TK's Emisar D4V2 review

Emisar D4 (V2)

This is the updated 2019 version of the Emisar D4, produced by Hank Wang of Intl-Outdoor.

Disclaimer: I helped make this. I’m not an impartial reviewer. This thread is primarily intended to answer everyone’s questions about this brand new product.

I reviewed the original Emisar D4 too, if you’d like more pictures, information, and background context about this light.

What’s New?

If you’re already familiar with the original D4 and just want to know what changed, here’s a quick run-down.

Compared to the original D4 with RampingIOS, the new D4V2 is updated in these ways…

  • Added an optional steel bezel
  • Added an optional tailcap magnet
  • Added a tailcap lanyard attachment point
  • More grip on the battery tube
  • Different host colors available
  • More LED types and tints available
  • MCPCB is screwed down now
  • Larger MCPCB with dedicated screws holes, so the 4 optic legs are in intact in the D4V2
  • Rotated the LEDs for a smoother beam
  • Added aux LEDs with 7 configurable colors plus rainbow and voltage modes
  • Upgraded the driver to use a new MCU with more pins and twice as much space
  • Added spring-side firmware flashing pads to the driver, for easier updates
  • Fixed reverse polarity protection
  • Completely new firmware — Anduril instead of RampingIOS… so it has a lot more modes and options. More details on this below, since it’s too much to cover in this quick summary.

So it’s more or less the same D4 people have loved for the last two years… only better.

Interface

TL;DR: Click for on/off, hold to change brightness. That’s all you really need to know to use this UI.

Beyond that, the user interface (UI) has … a lot of features / functions. There’s a good chance that, if you want a specific thing, there’s probably a way to do it. I’d suggest reading the manual for general info about how it works, or referring to the UI diagram below. Or both.

If it helps, here’s a partial list of what changed in the UI between the original D4 and D4V2:

  • Instead of just smooth ramping, there is also a stepped ramp with discrete levels… and switching between the two is quick and easy
  • Both ramps have configurable floor and ceiling levels, and the user can choose how many steps in the stepped ramp
  • Made ramp direction predictable, and added a shortcut to ramp down
  • Added an option to choose between automatic or manual memory to choose the brightness at single-click from off (automatic uses the last-ramped level, manual uses a level the user explicitly configured)
  • Made moon mode lower, and dramatically increased moon mode runtime
  • Added more modes behind the battery check mode: Sunset, Beacon, and Temperature Check
  • Moved Lockout mode from 6 clicks to 4 clicks for faster access
  • Made Lockout mode double as a momentary moon mode with 2 levels of output, so it doesn’t need to be unlocked for quick tasks
  • Made confirmation blinks much faster
  • Added a “Muggle Mode” on 6 clicks, to make the light safe when lending it to other people (is limited to only safe levels, and all other modes are inaccessible)
  • Moved Beacon mode into the battcheck mode group, and made its blink shorter
  • Made Beacon Mode’s timing and brightness configurable
  • Much smoother thermal regulation
  • Changed thermal config from “hold until hot” to a sensor calibration step plus an explicit temperature the user can enter precisely
  • Added support for colorful aux LEDs
  • Added an entire group of strobe / ambient modes: adjustable Party Strobe, adjustable Tactical Strobe, adjustable Bike Flasher, Lightning Storm mode, and adjustable Candle Mode with configurable self-shutoff timer
  • Made Momentary Mode brightness configurable
  • Made Momentary Mode work with strobe-group modes too, for momentary strobes (good for light painting)

The new firmware is a complete from-scratch rewrite, but the basic usage is the same: Click for on/off, hold to change brightness. That’s all you really need to know to use it.

Aux LEDs

The aux LEDs turn on during the “off” and “lockout” modes. They are off in other modes, like when the main LEDs are on.

This animation shows frames from a video while the light is in “rainbow” mode:

The rainbow mode looks exactly like this animation; it doesn’t fade between colors because that would require keeping the MCU awake, and that would greatly reduce the standby time.

The aux LEDs have four brightness levels (modes) and nine colors.

Brightness levels / modes:

  • Off
  • Low
  • High
  • Blinking (1 Hz low/high pattern)

Colors:

  • Red
  • Yellow
  • Green
  • Cyan
  • Blue
  • Purple
  • White (ish)
  • Rainbow animation
  • Voltage (blue = good charge, green = medium charge, red = low battery, off = critical battery)

These can be configured independently for the “off” mode and the “lockout” mode, so the user can tell at a glance whether the light is locked or just off.

To change the aux LED brightness level / mode:

  • In “off” mode: Click 7 times.
  • In “lockout” mode: Click 3 times.

To change the aux LED color:

  • In “off” mode: Click 7 times, and hold the last click until the desired color is reached.
  • In “lockout” mode: Click 3 times, and hold the last click until the desired color is reached.

