Emisar D4S review

I agree.

I am happy to wait and see what Hank brings us next.

Delighted with the D4S.

I was really intrigued and delighted with the 7x XP-G2 DQG and found it to be an excellent foray into the multi-emitter market, keeping in mind too that they do trend towards minimalist design. Ultimately though I discovered that the driver output so closely matched a Cree COB in high CRI that I made some up-top changes and now have an excellent camera light for macro photography that is capable of 2004 lumens with zero artifacts and zero hot spot/beam disturbance. Love it in this mode! I affixed Velcro to my lens hood and can easily strap the DQG COB light onto the hood so the source is directly in front of my subject, works so well I have thought about acquiring two more to make an array of 3 lights around my macro lens for the ultimate in macro lighting. :smiley:

Edit: The finish and knurling on the 7x DQG is top notch, my favorite factory knurling of any light I’ve seen, bar none…

And in the COB mule configuration, priceless to me…

Paired with my hybrid 100mm Macro IS lens on the Canon 5D Mk IV, images like this are just exceptional…

Wait there is more… fireflies rot 66.

My D4S arrived today :smiley:

Nice !
I don’t think I’ll buy it, because I know it would be a shelf queen, but if I had to I would chose red Aux LEDs too !

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?

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.
