It depends if you value really high short turbo output, or value higher sustained output and/or longer lower output run times.
Moonlight is also a consideration. In my testing, the new Boost drivers end up with a moonlight around 0.8-0.9lm. Whereas the Linear drivers typically have a moonlight around 0.1lm. Moonlight is a big deal for me, so in an EDC I’ll be going with the Linear driver personally. The boost driver is very compelling though, and makes the decision difficult.
I would buy multiple of those in a heartbeat. Even single color, an Emisar/Noctigon branded headlight is needed.
I like the linear CC drivers as defaults too, but having the option of a boost driver for every light would be welcome IMO.
On another note, Hank can we get a lanyard tailcap for the DM1.12? It’s a little awkward with the 21700 tube and I think some people might appreciate the additional safety.
That’s a good point. I got my dual channel Hanks in a few weeks ago and their moonlight is surprisingly bright. Probably will go with a single channel next time.
edit: I also keep clicking reply instead of quote smh
Does anyone have a dual channel light and a way of measuring lumens who would be willing to test my firmware changes for a lower moonlight mode on dual-channel lights?
I’d love to get some lumen measurements for how much of a difference it makes.
Is there a time frame for when 519a emitters will be in stock, thank you Hank for yet another amazing looking creation.
When the 519A become available will you offer them dedomed?
Man, I’m this close to selling my PL47 lmao.
I want actual regulated brightness 
I’m very interested but would.like to know about 519 availability too!
Does the DW4 thread with the D4V2 standard tubes (16350 ect.)?
Could be worse. I got a PL47MU not even a week go 
Although in all fairness, that’s not a headlamp, the thing is massive.
That’s what I would like to know as well. With the 1*8*350 tube that I have lying around the DW4 might make a nice headlight.
Is that you Hank? 
Very interested to use the DW4 as a headlamp, but as a short version. How would the 18650 tube fit in there?
Sorry, I meant the 18350 not the 16350.
Is the bezel going to be easily removable? Mostly want to know if we’ll be able to access the LEDs. Might want to try dedoming the 5700K 519a when that is available.
Welcome to the club I did it not to long ago, hence I noticed The 8 was supposed to be bold, but somehow that doesn’t work and made it stand out even more.
Judging by the indentations (?) on the inside of the bezel it looks the be screwed in, not pressed. If true that would be excellent.
Hank - is there any chance the D4V2 might be available with E17A Lime Green LEDs? I really like the E17A Azures.
The new light looks great, I’m looking forward to ordering one.
Thank you for all the work you do for us, I’m deeply grateful!
You’ve done so many things for us, much of it for free. You’re always very humble.
Thank you again!