The modes and colors are in the order shown above. Rainbow mode is indicated by cycling colors, while voltage mode is indicated by faster cycling colors.

Here’s how the MCPCB and aux LED board look. My sample has different resistors than the production version, but it should otherwise be the same.


I tried to measure aux LED power use. I can’t say for sure my numbers are good, since my D4v2 has the resistors set up differently than a production model, and my measuring equipment isn’t very precise at low power levels, but here’s what I got…

  • Low mode (rainbow): 0.077 mA to 0.107 mA, depending on how I measure
    Runtime: 3.7 to 5.2 years
  • High mode (rainbow): 2.89 to 3.01 mA, depending on how I measure
    Runtime: 48 to 50 days
  • Blinky mode (rainbow): 0.205 to 0.424 mA, depending on how I measure
    Runtime: 0.9 to 1.9 years

For comparison, here’s moon mode, the bottom of the ramp:

  • Moon mode: ~1.8 mA
    Runtime: ~81 days

These were each sampled over time and then averaged. The power source was set at 3.7V. Runtimes assume a 3500 mAh cell.

Packaging

The light comes in the same packaging as other Emisar lights, which is simple but very effective at keeping the light safe during shipping. It’s a cardboard box which is heavily padded inside. It could probably fall off a plane and not cause any harm to the light inside.

I … kinda forgot to take pictures of the packaging, but it looks identical to the original D4 packaging except it says D4V2 on it. Here’s how that looked in 2017:

Comparison to other lights

Emisar D4 (original) vs Emisar D4V2:

Emisar D18 vs Emisar D4v2:

Host, Components, and Build Quality

The D4V2 has an O-ring and square-cut threads on both ends. The battery tube has a square knurling pattern for grip, and recessed grooves for attaching a clip. The tailcap has grip ridges and a lanyard attachment point.


The button still sticks out like the original D4, which makes it easy to press.

The lanyard hole’s edges are chamfered to make sure it won’t cut through the lanyard string:

The driver has pads for flashing firmware, which makes it really easy to update… if you have a pogo pin adapter. Without the adapter though, it’s nigh-impossible because the attiny1634 MCU doesn’t fit a SOIC8 clip.

I would not recommend trying to remove the driver. It’s glued like the original D4, but more importantly, it has a lot of wires! Here’s how the top side looks in my early prototype, with its brain hanging out:

Tailcap Magnet

There’s a magnet in the tailcap, if you want one. It sticks to stuff. For example, a door clasp:

… or a coated wire shelf:

… or even a single screw hanging from a vibrating ceiling fan:

The magnet is not as strong as the D4S magnet. It’s not quite as “friendly”, so to speak. But it’ll still stick to pretty much anything solid and ferrous.

Beamshots, Output, and Runtime

… eventually! Wink

(sorry, trying to post this review quickly to answer people’s questions… and the questions aren’t about the beam… because people mostly already know what the beam and runtime are like)

Default configuration:

  • Ramp segments:
    • Level 1 to 65: AMC7135 chip only
    • Level 66 to 149: AMC7135 + FET
    • Level 150: FET only
  • Smooth ramp: 1 to 120
  • Stepped ramp: 10 to 120 in 7 steps: 10, 28, 46, 65, 83, 101, 120

Thermal regulation

Compared to the original D4, the thermal regulation is much smoother. It’s mostly not noticeable when it makes an adjustment during use. It’s also far less prone to jumping around, so when it finds an optimal level it pretty much just stays there. Here’s how it looked during the first 10 minutes in a recent test:

The numbers on this graph are very approximate. I don’t know what the actual peak output was; just the relative brightness throughout the test. I scaled the graph according to the official specs, minus an arbitrary correction factor since my battery is getting a bit old so it’s not as bright as it would be with a fresh cell.

Source Code

… will be released soon. I’ve been a bit busy.

This light runs Anduril, and is thus supported by the FSM UI toolkit. That means it’s pretty easy to run other interfaces if desired. If you can describe your desired interface in the form of a flowchart, you can probably make it run on the D4V2.

Potential Issues

First off… THIS LIGHT CAN START FIRES. You have been warned. Be careful. Lock the light while carrying it.

The second potential issue also relates to heat. Thermal regulation is difficult on such a hot light, so it may exceed the configured temperature limit for a little while when turbo is activated. Over time it settles back to a comfortable temperature, but in turbo mode it can get very hot in just a few seconds.

With the aux LEDs on high mode, I don’t know how much power is used on the production version. I couldn’t measure that, since my sample has different resistors and thus different aux LED power use.

The clip is a clip-on type, not a screw-on or ring-in type. So it may scratch the anodizing around the clip attachment point.

