The best light out there? December 27, 2022
It has been my daily carry in an industrial environment for almost 3 years. It has been dropped, hit, run through the washer and most recently thrown on the pavement at 50kmph (electric unicycle cut out.) I know there are tougher flashlights out there- but this one will survive any reasonable (and some unreasonable) abuse.
I use the magnetic cap to illuminate areas holding it in place for hours at a time. Its bright enough to gauge the fluid level in a 4 million liter tank yet has an unreal run time if you don't have it cranked. While a little heavy for some people's edc preference, it slips in a side pocket of your Carhartts or a jacket pocket and is the best, most versatile light you will ever own.
I own a few lights that Hank makes. All are quality, but this remains my #1 recommendation. This is also a good place to mention his customer service. Twice I placed an order and realized that I preferred a different led. His communication was always fast and he swapped it out before shipping.
I can't say enough good things about this light (or any of the lights Hank produces.) Buy the stainless bezel and admire the proportions of this light, the precision machining and the flawless finish (at least until you throw it on the road and gouge it a little.)
They are beautiful examples of functional art. -

A perfecty crafted high quality flashlight May 16, 2021
After a problematic shipment (due to Brexit, perfectly handled by Hank) I received my flashlight today. I have to say the design and build quality are perfect, the LEDs are selected exactly as requested, I can recommend this product without a doubt, and Hank has helped a lot by handling delays from Brexit deliveries. Thanks Hank, this is not my last flashlight from your shop!

Amazing and the highest of quality. December 26, 2020
I purchased two D4V2s, one full size and one stubby and I'm afraid I might to buy one if everything Hank has to offer. I can't recommend this light enough, it gets good battery life (settings dependent). The blue is absolutely stunning.

This is the hotrod of lights. December 23, 2020
Wow, just wow. This light is bright and has a great throw and appropriate flood.
The aux lights are the bells and the 4 emitters that are so bright they heat up enough to burn stuff are the whistles. That being said, becareful this is not a toy don't let kids play with this, they can go blind or even burn something if not their hands.
I think I'll buy more just to have the power of the sun in my pocket. -

Its my EDC December 17, 2020
I dont own many lights and because of this one I dont think Iam buying more in near future :)
Love the weight/size and all the perks of anduril (have some glitches with firmwire but manage to work around it)
Its ergonomic fits perfectly in my hand and switch is easy to operate. So small but eficient regarding output and temperature protection which you can manage to your own desire.
Hiking, biking, around the house its my daily carry. Magnet is strong and comes handy in many situation.
Hanks is responsive and ready to hellp so many thanks to him for this amazing flashlight.

Hank, Bringer of Light. November 20, 2020
Hank is a rock star in the Flashlight world. This product is by far the best flashlight that I own and I am utterly impressed that one man can out preform all the flashlight companies we have. Nitecore, Fenix, Olight, Thrunite etc. are all hot garbage compared to what Hank puts out.
Hank probably has tons of illegitimate child due to the amount of poon that he slays with his flashlight game.
Finally, Hank's flashlights not only light the darkness. They light your soul. -

First light to grab when going outdoors @#@ August 9, 2020
The d4 craze is real: finally a manufacturer has made it possible to get the features of a homemade pocket rocket into a production light. The V2 running Anduril is both intuitive and packed with features. The d4 is astonishingly bright for a small light, but only for a short time -- this is where the d4s steps in.
The D4s is capable of controlled voltage output up to 500 lumens. The D4 pocket rocket only has digitally controlled voltage up to 150 lumens. This is the heuristic you should consider when comparing the two lights, as it is the brightest effective runtime for extended use.
This comparison denotes the delineation of their intended uses: the d4 is a great EDC that can achieve a lot of brightness in a pinch, and the D4s is the outdoor model with the necessary bulk for sustained use.
The D4s battery and extra thermal mass allow you to run higher levels without overheating, but will not fit in your pocket. I adore the shorty tube for the d4s, in which case it works great in a Molle pouch off the belt.
My advice is to get both: the D4 for EDC, and the D4s for outdoor use. Congrats on a great product!!! -

Amazing light May 26, 2020
Bought the 5000k sst-20, love this flashlight. I have a couple fw3a, astrolux, thrunite, olight, and this is my favorite light by far. Size, battery power from the 26650, and brightness and heat dissipation are all pluses for me! Want to buy another with a Cree in it, but really wish there was a way to get the green body color, I bought the gray and wish I would’ve bought the green since it was available at the time. Probably will never see that available again, but still my favorite light, cannot go wrong!

Must have for bragging rights :) April 24, 2020
I bought it off somebody, as soon as I tested it. The blue colour is my favourite. haven't touched such a nice matt anodisation yet. The build quality is flawless. The implementation of the UI is also what I consider hight tech that must be present in a 2020 light. It is a shame that it stepps down rather quickly. But this is phisics. I'm sure in the future we will have more efficient leds and you guys will still be putting them in great flashlights. p.s. Also put in an order for the smaller D4v2, just out of curiosity.

Awesome! March 24, 2020
This is an amazing little flashlight..especially for its size..! Everyone who has seen it is amazed by its power, and with the 26650 batteries it has a decent run time, even on full power and the build quality is excellent. I just have to be sure to keep my eyes on it, because I suspect it could easily grow legs and walk away, if you get my meaning..! Thanks Emisar for making this..!

Freakin lovely flashlight March 24, 2020
Received it yesterday, and I just love it!
Way more powerfull than we really need in our life normally, but for the fun when you activate turbo it will astonish your friends for sure.
Took the XP-L-HI V3 3A 5000K, it's the perfect mix of throw and flood for me, and no tint shift. And yes 4300 lumens is f*cking bright -

Slightly big for EDC BUT excellent winter carry light January 4, 2020
the 26650 battery makes this light too big for EDC when you are running for groceries. However this is perfect when you are wearing a bigger coat. THen Anduril Ui allows for you to basically do anything with it and if you buy the adaptor, you can input your own coding into this light. definitely would buy again from Hank as he is always insanely quick with email responses and attentive.

Annoyed
Battery is not included January 1, 2020
Sent this link to my wife so she could purchase it for me as a gift. Could not be more annoyed, while it says batteries not included (we missed that), that is fine. How about you offer the batteries for purchase on the site... Not only as an add-on..... Ill have to shop somewhere else i guess, thanks a lot.
Sincerely

The Perfect EDC. November 3, 2019
This is perfection. being the larger style it supports the larger higher capacity 26650 lithium cells.
as weight goes, its nice to be able to "feel" it in your pocket, yet not have it heavy enough to pull your trousers down.
The Anduril UI is again perfection.it has some ammazing modes like "flickering candle mode" and "Lightning mode" where it mimics lightning flashes.
this gets above 5 stars in my book. absolute perfect flashlight for every day use.
Thank you for making this amazing flashlight!
