I was thinking in terms of which version of Anduril I should flash. I don’t see an SST version.

Well, I received my D4S with the SST-20 5000k.

It does have a light green tint to it in moon mode, that gets whiter the brighter it gets. And I cant say with complete confidence that all the green is gone at full power, but its real close.

It sure throws better than the XPL-HI 5000k, perhaps adding close to a hundred yards in throw.

And it has better definition than the HI, to me. I am able to see texture on trees and stuff that I can not with the HI. Could the greenish tint help?

After all is said and done, the SST-20 is my new fav out of the Nichia, the S4 3D and the XPL-HI.

Of course I may prefer the S4 3D 4885k in thick timber, which I have not had a chance to try out yet. I hate light reflecting back into my eyes, it blinds me somewhat and is a distraction. With the reddish tint, I notice very little reflection.

I hope this helps someone.

Thank you for your feedback learningtofly it comfort me too in my decision. smile

 

Did you notice a big difference in heat generation between the XPL-HI 5000k and the SST-20 5000k?

The standard version. You only need to use the 219c version for 219c or low Vf emitters like maybe an XP-L2 if that were offered.

Standard version goes to 100% FET
219c version goes to 80% FET

I ordered from Hank:

Emisar D4S 26650 High Power LED Flashlight
Color – Grey (smooth surface)

There pretty close, but it feels the HI gets a little hotter.

So I have a question: I just received my d4s (black, D4S SST20/5,000K, red aux) and in comparison to my 2 d4 flashlights the LEDs do not line up real well under the TIRs…. it makes for an oblong beam on one end….. Is this normal for this config? Am I being too picky?

I ordered the exact same D4s setup you have, will let you know when I get it if its got the same issue.

No, that doesn’t sound right. It shouldn’t be oblong.
Shoot Hank an email or PM.

My D4S sst20 have a completely normal beam.

Yes, mine has a well defined, round hotspot.

I’ve actually received lights that Custom’s apparently disassembled and didn’t put back together right. The worst was a Mateminco X6s triple, they let the triple optic shift completely off the emitters and the bezel wasn’t on properly of course. Crazy stuff happens out there!

I thought it would be the opposite, XPL-Hi 5k seem to be the more efficient option for the heat, but i'm glad to hear your feedback! wink

If the SST-20 5k is at least close in heat generation it's perfect for me.

I got my d4s sst20 5000k today and its great. The highest 3× 7135 mode is very nice.

One thing I noticed. from moon to highest 3× 7135 the light has a very nice yellow/very slight green tint. When ramped above the regulated current the tint really gets whiter. Can it be that the pwm got anything to do with it. Its a pretty big difference and its perfect for me. Like high cri on the low and low on the high mode.

LED tint changes depending on the power level.

This is generally most noticeable on a FET+N light with a relatively low “N” and a relatively high FET level. I try to reduce the effect by blending channels, but there’s only so much it can do. Without the blending though, if I set the FET channel to exactly the same lumen level as the +1 channel, and alternate between the two, it causes the color to change while the brightness stays the same:

The light on the left is just there for reference. On the right is a BLF-A6 which changes tint every half second by changing which power channel is active… yellow, blue, yellow, blue, yellow, blue.

Maukka has also measured this effect in great detail, in most of his reviews. Look for his charts showing where the tint is at different output levels.

Very intresting and exactly what i meant in my light. I actualy really like it! Does the sst20 have more output on the 3×7135 level than the xpl hi?

Anyone notice/try Shockli green 26650 5250 mah cells? Unprotected and seem proper dimensions and specs. “On paper”, seems no difference from black except nominally more capacity (black says 5500).

Well, I found HKJ review now so I see it seems inferior to black, but has anybody used in their D4S?

Anyone measured the current draw of the new aux LED colours and if the efficiency is materially better or worse than the original cyan colour? I guess each colour would be in line with Lexel’s values stated for his custom D4 boards ?

I have ordered a few D4S in different aux-LED colors (I ordered not for my own, but for a local flashlight community here..)

I did test the power draw for the different aux-LEDs

(cyan & green are earlier batch)
aux-LED in "Low" mode --- in "High" mode
cyan: 0.07-0.08mA -- 1.1-1.2mA
green: 0.07-0.08mA -- 1.1-1.2mA

(amber & red are a more recent batch)
aux-LED in "Low" mode --- in "High" mode
amber: 0.08-.09mA -- 1.5-1.6mA
red: 0.08-0.09mA -- 1.6-1.7mA

The current draw for the amber & red (recent batch D4S) are a bit higher than the cyan/green. Yet, the cyan and green aux-LEDs look MUCH brighter (when aux-LEDs are in "High" mode -- they are nearly as bright as the lowest Moon mode on the main light)  Whereas, the red and amber aux-LEDs look quite dim (even if they measured higher current draw).

Aux-LEDs are in High Mode (camera exposure time is 1/25th second)

Aux-LEDs in Low mode (camera exposure time is 1 second, pardon the blurry pic)

(the D4S with blue aux-LED is using a frosty optic)

is there a tutorial or something to follow to flash anduril in the D4S?

I just measured the D4S with SST-20 3000k 95CRI at 2,328 lumens at 1s with my TA Lumen Tube. It is less rosy than the 3000k HD2 tinted emitters from Kaidomain and the SST20 3000k used in the NS22. It might be due to the optics. The XP-L HI v2 version measures about 3,577 lumens at turn on.

Also previously I read someone posted Hank said the 3000k is J4 flux bin but the spec sheet only shows it going up to J3 so not sure if Hank got a special batch or if the J4 was a mistake.

I have this exact light (well, it’s twin). You will love it. I had green Nichia also, until my wife commandeered it.

Together with the battery, it weighs 223 grams.
