Emisar D18 introduction

Great work Hank!

Hank, how much will it weigh?

Make a 26650 attachment!

Totally agree… as lumen increase, bigger capacity are needed…

I have 15000 lights and 4 x 18650 doesn’t provide enough capacity.

26650 would be absolutely monstrous. Way too large IMO.

What could be actually done is an 6x18650 extension, in parallel of course.

That will probably have more probability than the BLF Q8/Lantern extended tubes.

Ok. Do whatever it takes. 18650 is old!

How about 2x 21700 in a side-by-side configuration?

Thanks for the write-up! I didn’t mean to insinuate that Hank made a poor design choice, I should’ve been more clear that I just didn’t understand how it all works. I see now that it will be a very fine light.

Are 30Qs no longer best choice? I know the sony VTC6 was a contender at one time, but I’m not sure the current best choice. What should I get for this light? I am buying this light haha.

Remember that the batteries are only going to give what they can. The voltage will sag and the current will be less compared to 18650 cells. So output will be less. I would not worry too much about the cells getting “murdered”. Lol

30Q is a really good compromise between high discharge and high capacity. Most lights don’t need the extreme discharge capacity of a 25S. Another good thing about the 30Q is that it’s relatively easy to find and inexpensive.

I come from the drone flying hobby, where lipos can and will puff and burn if you pull more amps than they can handle. Even with voltage sag, you can easily pull over 100amps from a 1500mah 4s pack. But if you do that for more than a few seconds at a time, you murder the pack lol

That the Meteor M43 has retained its status as a classic for as long as it has is a testament to the quality and practicality of its design and fabrication. Even the D18 is only an incremental improvement, although a welcome one. I think we are seeing the birth of another benchmark classic - a practical one. Thank you.

I loved the M43 right off the bat, but the UI left a lot to be desired for me with my horrid memory. So ultimately I changed the driver and at the moment I have it running so hot it glitches Anduril in about 15 seconds on Turbo. :smiley:

I learned though from that, when I built Ham’r I used 5 drivers. lol (3 different emitters in 5 variations)

Is there a beamshot available for this light? Keen to see how those little TIR’s perform… they look similar to some I bought to fill in gaps but ended up not using. Should be pretty neat though… can’t wait to find out.

I’m still struggling with the vision of Newlumen powering 15,000 lights on 4 18650 cells…

Mateminco mt18 modded with xpl hi.

Looks like I can finally replace my meteor. What is the maximum fully regulated output?

I suppose it will use all 14 7135 chips at 0.350A each so that’s 4.9A.
Then 4.9 ÷ 18 is 0.27A each. I think the sst20 will do maybe 70 lumen at that output so that’s roughly 1260 lumen. We won’t know exactly until it’s measured, but that’s probably the right ballpark.

The cooler temp leds might be higher than this and the warmer temp leds might be lower.

Excellent. Even the highest regulated mode on the D4S puts out a substantial amount of light.

If the XPL-HI 3A fit and are available in the future I am in for 2 of these. :wink:
