What are you meaning about better thermal management?
It is always easier to cool off smaller cells rather than bigger cells, and battery packs using smaller cells are more reliable.
Yay for the strong magnet! Tail light magnets are never strong enough for me and I always have to add an extra one. Nice light!
TK, thanks for taking the time to show us how this D4S will become 
I’ll wait for the final specs to be disclosed, but what was advanced make me like this light! It will be my first in 26650 format, so I’m curious about it!
BTW, those changes on the UI seem nice and, in some way, more practical than on the D4!
Let’s seen when it finally comes to public :sunglasses:

This looks like it is taking advantage of your Aux LED pin 3 feature of Anduril?
WOW :heart_eyes: :+1:
Well done Hank! I can’t wait to get my hands on one of those bad boys.
- Aux LED’s look awesome! :laughing: I really like the blue. Red might be fun as well. A few options would be cool.
- I’ve read the magnet is “optional,” does that mean its removable from the tailcap?
- 26650 battery config is great. Is there going to be a short tube offered for 23650?
Thanks TK for the review!
Yourrid, pretty sure TK said she got two tailcaps, one with and one without the magnet.
One thing I like about the 26650 format is the extra room it gives to spread out the LEDs on the MBPCB.
Although, I have never owned an 18650-based triple or quad, I have always been suspicious that the optics on some of those lights are covered a wee bit by the bezel. In practice, I doubt it makes much difference in output, but, hey, every little bit counts.
Thanks for a great review.
Very cool light! The larger mass should help a lot with temp regulation and extend turbo for quite a bit. I hope to see a 21700 tube for it.
Well there goes the flashlight budget again, gotta have one of these now.
Tagging to keep track of when they are going to go on sale…
Maybe these are the LED choices.
On Int-Outdoor there are new Led-Boards and looking like fitting the D4S. Hi (4000, 5000, 6500K) und Nichia (5000 90CRI)

How difficult will it be to exchange these cyan coloured micro-size LEDs by red coloured ones? Are these LEDs hard to get or is it a standard LED that can be bought at Mouser, Arrow, Kaidomain and so on?
I wonder why Hank took cyan/blue LEDs. Red light would be better for maintaining oneself’s night vision ability and - IMHO - looks more fancy like those unaffordable Oveready BOSS lights. Green light would also be a better option for the human eye is most sensitive on the wavelenght of green light (~ 550nm). So, green light even at micro-lumen-level would be far better visible than blue light.
Maybe all this has something to to with John Rambo?

Has iOS v3 a reset to factory defaults function?
Thanks for the review.
This looks great, longer high lumen runtimes than the D4 with more thermal mass. Makes me glad I haven’t snapped up a D4 or a different 26650 light yet so now I can say I need this for two reasons.
Had to smile, Cujo needs mo powah!
hm…but this is not an edc anymore:)
Why not vresto? A belt sheath will put it at hand at all times and you’ll forget it’s there til you need it. Kydex or Holstex can easily make a horizontal holster to carry it on the belt or the hem of pants or shorts, works very well.
Edit: Know any LEO? Ask them what they carry every day…… come on man, Cowboy Up!
for 26650 i would rather buy DN70 or so…for me more practical.but surprised,that this one is so throowy…
