Emisar D18 introduction

At very low current (<100mA) efficiency become decrease.
Unfortunately no test at BLF has low current range.

I too am interested in what choice of optics there are. I’m not really familiar with this type of individual optic per emitter. One thing I like about the Meteor (and D4) is the availability of different optics to adjust the beam from a balance of throw and flood (e.g. the Carclo 10621 or 10622) to very floody (e.g. the Carclo 10623 or 10624). Are there similar options for the type of TIR optic that the D18 will use?

Hank,

Can I ask, what is the diameter of the individual optics?

I love passion combined with quality :+1:

Apologies for the long post. Trying to answer some questions all at once…

It really does. Dale makes some insanely bright lights, and when I turn this on at turbo, I get a taste of how Dale must feel. Even without optics, it’s very bright. It’s like turning on 15 to 20 60W equivalent light bulbs all at once. Normally I find even two of those bulbs to be excessive for an average room, but the D18 turns a room into something surreal like in a movie when they want to convey a holy aura or something.

Probably. The MCPCB is screwed into the same piece of metal the switch is in.

Yes, the boost driver components took up a fair amount of space. I don’t have my Meteor apart to compare, but I think the extra space has been converted into additional thermal mass to help deal with the crazy amount of power running through the D18.

I’m not sure there is even anywhere to put aux LEDs. The front surface is packed with white LEDs and I haven’t seen the optics but it looks like there may not be any room for anything else.

This light has no aux LEDs, so the firmware is built without that option. However, RampingIOS V3 and Anduril have the same aux LED controls so it makes no difference which is used.

OTOH, lightning mode would be fun on such a bright light. :slight_smile:

Probably not, but I’m still trying to confirm that. I’m not sure if Hank is willing to change the UI significantly from previous Emisar products, but I made Anduril available just in case.

I don’t think Hank plans to use Anduril, even though I keep asking him about it. :slight_smile: He’s probably sick of it by now.

In any case, when I update things in Anduril, I also apply those updates to RampingIOS V3. So it has received several updates since the D4S was released. I’m not sure it will make a meaningful difference to anyone, but it has at least received bugfixes and some small UI tweaks.

Also, XP-G3 makes an ugly rainbow beam. :frowning:

Yes, it won’t sustain 14,000 lumens for extended lengths of time. Something this size simply can’t soak up and shed 200W forever, because physics. The batteries can’t sustain it for a long time either, because it’s an awful lot of current coming from each cell. I’d estimate the maximum turbo runtime at about 10 minutes, with water cooling. But without cooling it’ll step down sooner to protect itself.

???

It’s a pretty well-tested setup which has worked fine on many lights for years. In this case, it ramps down to a moon mode of about 1.7 mA, which should provide a runtime of about 9 months per charge.

Sometimes I use car headlights as a unit of measurement, because it’s something most people are familiar with at night and it works out to a nice round number.

The D18 is similar in brightness to 14 car headlights all pointed at the same place, except the beam should be more focused so it looks more intense.

It also has lower modes though, for the times when we don’t want to blind anyone. ~0.2 lm to ~14,000 lm, in a smooth progression of 150 levels. To select one, simply hold the button and then let go when it reaches the desired level of brightness.

M43 was also constructed in the same way and still crooked. I had to drill holes again and make new screw threads.

I am a dedicated Emisar fan so of course I will have this, unfortunate that a XPL-HI option would be so expensive though. I have a good many flashlights that are EDC appropriate but I do EDC my D4 with XPL emitters. I like Emisar products for the hotrod wow factor so the D18 with a emitter that is pure show off would be nice. Not worried about heat and output stepdown with a hotrod. I was also hoping that the next release from Hank would be a D1s with 26650 cell.

Looks nice, 14000 lumen really a lot. actually i dont going buy D18 because i have not needed for powerful flashlight with more than single cell. and i already have one soda can torch

you completely right.

I was disappointed when the D7 (or was it D8?) was scrapped. I’m very excited that Hank doubled it and then some! Really cool, especially in the 3x18650 smaller diameter.

Absolutely. One trauma resolved! And I’ve always preferred 3x18650 over 1x26650 as well. :sunglasses:

Don’t we all!

Do we sign up, or is this first come first serve?

I’m only on page 3 so I don’t know if this has already been mentioned.

The MT03 has been known to have multiple issues. The locating pins in the tail cap breaking off, shorts in tail cap, the FET leaking and/or burning out. Also, not everyone likes the yellow corona of the 70.2. You kinda get used to it, but it’s probably ugly compared directly to this Emisar light. Keep in mind the MT03 is bigger and uses 4 18650. That can be good or bad depending on your preferences.

Hank, thanks for creating and executing another fantastic light!

If there is enough interest in the 3*18350 tube, sure we can make it.

I’m interested in the 3*18350 tube.

The light already seems a little too stubby as it is. You guys are weird. :stuck_out_tongue:

Same LED arrangement as Foursevens.

Except TIR instead of reflectors. Plus way, way cheaper! Lol

A 3x 18350 tube would be great. :person_with_crown: It would still output almost 10 000 lumens and be a huge advantage over the new MF01S. :laughing: I’m sure nobody would complain about an almost cube formed flashlight! :stuck_out_tongue: :wink:
