Emisar D4S review

FWIW, you can assign the brightness level for lockout mode. It uses the current ramp’s floor value. But it doesn’t have a way to make lockout not light up at all when the button is pressed.

Momentary mode is meant to be usable for signalling, so that absolutely any pattern of button presses can be sent as a signal. That’s not really compatible with having an embedded config mode. However, I have a note in the sources to maybe figure out a way to make the strobe modes work in a momentary fashion. I don’t have a good solution for that yet though. Perhaps it’d be something like 5 clicks for momentary, or hold the 5th click for momentary strobe. And use whatever strobe was last accessed.

So… the idea is at least written down for later use.

Alex, keep in mind that the ramping IOS is Hank at Intl-Outdoor’s baby… while TK may have been instrumental in it’s reality it was Hank that decided how his light would perform.

Talk to Hank about the implementations you’d like to see in his lights or reflash the MCU to your own coding. :wink:

Thanks, it was just an idea I wanted to share…

I also found a nice silicone diffuser for this light in case someone is looking for one, this one fits nicely

Is the 36mm size from this link

And here is a picture of it installed

I´m newbie @BLF and need some advice before i finally order the (Green) D4s with Green leds.

I know Hank have red and amber also, but i think that the Green will be more useful as "moonlight"

I´m going for the new Added XP-L HD V6 options on Nov, 9, more lumens, more flood/less throw.

Q should i chose the 6500 or 5000? Also need to know a little more about the heat. Less is safer.

I need flood more than throw, also appreciate the option to reflash the D4s with future firmwares.

Greetings from Sweden! Any memberadvice regarding the Led and tint?

Welcome! In general, I think that’s more useful to find the light in the dark than as a moonlight. Also, to be honest, moonlight is lower than the high-mode of the Aux-LEDs.

If you have no preference, go for 5000K. Heat should not be a huge difference between those two. There is more difference between different LED types (Nichia 219C, XP-G3, XP-L)

Regarding flashing: This is currently the easiest light to flash a new firmware to. There are 2 different connector styles (2x3 and 1x6) out there, but they are easy to use if you can solder.
Most importantly: You don’t have to disassemble the head.

Thank you zeroflow for welcoming me here.

Ok, your reply will give me the guidelines i need.

Amber was my first choice, and if moonlightmode is lover than the leds i might change my ming and go for Amber.

I can imagine that amber looks like glow (old bulb) in the dark, and strong enough to find the D4s in a dark room.

As a visual impaired user that function is very much appreciated, and will not drain the battery if it´s always ON

So, XP-L HD 5000K and Amber might be my choice after reading your advise.

Do you know if it is the Blue or Black version of 26650 here? https://intl-outdoor.com/emisar-d4s-26650-high-power-led-flashlight-p-932.html

Cyan makes a great moonlight.

Thank you Texas Toasted.

I´m shure it is very good, but i´m one of them that hate blue leds, in car stereos and everywhere.

I´m an old tech radionerd från 1958, and really prefer the amber and orange (my favorite colour)

The green leds looks cool in a green flashlight, so it will be green or the amber. Have too Google.

Or wait for more reply´s here :)

I can see the amber looking great in the green light, the green and gold of legend. :slight_smile:

Welcome to insanity grand central, be forewarned that flashaholism is an addiction that gobbles up plastic and all the cash in your wallet at amazing speeds! :slight_smile:

If you don’t like blue LED’s, then stay at 5000K or below. By 5700K the light is a bluish-white in appearance and above 6000K it’s very very noticeable. Many here like below 4000K, but that will be entirely up to you of course. You might find the lower Kelvin temperatures easier on your eyes.

If you can get Anduril flashed to your D4S it is easy to set the ceiling in Anduril so you can avoid heat issues with a simple lowered ceiling in the ramp. A double click to Turbo easily allows full use of the light when needed. Anduril also allows more complete thermal control through the firmware. AND it adds a candlelight mode and lightning mode that you would love to use, especially if you go with a warmer white tint to begin with. Candlelight flickers like a candle, you can set the brightness level easily and you can also set a 30 minute timer to turn it off, or double it to an hour… pretty neat having an electric candle…

Thank you DB Custom.

That was the information needed to finish my order, also mailed Hank about firmwares.

I have to solve that later on, i know how to soldering but at this time not how to update it.

Will have to search BLF for that, but i´m shure that i will try other firmwares 2018/2019

Crazy spending: I know exactly, have done the same with "needed" vapestuff since 2015

Happy to have been able to help. You’re going to love your new flashlight, it’s an awesome smallish handful… :wink:

I know you’re new here so please just remember, ToyKeeper is the light of this forum, always look to her and you’ll never go wrong. That’s the pure and simple of it, right there.

Indeed! :wink: So Eloquently put my good man! :+1:

I bought this light several months ago, and it seemed that I had pretty much found the Holy Grail of flashlights (at least for my main purpose, daily dog walks).

Unfortunately it started flickering pretty badly about a week or two ago - mainly just after turning it on, or after changing the brightness level. There is also considerable stuttering when I try ramping. Sometimes it won’t ramp at all, or it will just jump from one level to the other instead of ramping smoothly, and it will also flicker on those occasions. It seems to be getting worse, and I am worried that it will soon become unusable.

Is there any remedy for this? Apologies if this has been asked before, as I have not got the time to read through all the comments on this post.

Flickering is almost always a ground issue. Make sure any retaining rings are snugged down and that all contacts are clean.

There is a known bug with the switch in firmware when the presses have bouncing or something simmilar.

It may sound strange, but is there a possibility, that you do not press the button “properly”? For example, the bug mentioned before can only be reproduced by hand by pushing the button “strange” e.g. from an angle and very soft.
In that case, the light registers multiple button presses where it triggers a different action than expected.

Just FYI, but cyan is not blue, although between most cameras’ poor white balance settings and possibly your computer/phone monitor’s color profile miscalibration, it may appear blueish in the photos.

> flickering

Besides making sure everything that should be tight is tight and all the threads are clean, consider putting a dab of conductive gel on the theads and on the tip and base of the battery.

Sometimes the springs may be making intermittent contact if the metal was cut at an angle, so make sure that contact is smooth and meets the battery at a broad flat position, not at a knife edge or pinpoint.

Cyan is halfway between green and blue on the color wheel. It’s primarily seen as a blue family and is a key ink cartridge in many printers. It is a mix of half green and half blue, but that makes it 75% blue as green itself is a blend of blue and yellow. :wink:

Thank you DB Custom.

Yes, i will have an eye to look for ToyKeepers posts, also have to search this forum to learn more.

Have been here many times before, ended up with an account to make questions possible for me.

Very fast response i must say, that response was mucho needed to awoid mistakes with my order.

To be, continued.

Nothing has changed in the way that I press the button, but I will follow the suggestions and report back. Thanks.

EDIT:

That was easier than expected - everything working nicely now, and I can no longer reproduce the flickering. Thanks for the advice - it really is a fantastic light, and I couldn’t wish for more (I’ve got the XPL-Hi version in NW).
