TK's Emisar D4 review

The LH351D 4000k 90CRI version is yellowish on the verge of green. It does get better at higher brightness but still not nice like the 219B 4000k. The two groupbuys for the LH351D used the T7 and T6 bin. If we can somehow get our hands on the T3 or T4 bin would be ideal for the FW3A.

I still think a throwy light like the Haikelite SC26 XHP35-HI NW or Lumintop GT Mini would work well for your purpose.

@DBCustom, you do know there’s a Nichia 219C version of the MF01, right?

I see green at low levels it seems… so it would be normal for this LEDs, and not due to optics then ?
I guess I’ll have to try the 3000K SST20 95CRI in my D4 when they’ll be there…

My 219c 5000k is from December. It has some green from moon to 1x7135 (only if you see it in comparison with other white/rosy tints on a white wall) from around there and up to turbo is a nice white.

Just received my silver/white D4 directly from Hank. Took 17 days from day of order . My first Emisar and loving it. The more I use side switch lights the more I think they will be the only type I buy from now on , especially with ramping. The UI is perfect and the thermal step down works flawlessly. Being able to get momentary on is also a plus. Tonight I get to put it through it’s paces if it would stop raining every single day. Emisars are actually more attractive than pictures do them credit. I see more in my future. :smiley:

The HVAC pics are a tough situation. Needs to be small for insertion and control, yet needs to make enough light for a demanding job, while not getting hot or stepping down. Most of the lights that can produce enough light to do this will step down in short order, or are too large for the situation. So I’m thinking the D4, the new D4S, or the DQG Tiny 7 XP-G2 lights are probably more inline with this odd situation. The new D4S will have the large cell and some programability, the DQG might get too warm and at higher levels will step down, maybe too soon. The D4 at the necessary power levels will probably get too hot.

An Raysoon F13 modified triple with CUTE-3 also uses the 26650, can be fit with a nice heat sink, would offer output and run time with program options through firmware selection, but of course this would be a build and not a readily available light.

Mateminco has a triple X6 coming out, quite floody, makes around 3000 lumens, can run quite long in the 6th of 7 levels without getting too hot, might be a likely candidate as well. Run time would be more limited due to the smaller cell size (18650)

Sofirn C8F triple? Decent price, not too large, in the 3000 lumens vicinity. Tends to be more throwy than the Mateminco X6 at similar output levels, both use the 18650 cell.

Emisar D4S
Sofirn C8F
Mateminco X6 triple

Check those out Zamar and see what you think, none of them should be extremely pricey, all are worthy fairly high powered lights. The Mateminco might not be available just yet…

Thanks again. What battery makes & models do you recommend for these flashlights? Are they sold anywhere on cheap? Some 50mm diameter flashlights I seen require 4x18650 batteries. Are these any better for my purpose than 1x18650 flashlights above, and which models?

Hello,
I have Emisar D4 and I have a question.

I took a photo of the reflector on lowest light settings and it looks like this. There are some scratches (marked green) and something that looks like dust specks (marked red)

I wonder mostly about the scratches, how did they get there and is this normal? And I know it is just a tiny detail, it doesn’t bother me too much…

Also my temperature readout is way off, showing 15 degrees more. But I’ve read I’m not the only one here :slight_smile:

As far as scratches goes I can’t help. As tar as the temperature setting goes you likely need to recalibrate. From page 1 of the thread,

10+ fast clicks then press and hold: Thermal config mode, added in v2. Hold the button until it gets to the action you want:
Blinks out current temperature limit. Release button to exit with no changes, or keep holding to continue.
“Buzzes” for 2 seconds. Release button to set temperature limit to maximum, or keep holding to continue.
Light goes to turbo. Hold button until the light feels hot enough, then let go to set a new temperature limit.

If you are adventurous you can put we firmware like Anduril

Yes, I’ve had it recalibrated already. Its now set at 65 and given the limit is 70, there is not much leeway left for higher settings. It would be nice if there would be higher limit. Or a more precise temp sensor.

I’m adventurous but I know myself - once I disasseble something its never the same again… :smiley: And not in a good way :frowning:

I don’t believe ( others may correct me) but I don’t think you can set the temperature with the original firmware. But once you set it up the way you want there’s no need to change it again.
If its not working for you then you need to change firmware or get a bigger light.

You can not set it precisely by clicking a button (like you can on Andúril firmware), but after the calibration it blinks out the new setting. And mine blinked 65 :slight_smile:

Seem like your set up fine for now then. Hope you enjoy your D4 :slight_smile:

Yes, it’s a really nice flashlight. Anodizing is flawless, machining is perfect and the amount of light coming from it is just mindblowing. Can’t wait for winter, it will be a great hand warmer too :slight_smile:

Can NarsilM be loaded in the D4?

Normal and essentially inconsequential dgq3, you’re going to find virtually all the optics have such markations from the molding process.

Don’t worry too much about the temperature readout, set it for what you can handle and the light will be fine. The electronics can take FAR more than you can. The difference between the readout and your means of measuring the external case are both going to have some variance, this can add up to what seems like a lot, but it’s still all about not burning your hand, so just take care of you and all will be well. :wink:

I think I answered my own question when searching revealed This post

Just need to find that now.

I dont know this has been told… sony vtc5a is great in the d4… i mean vtc5a beat vtc5 by big margin…

Emisar d4 xpl hi 6500k

Sony vtc5a 4000 lumen
Sony vtc5 3600 lumen

That is why I smartly measured the difference at ambient temperature, when the light was cold :slight_smile:

And it’s kinda like a waiter getting used to handling hot plates, I can’t stop playing with it and can already feel my hands hardening :smiley: Maybe in a few months I could add 10 degrees, but the light can not. Well…whatever, it’s not a real issue anyway :wink:
