Emisar D4S review

I think only int outdoors has the magnet option.

Anyone know if Mtnelectronics would swap in some LH351D’s for an added fee? Really want to order one of these but would prefer it with those LEDs.

Is it safe, or rather unsafe, to say that this will get nuclear hot like the D4?

I don’t think so.

ios v1 was developed by Tom E. but he ran out of time because of his day job.
So Toykeeper was asked to finish v1 to the specs from Emisar.
Later she added stuff to it and that became v2.
V3 has a completely different code base and uses stuff from Andúril. It is hard find a feature that’s not in it.
I am shure Hank from Emisar choosed what he want his light.

But if you want more features you can flash Andúril on all Emisar lights.

I’m guessing this should run alot cooler than the D4 given that it is the same quad but far more mass for heat dissipation. I was actually hoping for a 7 emitter 26650. sigh.

I just ordered the XP-L HI 5D with magnet.

Nice. Which color did you order?? I personally think smooth gray looks awesome because I have one gray d4.
Smooth gray looks rich.

I ordered the smooth gray too because that one is my favorite. I have pretty much all the Emisar colors already. The smooth green on my D1 looked great too but the gray looks more serious.

That is a pretty reasonable answer. I had a 50$ gift card and well, as soon as i get back home there it goes, just wish it was a little more since that magnetic tailback looked sweet. Or i could just order with a normal credit card and buy more lights with the gift one :slight_smile:

Ok ok i’m buying it.
Is the best battery choice still the shockly (?) Black wrapper 26650 30A discharge cell or are there better alternatives right now? I found 2 on gearbest for 6$ each so pretty decent…

Yes, go with the shockly.
And the price is good. I ordered three in a GB for 5,5€ a piece, with shipping they came nearly 7€

Hi I wanted to order the same Shockli battery’s which site did you use? Are the button tops or flat tops?

Thsbks

Just received a reply from Mtn Electronics.

Pre orders will come with magnetic tail cap and plain caps will be available at a later date.

I don’t think any more changes are planned. And it has spring-side flashing access so it can be firmware-upgraded a lot more easily than the original D4 if desired.

The stock UI is still pretty similar to earlier Emisar products, but I managed to sneak in some extras copied over from Anduril. Mainly, the additional ramping features and ramping config options. So it has both smooth and stepped ramps, and they’re configurable. It was less work and less risk to keep all that than to remove the extra features. But the blinkies are mostly still the same (ish) as RampingIOS V2.

The only potential firmware issues I’m aware of are:

  • Changing the aux LED mode is 7 clicks in “off” mode but 3 clicks in “lockout” mode. I offered to change it to make them both the same, but Hank didn’t think it was worthwhile. So there’s a minor UI inconsistency.
  • I’m not sure if the production units will remember the ramp level when changing the aux LED setting for “off” mode. There was a bug fixed for that late in the process, and I’m not sure if it was fixed in time for production. So… there’s a chance it might reset to default brightness after changing the aux LED mode. This remains unknown though. (update: production units use the fixed version)

I should probably get the code merged into the main repository now that the light has gone up for ordering. I still have only limited time though, so I’m not sure when exactly that’ll happen.

It can probably still start fires, but not as easily. There are a bunch of physical and firmware changes which make it less of a fire hazard, but you should still keep it locked while carrying it.

Which 26650 is the best for the d4s? Shockli or litokala ?

Gray Nichia ordered… :smiley:
I’ll certainly get a XPL one too… :person_facepalming:

From the pictures the circuit board looks screwed in not glued in like the D4. Do they make a 26350 size battery? That would be cool. The ui or whatever it is called is really neat. It would take a while just to learn that.

pat, the difference between those 2 cells is negligible so either one you find should do the trick. You almost assuredly couldn’t tell the difference between them with your bare eyes. The Shockli has a bit more capacity, so given that it may have an edge. Still, it’s a close call either way.

The UI updates sound nice enough I think Hank should have it implemented in the rest of the Emisar family going forward.

I haven’t really tested it much, but RampingIOS V3 already supports the same set of build targets that Anduril supports, so it should, in theory, run fine on all the other Emisar lights.

Would 4 XPL HIs or 4 XPG2s be better for running a hypothetical sustained output around 1000 lumens? Would there be any heat issues with the host and how long would the 26650 last?
