Emisar D3AA is available now

My D4SV2 with the SW35 is sitting in a distribution centre right near my place and it’s killing me. I’ve got a battery ready to go and I keen to see what these emitters will do in the D4Sv2 body!

With freshly charged 30Q 18650 cells, D18 219B vesion turbo current is 48A at turn on, that is 2.67A per LED,
which I think it’s still within safety line?

In that case, D18 219B version should be with direct drive, no current limit.

Sounds promising. :) Do you have some Samsung 25S or 20S to test with again? These are supposed to be the most powerful 18650 cells available. If D18 219B works with them properly, there should be no way of killing these LEDs. :D

How many 219B SW30 and SW45K do you have left?

Oh and by the way, Hank did you have any chance to take a look at my previous post?

What do you think? :)

Default original optic back in stock for D18. Also can now select Nichia 219BT-V1 3500K and 4500K emitters. Order placed.
Hoping for tint below BBL with nice light pink hue, Thanks to Hank Wang for all your efforts. You are the best!

Haven’t had a shipping notification for a DT8 with SST-20 5000k after 10 days. Is that normal?

I ordered on 13/7 and got shipping notification only on 23/7. I assume he must be very busy with the 219b orders. (and I contributed 2)

Hank is in overwork
Please be patient

Good to know. I’ll keep waiting patiently!

I love the DT8 in 219BT-V1 4500K emitters it’s so ‘dinky’ much better than the D4V2 which i never really took a liking to.

What would be estimate the maximum and highest sustained lumens are for the 219BT in the DT8?

it is not "out of line" to send him an email (reply to your order confirmation) asking for update. After 10 days I would send one to check in. That's not unreasonable. I've done it once or twice before .

Just got the shipping notification now - 11 days after order. Hank must be a busy man!

We have one D4V2 in Australia, 219B 4500K LED, with flat retaining ring, extra flood optic, 18350 tube, and magnetic tailcap, original price is $60.17, now, 30% off, which is $42, shipping included, for Australian customers only, PM me if you are interested. ———Sold

Nice deal!

D4v2 219b 4500k arrived today, I love the Cyan color and raised switch.

I recommend getting the 219b while it’s available.

My sincerest apologies, I must have missed your post the first time around. I know I’m super late but I figured I’d at least answer your question in case you’re still wondering.

If you want excellent output, I imagine the K9.3 shoud be pretty good, maybe even the DT8. If you want super output, the D18 would be King. If you want sumtin pretty and mega output isn’t a major factor, def go Copper D4V2 all the way, or I guess the Raw Ore. Again, my apologies for such a late response.

So unless I’m reading it wrong, it turns out the D18 with 219B’s, WILL in-fact surpass 10,000 lumen at turn-on? Roger that. :heart_eyes: :heart_eyes: :heart_eyes:

Thanks Hank

I just did some admittedly ass-backwards math. But at 2.67A per LED, I’m getting about 645 lumen per emitter and over 11,000 lumen at turn-on.

Am I pretty far off, or at least in the correct neighborhood?

Here is some community data that should be pretty accurate, as an alternative to trying to read the tiny relative output graph from the Nichia datasheet:

Rather than just settle for the closest reported current, I did the math to interpolate and got 605 lumens per emitter. You also have to consider losses from the optics. I don’t know what optic the D18 is using, but a Carclo 10mm TIR is supposed to be 92% efficient with similar sized LED’s, so that makes it 557 lumens per emitter.

That would suggest right at 10,000 lumens, if it really is able to pass 48A at turn on.
