Emisar D18 introduction

How does this new flashlight compares with the 'competing' astrolux MF01S? It also use 14 Sst20 leds but claim 1000 more lumen!

I feel like a competition is starting to come!

By the way, here are my suggestion! I like the desgin a lot! I hope they will be one with 'clear anodize' finish!

give me copper please i dont care about it being super heavy

huh mf01s isnt even prestented yet or is it ?

Texas Ace is the one who worked on the MF01S and advised he’s not signed off on the final lumen output as he still hasn’t received the final prototype.

Astrolux pushed that out ahead of schedule to answer the D18

MF01 mini & MF01S dropped today

Freeme confirmed
MF01 mini GB begins April
MF01S GB begins June

He’d never be able to source enough with a decent consistent bin

If I am not mistaken, the Astrolux uses batteries in Series, and the Emisar uses batteries in Parallel.
For that reason alone, I would pick the Emisar over the Astrolux.

I think the Emisar is also much smaller compared to the MF01s.

D18 is def lighter and smaller. I’m not a big fan of the aux leds.

If I can - why could he not? He can order through digikey 5600pcs per box with a 6 week leadtime….all the same W6 bin that is higher lumen bin than the Cree XP L he carries……

Arrow even has free shipping for the T6 bin (6wk mfg leadtime also)

I imagine Hank knows better than probably anyone in China where and how to get what parts he wants….even if other manufacturers are unable or unwilling to do so for various reasons. Just wish he would do it - I would love Emisars D4S and D4 with LH351D….

Always good to have competition I think.

Does anyone know why sst20 is use instead of cree xml or other? I understand if cri is required, sst20 or nichia 219b is excellent, but for lumen maxness, why not use cree led or luxeon v2? Or maybe I am not understanding something.

I hope someone can have them in hand to do side by side competition test!!

This looks amazing, gonna be an expensive year for flashlights I think.

Typically for these lights they are looking for something that fits on an XPG footprint. That rules out SST-40 and XML2 since those are larger LEDs and take more space.

Some LEDs have domes that are too big to fit under standard optics: Example: XPL HD

For LEDs that fit under optics we have the following choices:

  • SST-20 - good lumen output, excellent CRI and throw, but can be green-tinted. Also gets hot fast due to low Vf.
  • LH351D - excellent lumen output and CRI, but quite floody.
  • XPL HI - excellent lumen output, throw and tint. But not high-CRI and quite expensive.
  • Nichia 219B - the recent bin used by Fireflies was excellent, but this is an older LED and supply is limited or completely unavailable. It’s also not very bright.
  • Nichia 219C - decent LED, but pretty much everything the 219C does, an SST-20 or LH351D does better.
  • XPG3 - cheap, but inferior to SST-20 in output, CRI and throw.
  • There’s also a few oddballs I’m not familiar with so can’t comment on (Oslon flats would have lower output but superior throw. Not sure what Luxeons would do).

My guess is they chose the SST-20 due to cheap per-unit cost, high availability, overall pleasing beam pattern with good throw, and CRI options. You would get higher output with XPL HI and the light would run cooler, but 18 pieces of XPL HI is expensive and might literally double the cost of the light.

Each optic clearly is in a holder that touches the MCPCB literally 360deg, as with those type of optics, you can’t put any PCB under the optics to put any aux LED, it’s not the type of multi optics that rest on a few legs.

Hank, will you supply different optic choices that people can buy independently to customize their beam profile?
Also out of curiosity, are these single TIR optics taller than your standard Carclo triple optics?

I love that you went the extra mile to condense the LEDs and minimize empty space.

This is an excellent review and summary. Thank you very much for your time to explain to new user like me. This makes a lot of sense and now I understand why sst20 is such a good choice.

It’s probably gonna drop the output really fast I assume, right? It seems pretty small for the output it has. My Q8 is bigger and has 1/3rd of the lumens of this light.

Is there a list to get on to reserve one, or just keep checking the website?

They don’t do lists or sales, I’m sure it’ll be listed shortly on the website.

I just recently purchased a Q8 and, (IMO), it’s a brick and too dang big. This looks more like it as far as size and brightness goes.

That’s the way it goes in our super rapidly evolving light world! :slight_smile:

I wish this had USB-C charging port too. I would buy a bunch of them for gifts because my contractor friends are going to love them. Sofirn was able to add USB-C to the 3x18650 SP-36 so I’m sure it’s doable here too.
