    Default The Brightest Flashlight with One 18650 in the World

    Hey guys:

    ThruNite will launch a new model soon.

    It will be the brightest flashlight with one 18650 in the world.

    Guess and comment here how much lumen we can make it.

    Very bold move! According to Cree's data sheets, the XM-L U2 maxes out at 1040 lumens. My best guess is that you'll be using multiple emitters run from a single 18650? Will it need IMR 18650's to run? It takes 3A to hit the max output for an XM-L, I'm not sure if ICR 18650's can do much more than that.

    With a U2 bined XM-L, 3 amp (IMR driven) and a copper heatsink I guess ? Hmmm... around 850-900 lumens ?

    You can buy a Quad XP-G that will put out 1780 Lumens on one IMR 18650, so it must be higher than that. An IMR 18650 could theoretically put out up to 10A, so you could run three U2 XM-Ls at about 3A each, for around 3000 Lumens.

    The brightest single 18650 flashlight would be no doubt VanIsleDSM's septa, with 7 XPGs, it has around 2500OTF lumens measured in a sphere. That's a tough goal to beat IMO. If this new light only has 1 XML, then it's not going to be the brightest, regardless of drive current.

    For a somewhat safe operation on ordinary high quality 18650 (not IMR)...

    A triple/quad XM-L U2 in parallel, driven at ~5 amps total, with heat protection circuit, perhaps ~2000 led lumen and ~1500 OTF. Hopefully it is smaller than the smallest triple 18650 lights, otherwise it wouldn't make much sense.

    If it uses IMR, the numbers could be doubled (4000lm & 3000lm), but the runtime would be very short (due to heat and cell capasity).

    Is that a custom build? I did a few quick searches and couldn't find much. To be fair, don't think we should expect them to beat what a custom maker can do

    I am sure Thrunite is only comparing this to production lights, not one-offs or custom 'waves'

    Well the Septa, as well as all the Quads and Triples XPGs are still in production and you can still get them. Either way, if Thrunite is aiming to beat those customs it's a really high goal. However, if the goal is simply to be the brightest "production" light, the ceiling is not too high, 3 XPGs or a SST90 at 5-5.6A (the highest current a burned in SST90 will take from a 18650 due to its high Vf) should do it. To beat the customs, it will have to be 3 XMLs at least...

    Any way, quite interested to see what comes out of this, although i would be dissappointed if it's just a "1000 LED lumen" single XML light.

    I'll guess 2000 lumen...... but will it be regulated?

    I'll take some popcorn.

    Think between 800-1000lumens with a single led in the light.

    Then it would only have 30% of the output of the brightest single 18650 light, so highly unlikely.

    That's good & amazing news.
    I guess around 1,000~1,100 lumens, but assume it needs a step down regulation within 2~5 minutes to protect emitter & circuit & 18650 cell.

    Sting. Sting would be another person who's a hero. The music he's created over the years, I don't really listen to it, but the fact that he's making it, I respect that.

    Will it have a tailcap made from a more durable substance than plastic?

    1200 OTF would be my guess.

    Can you give us a time line? A hint of whether it's a single or multi emitter?

    One LED.

    I think we will release next month!

    Might want to change the title to, "The Brightest PRODUCTION Flashlight (With one Emitter) with One 18650 in the World" Lol.

    BC it clearly wont be the brightest 1x18650 if only one emitter...

    This light must use the SST-90, the Elektrolumens Big Bruiser is close to 2000 Lumen, DD on a 26650.

    Either way:

    Agreed. What is max spec on the SST90? Would an IMR 18650 be able to get it up there? I think probably. Maybe a 1X18650 with that CBM360 (not even sure if that's accurate)?? Flood monster! Again, don't know if a single 18650 could do it.

    Anyway, SUBSCRIBED.

    That depends ENTIRELY on the answers to a few VERY big questions flying around. But if you can really beat other very bright 18650 lights out there, and by enough of a margin to make the claim in the thread title, there's a good chance I'll own one.
