Emisar D18 introduction

Ok that looks stupid…

Stupid cute.

For a few bucks more….sure.
It’s a showoff toy…

The 18350 proportions look off to me. Functionality wise, if you are carrying such a big light, may as well use 18650’s and have a good grip on the light.

On the other hand, I suspect alot of people would want to buy the shorter tube for a few dollars extra as a secondary option. I would be curious even for myself! Could make a cool table top lantern. That would actually be a good accessory for it, a lantern diffuser made to fit.

:slight_smile:

I agree with both sentiments. Would love to see a 3x21700 tube. With three Samsung 40T cells, we would have max lumens and great run times.

If the D18 requires unprotected button top cells like the Meteor, that might explain why Hank didn’t go this route. 21700s are only flat top I think.

I’m a fan of 18350 but think that tube is impractical and ridiculous. That being said…if it’s offered I’m probably buying one.

3 x 21700 are about the same diameter as 4 x 18650 and only have a tiny advantage over 4 x 18650. Hank wanted to keep the light small.

It does require at least raised flat tops. It should have a ring on the driver like the Meteor and Q8 (based on the battery tube spring board). There are a few raised flat top 21700 on the market, but not too many. There’s even less button top 21700 currently on the market so 18650 does make the most sense.

yes please! Interested

Looks great! I’d buy that. :heart_eyes:

Looks good in 3*18350!
Lanyard hole would be non negotiable, looks like I’d end up dropping it for sure if nothing tethered it to my hand.

+1 :+1:

Hi Hank, for me there is no interest in a 18350 Tube but a big interest in having a 3x 21700 tube. Ist there a chance to get it? 3x 18650 instead of 3x 21700 is the only reason for me not to
buy this great light.

Right, I remember that now. That was weird. I don’t think that sort of thing is likely to be common though.

Yeah… it’s one of Cree’s new rainbow emitters. Someone on reddit posted a 70.2 beam shot recently:

… which is pretty much the entire reason why flashlights are using emitters like SST-20 and LH351D now instead of Cree.

The issue TA ran into is something only TA has had. I’ve never seen it happen, and I’ve tried. More details are in another thread. All tests so far suggest the D18 doesn’t have any issues like that.

I think it looks silly.
Would love to have one.

If you put a space after the final exclamation mark, the picture will show up. :wink:

Some might like the smaller battery tube but to me it sounds like having a sports car & taking the fuel tank off & replacing it with a petrol can.

Pocketable hotrod is what makes Emisar lights unique. You can get the MF01S, which also has 18 emitters, 4x 18650, should be higher output, more focused throw, better heat dissipation due to larger mass and more finning. But it is not pocketable.

Edit: Sorry I misread your post. I thought you wanted 3x21700 for some reason.

I have concerns that 3x18650 can’t properly power this light, can someone tell me how 3x18350 are gonna do anything but get murdered by what is essentially a short circuit’s worth of current?

The short tube makes me want this light, it is cute. Can we get light creeping out of the fins like in the picture? :party:

But seriously, I think the short tube may only appeal to a bunch of flashoholics, but if there’s enough of them it may be worth making it.

IMO it’s the diameter here that limits the ‘pocketability’ of this light (and soda can lights in general). I personally don’t find 3x18350 interesting at all. Length here is not an issue (102mm!), and to have the same diameter and way less power available just doesn’t make much sense to me. YMMV. Also, those wishing for 21700 or 4x18650, lets all realize that the peak power that even TWO of the best 18650s can deliver will make a light this size hit thermal stepdown in a few minutes. Battery power is not a limitation. Also, anyone that may support the idea that that extra 33% runtime you get on lower modes is so valuable, I ask this question: when have you ever used a light in this category on lower modes (of which are achievable in much more pocketable form factors) long enough to deplete the batteries and require a change?

Hank,
I think you did a great job on this light. Proof of that (in my world) is that I was considering myself done with lights of this general type and I’m very likely to purchase one of these. I’m guaranteed to buy this with the availability of HiCRI very near or below the BBL at lower currents. The problem with 18x emitter configuration is that on any sane output level the Amps/LED is in a range that the newest hiCRI options have so much green shift. Turbo should be great though at a ballpark 3A each. Too bad it’ll be over so fast :cry:

PS:
Considering this problem that I just mentioned, I’m thinking that the use of a multi-channel driver that turns LEDs off as you ramp down (for example FET runs all 18, 13x7135 runs 4, and 1x7135 runs one), effectively reducing the tint shift across the output range would be an interesting solution. Complex and bulky though I realize… 2cents spent :beer:
