Anyone has an amber Aux to show?
I am really torn between cyan and amber. Cyan looks so cool, amber looks so comfy…

I’m interested in this aswell. Does anyone know if Mtn. Electronics will be carrying the other color Aux leds?

My D4 actually does a bit more than that at 3170 lumens with a VTC5A, but it’s the earlier CRI80 version with the more powerful driver. It also steps down after ten seconds while the D4S is still at 2430 lumen at 30 seconds.

D4S
0:00 2930 lm
0:30 2430 lm
1:00 1800 lm
1:30 1253 lm
2:00 979 lm
2:30 836 lm
3:00 808 lm

I did not realize that the Gen-1 D4 was more powerful than the current version. Was there a reason for changing the driver to the “less powerful” version?

There are 2 reasons:

 

  • 80 CRI LEDs typically have a higher output than 90 CRI LEDs
  • Nichia 219C LEDs don't really like high currents. That's why the FET channel of the 219C D4 and D4S is capped at 80%

I think that is referencing the new firmware for the 219c version that only goes to 80%.
The 219c puts out 5 hot peppers on the 1-5 hot pepper scale so max output was reduced.
No biggie, it’s still hellabright at 80%.

I doubt that.

Take a look at the D4 config:

https://bazaar.launchpad.net/~toykeeper/flashlight-firmware/trunk/view/head:/ToyKeeper/spaghetti-monster/anduril/cfg-emisar-d4-219c.h

 

The FET-Levels go up to 204/255 - or 80% of maximum. So even with Turbo, you're only getting that value.

To be honest, that's just with anduril, maybe it's different with RampingIOS - but I don't think thats different.

The 219c versions have all FET modes, including turbo, reduced by 20%. This was done at Emisar’s request because people were having LEDs burn out on turbo. It was actually pushing too much power for the 219c 90CRI emitters to handle.

So, instead of 100%, turbo is 80%. And what used to be 10% on the FET channel became 8%. All FET modes are multiplied by 0.8 on that version.

Thank you for catching my mistake, zeroflow. I’ve edited my post and removed the sentence you quoted.

Does the XPL version still go 100% full blast? Or is it 80% as well?

Only the 219C version has its power limited. Everything else runs at full power.

are there different consumption on the aux leds? I read some pages ago that the green ones where more powerfull but I never found out if it measured higher usage or what. I thought that red ones must be good to have because of night vision but if green is more powerfull with same consumption it’s tempting to get a “hulk” D4S (green with green aux).

Who cares ;), get the green hulk. The green is fantastic.

I’d like to see the amber LEDs in a grey or green body, in case I want to get another D4S. I started a thread for people to show off their D4S with LEDs, so maybe we can get the full set posted there.

I’ll have to hold it at shoulder height or they will be thinking BLF’s first radioactive member will be coming down the snicket.

Well, that was easier than expected Smile

I followed advice from BLF forums for the kit, pin mappings, avrdude, and firmware (thank you Toykeeper). I used some 5 Amp fuse wire in the end of the connectors. Now I’ve got Anduril on my D4S.

My thanks to all of you who have been so helpful on this forum.

So which one of the VIA layouts is the final one? the 2×3 or 1×6 ?

Had to make a new “adaptor” for the 1×6 layout Big Smile
Luckily the via distance still matches a breadboard, so i plugged them in, in the correct order and hot glued them in place.

I’ve got a grey with amber in the mail right now. Second to my black/cyan.

You know I was thinking this earlier… For myself though, haha. I honestly like pink LEDs, and I think pink in green would look good. Or pink/black.

From what I've read, the 2x3 was on the first prototypes and on the first batch of lights sold by intl-outdoor, and the 1x6 is on later batches and on those sold by mtn electronics.

 

But there has been no clear confirmation which one is the new one and which one is the old one, but I like that he uses a 100mil spacing. The 2x3 also had 100mil on the 3x side but the two groups were off by a bit.

1. What is the purpose of the auxiliary LEDs?

2. Would it be possible (at the factory) to implement neutral white auxiliary LEDs and use them for a functional micro-lumen moonlight mode? I want neutral white moonlight below 0.5 lumen.

3. Is the D4s intended to be a replacement for the D4, or merely an additional product offering? I really like how tiny the D4 is, and I don’t want to go bigger in an EDC. I would like to see the improvements made to the D4s applied to the D4.

1. It does the same thing as tritium vials… only better. It looks cool and it helps locate the light in the dark, mostly.

2. If a color isn’t offered on Intl-Outdoor.com, it’s not available. But you could replace the aux LEDs with other types if you want.

3. The D4S is not a replacement for the D4. As for the new things the D4S has, Hank might update his older products with newer ideas at some point, or he might not. It’s hard to say for sure. He has already updated the D4 a few times though, and it seems to be a pretty popular item, so I wouldn’t be surprised to see more updates in the future.

Just got my D4S in XP-L HI 4000k last night and all I can say is that its phenomenal. Fantastic work on the UI and the light itself. Threads are clean and smooth, knurling is great, fit and finish is pretty great. Not a huge fan of the lanyard hole because its rather sharp, but otherwise its a great form factor. Im really surprised how much I like the tint so far, I typically gravitate towards clean, neutral white but the 4000k 5D is VERY nice for general use and walks.

Curious though, should the battery ever get critically low from the aux leds, will the light shut off completely with over discharge protection?

The only thing I would potentially change is the “high” setting of the Aux lights, or possibly include a “medium” and id love a candle mode like Anduril has.

I still wish lockout was 4 clicks like Narsil, but im guessing quite a few use momentary if its prioritized.

The main reason I have not purchased a D4 is I’ve read it has no reverse polarity protection. Has that been updated? As Tyrion Lannister says, I get drunk and I put batteries in backwards. Or something like that.

If he updates that and Adds Aux LEDs in colors I’m down.

The low-voltage protection only works while the light is awake. So if something drains the power while it’s asleep, like the aux LEDs do, it can’t respond. About what happens while awake though, I’ll have to double check what LVP does with the aux LEDs. At the very least, they should get dim when voltage is low, or even turn off entirely, since they’re basically direct drive with a resistor in the way to reduce voltage.

Due to the way the aux LEDs are implemented, it can only have three levels — high, low, and off. To do a medium mode, the light would have to stay awake to quickly pulse the LEDs on and off, and that would cost more power than just leaving it in high mode.

If you want 4-click lockout and candle mode, you could reflash the firmware…

The D4S fixed those things, but the original D4 has not been updated in that way. It still has no aux LEDs, and the reverse polarity protection protects the driver but not the battery. But maybe that can be updated sometime.
