I definitely would not have purchased one if it hadn't been modded.
