Emisar D4S review

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.

But the red is so nice also :smiley: Look a few posts above I’m afraid that the answer is to get both lol

Violet would hint as Hulk’s pants.

Just an idea.

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.

Hot pink aux lights and body for t’wife?

Nah she’d stand out too much in “the dangerous place” and probably die :stuck_out_tongue:

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.

I mean the wife will have to hold it at shoulder height :blush:

Well, that was easier than expected :slight_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 2x3 or 1x6 ?

Had to make a new “adaptor” for the 1x6 layout :smiley:
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.
