The hottest hot rod?

Interestting!

Just a small correction: the unit of the hotness rating doesn't fit the numbers. It should be klm/cm3

It seems correct to me…*k*lm/mm³.
Or lm/cm³. Which seems more natural…and I switched the spreadsheet to use it.

CRX, that Tool must be HOT !

Yeah I changed it soon after to a 7135 driver I think.

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. :slight_smile:

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. :slight_smile:

The new Imalent LD70 - built-in battery (18350?), XHP70.2 and 4000lm :open_mouth: this

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.
