Emisar D4S review

Not just as far as you know. That’s the way it is implemented.

High = Pin set to output and pulled high
Low = Pin set to input and ~30…60k PullUp enabled.

Zeroflow’s description is correct. The high/low/off thing is something I stumbled upon kind of by accident back in 2014. I’m not sure it’s meant to work that way, but it works, so I’ve been using it ever since.

I noticed today that the D4S is now also offered with another emitter, XP-L HD. Has anyone tested/reviewed the D4S yet in this configuration?

And will this emitter also be offered for the D4 series?

I saw that too. So many options available now.

I think I’ll make my decision once I see some side-by-side beam shots and throw measurements. HD vs HI…hmmmm…which will I choose?

The HD they have now is going to be for wide flood. Similar to the Nichia but brighter due to the V6 flux bin. The XPL HI will outthrow it and have a more defined, yet still wide, hotspot.
It’ll be interesting to see beam shots. If you have a short but wide backyard it will light it up without penetrating. brightly, maybe 150-200 feet is my guesstimate. I have the D4S in both Nichia and a V3 HI. The Nichia doesn’t light up the darkness beyond 125 feet. The XPL HI reaches, brightly, much farther, double the distance of the Nichia. I really like the XPL HI in this quad torch, it’s a wonderful choice. The HD may gain some traction with those who don’t want the reach; it has its uses too.

Now if only they would offer it in 3000k I’d buy two more!

Good information! Thanks.

I have a question about the magnetic tailcap.

Is it just a standard tailcap with a magnet added between the spring PCB and the aluminum end cap? If so, does that mean that the added internal thickness prevents the cap from screwing on as far as it would without the magnet? How bad is the gap?

Or is the magnetic tailcap actually deeper by the thickness of the magnet, keeping the complete thread engagement but slightly lengthening the flashlight?

There is no additional gap with the magnetic tailcap. I indexed my tailcap to the head and there was just enough room to do it by sanding down the tube at both ends. Any more and the flanges at either end of the body tube would have interfered with the head and tailcap.

I doubt their are two different metal caps though, that sounds expensive for no real payoff. Instead I’d guess that there is a spacer or something used on the non-magnetic tailcaps. I’m not sure though. I only have the magnetic variety.

I have magnetic and non-magnetic tailcaps, and they are the some size. Non-magnetic is about 5g and magnetic is 10g (+/- a gramme or so). The magnetic cap has a larger font and is on the left


Speaking of magnetic tailcaps- my D4S makes a great night light.

I wan’t mine to arrive already…. :cry:

I got my Ledil Angie lenses, Bezel screws off and lenses are easily swapped out (no need to ‘operate’ on the lens legs like the D4 — this is a straight swap). Here are some beamshots. Top of light about 46cm away from my ceiling, each time brightness was set to standard one click-on level after a tail reset of power. Pics taken using my Galaxy S4 mobile phone set to auto in a dark (not pitch) room.

2285 Angie-S 15 degree, Original D4S
2286 Angie-M 24 degree
2287 Angie-M2 31 degree
2288 Angie-M 37 degree

I use the widest spread 37 degree for the D4S. I use it every morning so I don’t need to turn on room lights at 5am in the kitchen and bathroom. To my pleasant surprise I’ve found the D4S is chunky in the just the right way. It stands up very steadily, and when placed on top of a cupboard aimed at the ceiling it gives a nice amount of light when on low such that I am not yanked into full brightness while still half-asleep!

EDIT: my D4S is Neutral White – XP-L HI V2 5D, 4000K, with red aux LEDs.

Is the optics simple to change? Where are they purchasable? Some users recommended me the D4s, and I don’t get this out of my head, but I am a little afraid of optics-light as they normally do not have any defined spot. Searching for a 26650 light

Vinh put white flats in D4S. 125 kcd, 3000 lm. Nice. :slight_smile:

Optics are easy to swap on the D4S.

Just unscrew the bezel, and the flat glass piece pops out and the optics drop out. The optics have 4 legs that fit into the LED board, to keep the optics from rotating and moving.

I purchased mine from MOUSER Electronics in the UK. They had a minimum purchase before free delivery, so I also got myself a non-contact voltage detector… :slight_smile:

Very interesting! No my location is Germany, seems to be not so easy to get such an optic. But with 15 degrees a D4s would be interesting!

The 15 degree ‘2285’ optic is the standard one that came with my D4S. The ‘2855’ is stamped into the optic, so others could verify that too.

Yes same on the two I have

Interesting.

So the D4S comes with 15-degree (throwy) by default.

I usually like floody lights better (I’ve changed my D4 from the default 10622 to 10623, also purchased from Intl-Outdoor).

I don’t see other optic choices for the D4S in Intl-Outdoor though. May have to look where to purchase the 31-degree or 37-degree optic you described above (and can ship to my country at reasonable fee…)
