It’d be interesting to add a couple of bigger ones on here, to see how they compare per cubic centimetre (such as Imalent’s MS18 at 100,000 lumens).
Some other single 27100 lights, around 9000lm:
Nitecore TM9K
Imalent MS03
Nightwatch NS53A
The Astrolux EC03, Lumintop FW21 Pro and Fireflies E07 are all around 6000lm, so probably won’t make this list.
Could a single 18650 the size of a D4 drive 3 XHP50.2 LEDs over 10,000lm?

You could also add lm/gram unit, but also unit which would tell how long those lumens can be sustained (for ex. before OTP kicks in, or brightness drops below 90% of initial max. lumen, whichever happens first), units could be lm*sec/cm3 , and lm*sec/gram.

The three bullet pointed lights that you mention: The first and third fit right in my hot rod collection, among the hottest rods for their size. The second one: I ordered two of them from my favorite USA supplier.
Lumintop FW21 Pro, 3 x XHP50.2 3V: Neils website says ~10,000 lumens, I submitted a serious inquiry to my fav light guy for three of them, he says he is checking on latching onto a batch of them.
Y, t a h n m f n r a n h g! Yay!

You’re welcome to add these columns.

Thanks, MS03 made it to the top of the list!
I’m not a fan of this brand but nevertheless I’m impressed.
Does anyone know tailcap diameters of TM9K and NS53A?

Added the NS53A’s tail diameter of 28mm.

I don’t see on your mods list. I’d like to add it to the table but I see that it is available with 2 different tails, could you please indicate which one did you use?
Thx.

It was a short lived direct drive version with lighted tail . I didn’t make a thread.

BTW, I find it curious that you got 1900 lm with SST-40 yet Vinh gets 1600 with XHP50.2 3V

Direct drive, cracking bin LED, cell used, ANSI standard, planets aligned, different equipment...
I see vinh recommends to use the Vapecell 3A 14500, prob used that for testing.
I used a WindyFire red 14500. Don't get too caught up in the numbers.

I liked this thread so much, I started a similar thread on pocket throwers over here: In search of the best pocket thrower flashlight (lots of research)

very interesting database, thanks for the insights.
Yup. He also did some amazing projects. Not only 14500 and when I read your post, the first thing I thought about was 458 HAM’R

Thrunite TN50 CW is pretty hot. Its 4 21700 batteries are wired directly. The company rep told me they use LG. Wow imagine if it was VTC6A or 40T

Thanks for this very interesting hotrod list.
I wonder how the FF ROT 66 Gen II w XPL HI would rank. It is supposed to spit out 14k lumen stock but it’s probably less. The light is quite compact though.

I don’t think they’ll come close to the top…but you’re welcome to add them to the sheet.
I wanted to add it but there are no dimensions given. Anyway I actually don’t think it’s very hot compared to the small lights listed here.

That one from Djozz is nice,too:
Not long ago I did a direct drive mod with this small AAA-size light . (details on the host can be found there, and in a thread about this light )
[image]
Everything very well connected, XM-L2 on copper, Efest 10440, it did over 500 lumens for 3 minutes (that is a significant part of total battery runtime already, 10 minutes at what I guess is 2+ amps). But, even tiny as the light is, 500 lumens is not always practical, especially since the beam pattern of such a small light with an xml favors c…
