Emisar D3AA is available now

Hank just emailed me saying to be patient, they are soon releasing small HI CRI thrower…

Yeah. I don’t know much about it, but it sounds interesting. I sent him a quick test firmware just to help verify if the driver works, and to check if I’ve got the right pinouts… but I haven’t heard any more details yet. Just some initial hardware-enablement type stuff.

Meanwhile, I’ve been enjoying a KR1 W1 in 18350 form. It’s small enough to lose in my purse until I need it, and throws way farther than such a small light seems like it should be capable of. I leave it in lockout mode, with a manual memory level set somewhere practical, so I can just pull it out and use 2H for momentary at a useful brightness. The beam is similar to an Emisar D1S, but the light itself is only a fraction of the size.

Yeah, I'm curious too TBH. There were many Reddit talk about the 14500 model

Thx TK for explanation!

Just something like a FW1A, but with higher quality Intl Outdoor build quality would be great.

That’s what i’m hoping for CC driver and 219B.

[Forsythe_P_Jones]

I hope it uses a t1616 driver.

Thanks, TK!

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.

I’m excited about this, especially a B35 variant.

If there’s a B35am variant, I’m in!

Fingers crossed! Sounds it could be a real winner.

There will be B35AR variant, but since B35AR does not work with DTP, it can only be mildly driven,
the brightness won’t be that impressive comparing to the multiple LEDs flashlight.

I am running B35AR on Eurekatronix board at 2A@12V without issues…

B35AM in my Convoy is pushed to 4A @6V without any angry blue beam.

Nice to hear that, I’m still deciding how much current to use for B35AR. What is the brightness when you drive it at 2A? And which optic/reflector for B35AR?

AM would be preferable since efficiency of a boost converter is higher at 1S>6V vs 1S>12V, but I assume AR was chosen so that the same 12V boost driver for XHP35 can be used.

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.

Sorry Hank but i’m still waiting for meassurement tool to come but it’s bright as xhp35 to my eyes.

But AR is available only in R9050 version only. Wouldn’t it be better to get AM version which is R9080?

At the moment i’m using B35AM in Convoy S21A with stock reflector and 3535 gasket which was trimmed a bit cause B35 is 3636 or 3737 format. Gonna try next weekend with TIR and report which is better.

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

Nice suggestion, we will use R9080 B35AM LED then.

You’re the best, Hank.

The collaboration in the above few posts puts a big smile on my face!

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.
