Looking fantastic!
Warm button leds on brass would be perfect!!!!
100% agree with this sentiment. Loving my numerous Emisar lights and the cool white switch LEDs were the main reason I didn’t buy the New Ti version. I must say, I love the idea of brass but would want the new warm white switch LEDs…
My favorite EDC lights are brass. Not only do they look great but the extra weight means I can tell they’re still in my pocket!
I wonder if the thermal performance of the brass will be okay for such a pocket rocket though? I wonder if thermal throttling happens quicker than the already quick throttling in the aluminum ones?
Any plans of a copper version ?
With a 3000k warm white led button ?
Hank can warm button light be ordered with brass?
Yes, here are some comparasion photos of the cool white VS. warm white switch back light.
the options are available for both.
Perfect!
I greet the friends of the forum; sorry if I don’t write well in English, I’m Italian and I live in Rome; therefore, 2 new versions of D4V2: D4V2TI and D4V2 BRASS; they have the same functions, the material with which they are built is different; a question: which of the two do you think is less warm at the highest level? 
Hello everybody; sorry if I don’t write well in English, but I’m Italian and I live in Rome; therefore 2 new models: Emisar D4 Brass and Emisar D4V2TI; one question: which of the two maintains the maximum level longer before going down? Hank surely knows this question well; hello and good weekend again.
Hi Riccardo, welcome the the BLF forum!
The Ti version will get hotter because the titanium blocks the heat from spreading out. The brass version will get less hot and will spread the heat better.
Wow! O.o
The warm switch and the yellow aux will look great with the brass. Was planning on getting a Fireflies Rot66 Gen 2 but I think will have to get this one first.
Can't wait for the copper version too.
I just went to the site. There is no option for extra tail cap(for brass)?
Hank, it seems to me that it would be a good idea to put on your website the option for custom orders for flashlights (D4v2). For example, I would like to order a D4v2 with a copper head, ss bezel and a black aluminum body.
Many people still write about their own whims here.
Excellent idea ^^^^^
Not all of the parts are interchangeable.
For example: My titanium tailcap does not fit on any of the aluminum body tubes. Also the aluminum body tubes do not fit on the D4V2Ti’s copper head.
Is the difference in threads caused by the material from which these parts are made?
If so, then universal threads could definitely be made.
I agree
I think the Ti and Cu threads just aren’t cut quite as deep as the Al threads.
The titanium body tube works with the aluminum head and tailcap, but the reverse isn’t true. I can’t use the copper head or Titanium tailcap with an Al body tube.
Lovely, thank you for the warm switch LED option! Had I not just ordered a Noctigon K1 (dark grey, W1), I probably would have gotten the brass D4V2 first. There is no question that I’ll be ordering one of these brass beauties in the future (warm switch LED, raised switch ring, SST20 4000K), probably after Christmas. Hopefully not a limited edition light?
[Edit and off-topic] Now… I only wish Hank would introduce a headlamp (in aluminum though, since brass might be a tad heavy on the head!), with Anduril of course, a super-low “Zebralight level” of sub-lumen moonlight mode and a high-CRI option. Then again, depending on brightness levels, maybe a warm switch LED could be used for a super low floody moonlight mode - just rotate headlamp body 90 degrees to point the switch forward! I generally quite like my 4000K-ish ArmyTek Tiara Pro, which has a nice smooth and wide beam spread, but after having numerous Emisar lights now, I am totally spoiled by the superb UI that ToyKeeper has come up with and find that I’m somewhat annoyed when using any other light! To satisfy both those who prefer headlamps with tighter beams and those who like smoother, floody beams (I do), maybe an optional screw-on diffuser could be supplied on a reflector based headlamp? Or I suppose an optic-swap system like the current D4 lights have could work too and might be more efficient than adding a diffuser? Oh and sorry, if there was already an Emisar headlamp request thread, I didn’t find it…
I would buy this. I almost don’t care how he designs it… I’m sure I’d like it.
