I would love na upgraded D4 with aux lights or a viable route to modify my D4.
The D4 hast just the perfect size for EDC and with 4 Samsung LD351 it surely has enough punch to impress ppl.
You can always buy an aux LED board from Lexel, though it would be always on because it’s hardwired to the battery.
I’ve found LD351 to be too floody in my D4.
I find the SST20 much impressive even if they give less lumens (but more cd…)
Take a Convoy L6 and put it in the Emisar shrink machine.
Emisar D6
2s 18650 driving a 6V LED with an optional tube for 2s 18350.
Emisar D6s
As above but with quad emitters.
I don't know, but at least in my mind, that doesn't really fit into the line of lights Hank made before. There must be something novel and/or smaller, not just a clone of the Convoy L6.
And here I am just thinking a D4S thrower could be an interesting option…
Emisar’s naming convention seems to use the quantity of emitters as the number in the model. A 4-emitter thrower could be huge. I’m guessing you mean is a 26650-powered thrower? I don’t know what that would be called. Maybe a D1SX? (D1S with eXtra battery capacity)
That idea strikes me as something that would sell well.
What a great wife! 
I remember 7 years ago, i was experimenting with such things with my “DRY” triple XM-L. Even used iced in the water and dry ice, external power supply with variable current/voltage.
I envy those of you who can use your lights in a winter climate. We have 30-31 deg C @ 8pm nights here. 
I envy your husband 
Hi Elena! It’s me, your other husband!
Sorry my post wasn’t clear. I wasn’t thinking of an L6 clone. L6 is too big. Emisar is about getting as much light as possible from a small package.
Shrink the L6. Get rid of the tail switch. Use an Emisar style driver with a ramping UI.
Power comes from 2 18350 in series or 2 18650 in series. The light would use one or more 6V emitters. I don’t know if this can work.
It’s all about works in progress A_D, more than one company is working diligently to bring us what we ask, but they’re in line at the factory… we must wait. Really that simple. It is what it is…
I agree.
I am happy to wait and see what Hank brings us next.
Delighted with the D4S.
I was really intrigued and delighted with the 7x XP-G2 DQG and found it to be an excellent foray into the multi-emitter market, keeping in mind too that they do trend towards minimalist design. Ultimately though I discovered that the driver output so closely matched a Cree COB in high CRI that I made some up-top changes and now have an excellent camera light for macro photography that is capable of 2004 lumens with zero artifacts and zero hot spot/beam disturbance. Love it in this mode! I affixed Velcro to my lens hood and can easily strap the DQG COB light onto the hood so the source is directly in front of my subject, works so well I have thought about acquiring two more to make an array of 3 lights around my macro lens for the ultimate in macro lighting.
Edit: The finish and knurling on the 7x DQG is top notch, my favorite factory knurling of any light I’ve seen, bar none…
And in the COB mule configuration, priceless to me…
Paired with my hybrid 100mm Macro IS lens on the Canon 5D Mk IV, images like this are just exceptional…
Wait there is more… fireflies rot 66.
My D4S arrived today
Nice !
I don’t think I’ll buy it, because I know it would be a shelf queen, but if I had to I would chose red Aux LEDs too !
Anyone has an amber Aux to show?
I am really torn between cyan and amber. Cyan looks so cool, amber looks so comfy…
I’m interested in this aswell. Does anyone know if Mtn. Electronics will be carrying the other color Aux leds?
I did not realize that the Gen-1 D4 was more powerful than the current version. Was there a reason for changing the driver to the “less powerful” version?
