Am I wrong when I say lh351d is a better flooder than 519a? I like the tint better with 519a but I’ve heard it’s not as wide/flood as the lh351d.
519A is still pretty floody, and has a better tint and higher CRI than the LH351D, but with less output. In lights with TIR optics, there will be a very wide spill beam for all emitters. However floodier emitters will have a brighter spill beam and less bright hotspot.
Hank, do you offer D4K as mule with 16x E17A 1800K or E21A 2000K? If so, would a boost driver make sense, too? Hoping for a positive reply. 
It's right there in the "DESCRIPTION"
The boost driver upgrade is available for the SST-20, Osram W1/W2, Nichia 219B R9080, as well as 519A version, each LED receives 2A current. The driver is not compatible with Nichia E21A, Nichia E17A, and mule versions of the flashlight.
Also hoping for a xhp70.3 D4K, mule or shallow op…
I’m afraid that you have to make custom D4K by your own, buddy.
Awesome. Thanks!
Hank, can you post a picture of a D4K next to a D4V2?
I just saw on Reddit D4K next to a D4V2. I like it a lot but the only thing i didn’t like is the clip.
I have a feeling it won’t fit easy in in the pocket…
here it is:

How come they both have same thickness ? Tube is thinner on D4k?
D4v2 : 95mm(length) * 28mm(head) * 24mm(body)
D4K : 103mm(length) * 28mm(head) * 26.5mm(body)
It's almost the same, but little over 1 mm thicker for the tube on both sides.
The head is the same, as the D4v2 is quite large for the 18650 (it just got a little bigger hole for the tube)
Hi, does the DM11 come with a tail magnet? I see no tick box option for one, and I could find very little information on whether it has a magnet.
It does not have a magnet. The only way to get a DM11 with a magnet (from Hank) is to also buy the 26800 tube & magnetic tailcap.
Hello, I’m new to the forum, although not in the world of flashlights, I’ve been a member of forolinternas for some time.
As in this forum and thread you are a great connoisseur of intl-outdoor flashlights and leds, I would like you to advise me which led to choose for a D1V2 of those eligible at no added cost, that it be a good launcher and 5000K.
Excuse my English, I use the google translator.
Thank you very much in advance.
I would strongly recommend considering spending the extra $5 for the SFT-40 but if your budget absolutely won’t allow it, then W1 or W2 is the way to go for throw. W1 will throw slightly farther and will not use the battery as quickly, but W2 will have a less narrow, more generally useful beam. Personally I love the W1 but I believe many seem to prefer the W2.
is the DK4 tailcap, compatible with the stock DM11, or DM1.12?
Thank you very much for the answer, but what I wanted to say is that I want 5000k more or less, but without exceeding it much.
I see. Then that limits your options but makes it pretty simple. If the W1 or W2 is too cool (my W1 is around 5800), your options are basically just SST-20 5000K or SST-40 5000K. The 519A 5700K dedomed would be nice but would come down to around 4600K I believe so may be to warm for you. Neither the SST-40 or SST-20 5000K is listed on the D1 page for some reason but I’m sure you could ask for either one.
For what it’s worth, I would probably go with the 519A 5700 Dedomed of those options, but I don’t know how close you need it to be to 5000K.
