Nice suggestion, we will use R9080 B35AM LED then.

You’re the best, Hank.

Regarding current handling, on a MCPCB with high thermal conductivity dielectric and thick copper pours it is reasonably good (7.6W/m.K, 3oz pours):

But those high perf MCPCBs might be cost prohibitive.

Any cost associated with maximizing thermal performance at the mcpcb is well worth it. I’d gladly pay an extra 2 or 3 dollars per light to keep these Nichias cool. 3oz copper pour over the whole board and the thinnest dielectric should be sought out.

You won’t find me disagreeing with that Big Smile , I also think that people will be very pleased with the B35A so this is worth it.

Just a note: AM is 6V emitter where AR is 12V.

I have both and they can take serious current. I’ll send some info over email next weekend.

What thefreeman and JaredM said, this emitter will be WOW as i’m now in my builds. You won’t regret it paying extra bucks for every quality component!

And which optic/reflector for B35AR?

Ledil Olga RS produces a very nice beam with it IMO, what optic size are you considering ?

Olga is a nice optic, and LEDIL is a generally a good choice IMO. The Olga RS will probably be the best for SFT and maybe XHP35 HI where absolute max cd is the goal, but for the SST40 and B35, check out the Gaggione LLC25N. It’s a similar sized optic without any injection sprue so the bezel / oring design and machining will be simplified. This line of optics is color mixing and doesn’t project a ghost image of the emitter in the corona. Cd/lm is on par with the Olga RS for larger emitters , both offering about 14cd/lm for the B35.

https://www.optic-gaggione.com/wp-content/uploads/products/LLC25C/LLC25X...

https://www.optic-gaggione.com/product/llc25n/

compared to

https://www.ledil.com/data/prod/Olga/16671/OLGA_FAMILY_20190702.pdf

https://www.ledil.com/product-card/?product=CA16672_OLGA-RS4

If any 1mm² or 2mm² Osrams or Cree emitters are also offered, I’m not sure who offers the best cd/lm and clean beam in the ~30mm optic range. The Gaggione LLC05N is rated at ~145cd/lm for the 1mm² flats which is impressive IMO.

Yeah I have a few Gagionne lenses on my wishlist, still haven’t ordered yet because the shipping is expensive despite same country shipping Sad , I’ll add this one.

I don’t see any ghost image of the LED with the Olga though. I’ll take a pic once I have installed it in a light.

Apparently, the new thrower will use TIR optic, 21700 cells and one of the following emitters: SST40, SFT40, Nichia B35 and XHP35…


Let’s wait.

This is sounding great, especially with the LED.

Hank, can you say roughly how big the head diameter will be? I’m picturing this as about 40mm but I could be completely wrong.

I hope it’ll be less honestly. We have girthy models already, let’s make a slimmer one

Yeah, slimmer would be good. The KR1 is 35mm though, so this new thrower would probably be at least that wide.

Head diameters:

  • D4V2 28mm
  • KR4 29mm
  • KR1 35mm
  • D1 35mm
  • D4S 39mm
  • D1S 50mm
  • K9.3 52mm
  • D18 58mm
  • K1 72mm

Loneoceans used an Olga in his awesome KR1 mod. https://budgetlightforum.com/node/76271

I would really love to see it be no wider than the KR1, and possibly narrower. I’ve been wanting a Noctigon FW1A for a long time. Wink Something I can comfortably carry all the time.

This looks awesome, though:

D1V2 size would be nice, but a bit thicker since it’ll use 21700.

If it could take auxiliary lights and also house Getian FC40 that would be awesome!

I would happily do without the auxiliary lights if it means a better price. Simpler to mod too.

If TIR will be installed then aux lights could be the option. Just look at Loneocean’s build

Yes, I have both the AM and AR, and was trying to decide which one to use, thanks for helping me to make the decision.

Yes, you nailed it, 40mm head exactly.

Please just make the best light possible and don’t worry about the cost. None of these lights are really unaffordable and we all have lots of lights. If the new light ends up using more of our flashlight budget, it just means we buy fewer total lights. I’d rather have two or three great lights than spend the same amount on five crappy or compromised ones.

After checking both AR and AM are available in 9080 : http://www.nichia.co.jp/en/product/led_product_data.html?type=%27NV4WB35...

The choice between the two is rather about efficiency (AM/6V preferable).

An additional LED that could be offered with it would be the XHP50.3 HI, if it proves to be good. A 6V driver here is also preferable for the same reason and that the MCPCB is just a simple XM one.

Looking forward to this light! Thanks Hank!

Bonus, if it takes off the shelf TIR optic from Ledil or Gaggione, people can customize their beams if they chose to make it floodier than stock.

Sure, we will use the most high quality MCPCB and parts with it.

I hope it will retain KR1 look and not Sofirn IF22A…

Hank confirmed 40mm so it won’t be as many dreamed pocket friendly.

And that’s why we will keep paying a bit more for your awesome quality lights, keep it up mate

as much as I would love to see the AR being used for the 12v compatibility of the Xhp35 HI (3000k hi cri and 4000k hi cri), and also possible mods with the gt fc40 leds.... - I do like the sound of higher efficiency in the 6v variant and the compatibility of the xhp50.3 HI

 

my first vote would definitely be for 12v b35AR, because xhp5.3 can be made this way too. but If I am in the minority here please let me know..
