My guess or estimation… at least 2400….
For those wondering about outputs from quad lights. Check out this guide from Reddit. Reddit - Dive into anything
Basically, to calculate output, take the output of 4 LEDs at 2A, remove 5-10% from heat, and 10-20% from optics, and you’ve got the final output.
1920 lumens
So meaning base on raw data from Djozz, 519A @2A for 651 lumens… How much we will be getting?
Why are the results of this table for the xpl hi version lower than in reality?
In theory, things are the same in theory and in practice…
The author relies on the test results, but for the xpl hi version he intentionally lowers these values. This table sucks
So yeah, 2000 lumens from the 519A model at 12V 2A seems perfectly reasonable.
All the estimates are lowered by the same to account for optical efficiency (85%), and XP-L HI are lowered to get to maukka lumens from Texas Ace lumens using a 0.925 factor like in this output comparison: https://budgetlightforum.com/t/-/64360/55
The 80cri XP-L HI is adjusted using the ratio of flux bins to estimate the lower output of high cri vs the low cri test data
btw I'm the author, I'm happy to hear any suggestions for more accurate estimates
Because Texas Ace’s lumens are higher than reality (= Maukka lumens, he’s the only one here with a calibrated professional integrating sphere)
Interestingly enough, there’s a very very recent LED tests in which TA’s numbers are very close to reality lmao.

XP-L HI V2 at 2A with Tj = 80C (have to guess here) : 689lm
TA result with TA to maukka factor : 685lm
Pretty close.

Well, you can control this environment and create conditions in which 219b will be brighter than xpl hi, regards 
And where can I find information about the temperature at which other types of LEDs were tested?
Does anyone know what is the correct Anduril 2 build for the boost driver?
Hey guys what’s the advantage to the 519A? Like compared with the E21A R9050 2000K?
For K1 it’s anduril.(latest date).noctigon-k1-12v.hex
For all other boost drivers: anduril.(latest date).noctigon-dm11-12v.hex
Thanks
This is where Anduril becomes too advanced for me.
In my time spent researching the various Emisar/Noctigons that I was interested in, i got it in my head at some point that some dont come with the latest anduril updates and that you can request to have them flashed with it before shipping.
For example, im pretty sure it was in a LuxWad video about the boost driver lights still using Anduril 1? or an earlier version of 2? I cant fully remeber so dont quote me on that.
Anyway, I just recently ordered two Dual Channel D4SV2’s and sent an email asking “Can I ask as well to make sure they both have the latest Anduril 2 please?
I will not be able to update myself.” to which he replied with “Hi, that is fine.”
Im just a little worried now that I may have asked for something… other than what I though I was asking for?
Like, I think the dual channels have something called a FET disabled? I hope I didnt accidently imply that I wanted an enabled version or something other than what Its supposed to be or something like that.
Thoughts?
