Surprisingly awesome
I'm really thrilled with this light. Didn't know what to expect with Anduril but it's intuitive and fun. Very well built, quality workmanship.

But in all fairness, the KR4 was cheaper than the PD35, so there's that. Yeah, I guess we can add flashlights to my list of rabbithole hobbies ( next to mechanical keyboards, firearms, knives, watches, 3d printing and coffee). So...thanks....I guess? ¯\\\_(ツ)\_/¯.
What are some lights you think have an incredible performance for their size? (Any size) Runtime, Lumens, Throw, Spill.
Emisar D4V2 / Noctigon KR4 (super bright in small package). Noctigon KR1 (super throwy in small package). Thrunite Catapult Mini (super throwy in small package). Fireflies E07x Pro (not the smallest but still mind blowing brightness for the size, especially with low CRI emitters).

Noctigon KR4 Review — Everyday Commentary
July 11, 2020 by Anthony Sculimbrene There are two vastly different flashlight universes out there and rarely do the two cross paths. For many years, I have been comfortably ensconced in one but mindful of the other. Over the past three months, I have decided to venture out and I have been rewarded ...
My budget is around 80 -ish and I am thoroughly sold on the Noctigon KR4 (Al body) with SS Bezel. But, jumping USD 44 for a Ti version looks like a good deal.
One of the best uv lights I've seen.
On par with the d4v2 uv mule and he even sells the filter which I highly recommend

FW3A in 2021?
I'd say unless you ABSOLUTELY have to have a 1" diameter light, the Noctigon KR4 is just better. One more emitter, more reliable, better build quality, more emitter options, aux emitters, slightly newer version of Anduril, slightly higher regulated output, flashing pads, and better stock clip.

Noctigon KR4 in Deep Red
Here’s the short of this: the KR4 is not a great light because of QC issues which still seem to plague it, but the SST-20 in Deep Red is a heck of a lot of fun. And I think probably the third light you need in your collection — it’s weirdly my most used light at home now. Find one here, but get the D4V2 with the SST-20, not the KR4

Hot take: I don't like using the D4V2
Noctigon KR4 Ti. I have low like (2 lumens), medium (around 100), high (around 800), and then top of ramp (around 2200), then turbo. ​. The light can sustain the 800 lumen mode which easily lights up my entire property from the street to the back fence (I'm on two lots, so the second lot is all grass.