Upgrade / Mod Options

The most obvious ways to modify this light are:

  • Change the optic. It uses a standard type, so you can swap in other compatible optics.
  • Change the emitters / MCPCB. Intl-Outdoor and MtnElectronics both sell compatible parts, though only the Intl-Outdoor boards will screw down.
  • Glow tape or tritium vials could be added, but it may be redundant due to the aux LEDs.
  • Firmware changes. This is easy to do if you have a pogo pin adapter, but difficult otherwise.

Most of the changes people would be likely to make are available as options while ordering. For example, a clip, a tailcap magnet, different emitter types, and different optics.

Summary

What I liked:

  • … phew. Almost everything, really. This light sets the standard for what a pocket rocket can be.
  • The steel bezel is a nice upgrade.
  • The clip is much better than the original D4 (which had none, and then had a kinda bad one, and then finally got a decent clip) (D4V2 uses the finally-decent version).
  • Basically all the upgrades are very welcome improvements to the tried-and-true D4.
  • I particularly like the firmware flashing pads, but I may be part of a pretty small population who cares about that.
  • Many choices of emitter type and tint, to suit almost anyone’s taste.
  • It ships with a full-featured version of the latest Anduril.
  • Emisar laid new foundations for the next generation of flashlights, and that makes things better for all of us — even those who don’t actually buy the D4V2. When new tech shows up in other lights, it’s likely because of the work Emisar did.

Things I feel neutral about:

  • Side switch still sticks out.
  • The knurling feels a bit aggressive.
  • Higher regulated modes would have been nice, but it’s not really a big deal.

What I didn’t like:

  • I’m not a big fan of the sand/gold/tan color.
  • On turbo, it gets hot very fast!

The End

Or an end, anyway.

(reserved for what, you ask?)

(I don’t know yet)

(so for now, it’s reserved to make me feel better about having a place set aside for … whatever … maybe … in the future)

Ohh that TIR board is extremely nice! Top work on that and finally adding some pogo pins for easy updating of the D4. Pretty excited to get one myself!

Just for clarification, do the rotating aux colors fade between changes or is it an immediate change just like in the animation?

Just like the animation. All I did was convert a video to a GIF.

Thank you for this excellent review but also for the work you put in to create this light.
I am huge budget light fan, so 45 is not something I would ever pay for a flashlight. But who knows, I might go for it for Christmas Wink

Many thanks also to Hank and all vendors for making this happen.

edit:
Just to clarify: I am not saying that the price is not worth it, it really is! my cutoff for lights is just 20-30 max.
This product is very, very nice.

Thanks for the review, it has all the information that one could wish Smile Thumbs Up

Those are all nice upgrades, yet the ultimate problem of the D4 was not solved: D4V2 having the same switch as the D4 makes this ultimate pocket EDC light again unsuitable to pocket EDC Sad Flat Stare Tired . It will switch on in your pocket, you are obliged to lock it out which, however nice the user interface is, makes the handling medieval compared to my ancient EDC-tailclicky. If I need light, without looking or fiddling I have light in 1 second, when I’m done its back in my pocket in 1 second. That is how I have used my EDC for 8 years now (many times a day) and I see no reason to give that up for all the bells and whistles in the world.

Waiting for D4V3 Flat Stare

Edit: maybe I’m particularly grumpy about how I want my EDC to be, see the above as a personal disappointment.

Thanks for the review! Really nice light. Already ordered mine Big Smile

What clip do you use on the green D4? This one looks pretty nice. Will it fit on the V2?

Yeah… I personally plan on never getting a soldering iron near this light. I don’t want to deal with soldering such small things in a tight space.

It’s a SolarForce L2 clip with some material removed to make it fit. It’s not great, but it works if I add a paperclip inside the tailcap.

If the Emisar clip had been available at the time, I probably would have used it instead.

This looks absolutely awesome. I have ordered one in exactly the same colour scheme as this one, and I can’t wait for it to arrive!

I love how solidly-made my D4S feels, and this I am sure will be no different.

Do you happen to have picture of the clip TK?.. Not sure If you’re referring to the one that ships with the V1 or a new design. Kindly correct me if I misunderstood. Thanks for the review!

Great job Toykeeper, a lot of questions and worries I had have been answered.

Quote:
Side switch still sticks out. The knurling feels a bit aggressive.

That’s actually good when using the light with (winter) gloves and/or in wet conditions. I sold my FF ROT66 literally only because I couldn’t operate the switch even in thin winter gloves.

It’s only a bit sad the D4 is no longer the ultimate lumen-$ ratio light with a UI that’s easy and accesible for everyone, not only for flashlight nerds. I used to recommend this light among urban explorers as the best addition to a headlamp, but I don’t know whether I’ll still can do that.

Besides, It would be useful Anduril would have true memory mode, not the selective MM it has currently and is very confusing.

btw, does unscrewing the tailcap result in the light resetting to 1×7135 mode ad in the V1?

good tint: Nichia E21A 2000K-7500K except d240 bin, Nichia 219B sw40/sw45, 219C sw303, Cree XPL-HI A/D bins, XHP70.2 5A, Samsung shaved LH351D's, SST-20 FD2, FA3, HA3, .

The D4V2 clip is the same as the most recent D4V1 clip. It’s the one shown on Intl-Outdoor.

The D4 originally had no clip at all though, which is why I modified a SF L2 clip to fit. It took a while before Hank found a decent clip which fit the D4.

It has two styles of mode memory now… automatic and manual:

In automatic memory mode (default), this is how it works:

  • 1 click from off: return to the last level the user ramped to
  • Loosen/tighten tailcap, click: go to 1×7135 brightness (~140 lm)

In manual memory mode, the user can select a specific brightness and then always start at that level. Ramp to the level you want to memorize, then click 5 times to save it. Afterward, this is how it works:

  • 1 click from off: go to the memorized level
  • Loosen/tighten tailcap, click: go to the memorized level
  • 5 clicks while on (but hold the last click for a moment): go back to automatic memory

Basically… automatic memorizes the level every time the user does a ramp action, but forgets during a battery change. Manual memorizes the level only when explicitly told to, and it still remembers after a battery change.

I’m not sure what “true memory” means though. Is it one of the two methods described here?

There is also a way to make it memorize several levels. The stepped ramp has a configurable floor, ceiling, and number of steps. So if you want a reliable way to get to a certain level (or a few), adjust those values to produce the desired steps. If exact values are needed, there’s a tool in the firmware repository called “steps.py” which helps with this process.

Question, can I configure things as follows.

2 regular modes, with the light always defaulting to a certain one.

1 special mode that’s activated by a longpress when switching the light on.
Often that’s turbo but I could imagine it to be moonlight when used as bedside light.

Chargers: 1xBasen BD01 5/5, 1x Gyrfalcon All-88, LiitoKala: 3x100 4/5, 2x202 5/5, 1x402 3/5., MiBoxer C4-12 3/5.
Flashlights: BLF Q8 4/5, DQG Tiny III 26650 5/5, FiTorch MR35 3/5, Haikelite SC26 HD 3/5, Lumintop Tool AA/AAA 4/5, Nitecore LA10, Sofirn C01 BLF 3200k/5600k, Zebralight H600Fc 3/5.
Powerbanks: EasyAcc 26800 mAh 3/5, Xtar PB2 4/5.
Waiting for: (DQG Tiny) 21700 EDCs. Xtar powerbank that (also) takes 20700, 21700, 26650

Ordered a sand one with XP-L HI 5D and all the accessories as soon as I saw that the product page was live. Not cheap. I can’t think of any other light that I have ever been able to buy so quickly without any guilt. Not even the FW3C, though it’s a close second to the D4V2 in terms of how much I wanted it.

I think subconsciously, the reason I got a sand D4V2 with SS bezel is to give me a reason to buy a matching D18 down the line…

The prescence of green or cyan would have made it a hard choice however. I’ve already got a green D4S just waiting to be paired with something.

Do you happen to have picture of the clip TK?.. Not sure If you’re referring to the one that ships with the V1 or a new design. Kindly correct me if I misunderstood. Thanks for the review!

The D4V2 clip is the same as the most recent D4V1 clip. It’s the one shown on Intl-Outdoor.

The D4 originally had no clip at all though, which is why I modified a SF L2 clip to fit. It took a while before Hank found a decent clip which fit the D4.

Thanks TK! I thought there was a new design vs the most recent clip in the D4V1.

You might want to read the interface section of this review for details on how the UI works.

Or perhaps click the Link in my signature for information about making and flashing firmware, if you want more extensive customizations. That’s an option too.

Is it easy to put in a FW3A style button that doesn’t stick out?

Ok, thanks. I’ll just wait for a light with another UI.

Man I keep telling myself I dont need one of these after acquiring two D4s with Anduril in the last month, but between the new aux lights and the other ergonomic enhancements im having a hard time holding that feeling off.

If you want the light to default to a specific brightness with 1 click from off, it can do that.

If you want it to also have a shortcut to moon or some other low level with a hold from off, it can do that.

It also has a shortcut to a user-configured high level, using 2 clicks from off.

… and a bunch of other stuff. There are a lot of modes and options, and the question above makes it sound like you’re unfamiliar with it… so I recommend looking at the online manual to learn more.

Brands like Emisar restore my faith in Chinese products. He has made everything better without cutting any corners. And for a very reasonable price considering all the improvements.
I will buy one for sure, although probably closer to xmas.

Hank included a picture of the D4V2 with a clip on his page. As TK said, it’s the same clip that is offered with the D4V1.

So can I now set a fixed level for one click on? Say always at the top regulated level.
