[M4D deal] Nightwatch NI40 with Luminus SBT90 Gen2 interest list OPEN

Thanks, I found a converter from my Sky Lumen Delta accessories and I put a Sanyo NCR18650GA 3500mAh 10A Battery into the Ni40 SBT90.2. I couldn’t really tell by the eyes how much output/center lux I was getting, plus it was day time so my room was already window lit by natural lighting. It seemed quite impressive but without a side by side to another light it’s hard to speculate numbers. The hotspot is pretty large! It seemed larger than my Acebeam K75vn hotspot if I recall correctly.

Extremely usable spill, with minimal corona around the hotspot. Nice defined hotspot edges so I appreciate that as a thrower guy.

I would imagine this particular 18650 is nowhere near close to the ability of a Golisi on turbo?

Can someone please hypothetically relate the estimated difference in max turbo output between the 10A NCR18650GA Sanyo VS the 30A Golisi 4300mah (gold) in the Ni40SBT90.2?

SBT90.2 VS SST40 Dedome…. results are shocking? He’s not using a Golisi, so it’s only supposedly pushing 20A instead of 30-35A, but it’s still not looking very good for the SBT90.2… I couldn’t play it with audio, so I was just reading what he wrote on the cardboard towards the end.

I’m not sure but the one with SBT90 could have a wider hot spot beam which is nice and allows you to actually make out object further, or it could have a better spill around which could be useful even if it looses in the absolute throw distance to the dedomed SST40

He was using a Vapcell 5000 which is worse than the shockli 5500 and the shockli 5500 is worse than the golsi/aspire at high currents. About a 0.3v difference at 20A. This means that with the Golisi/Aspire it should be around 35-50% brighter at turn on. I’m not sure how accurate my numbers are but I do know that it should be performing better than in the video. We’ll have to wait for more testing to really see how it performs.
Below are beamshots taken by Bluzie of the Thrunite Catapult V6, FT03 SST40, NI40 & Olight M3XS-UT Javelot. It seems to throw as well as the FT03. In a pic he showed a keeppower 5200 next to the light. This cell has pretty poor performance but I’m not sure if it’s the one he used.

Olight M3XS Javelot 250Kcd

One things for sure, the SBT90.2 has aLOT of spill power. Check out the difference in the ground immediately below the tripod! No other light of that bunch comes close in output.

I’m really hoping for 300kcd at turn on, because I am giving away my Sky Lumen Delta to a cousin tomorrow. 465kcd in that and I’d prefer not to lose too much throw as it’s my only real thrower at this point.

It would be hard to call myself a flashoholic and not own any light over 300kcd haha. Otherwise I’ll be purchasing a new dedicated thrower in the near future.

I don’t think the pictures are exposed right. The catapult doesn’t have nearly this much spill and same for fo3 if that’s the sst40 version. SBT90 seems to throw better than ft03 though as the objects in the hot spot appear brighter. Also looks like a slightly wider hot spot, which I suspected, and that’s a hood thing usually. This abt90 spill is what I am actually worried about. If the pics are in fact overexposed, the spill may not actually be that bright.

I own both the catapult and the ft03 both versions

A lot. There’s no 20A discharge curve for the GA but the 15A one shows a 0.31v difference. I doubt it’s even getting past 3000 lumens so i’d say at least 40-50% more output.

Received my cells yesterday. They measured at 4,242mah and 4,166mah

In a MF01 Mini with SST-20 4000K, Golisi 4300mah cell got 3,860 lumens at turn on compared to 3,770 with the Vapcell/Shockli 26650 5500mah which measures about 6,000mah. I’m pretty sure the SST-20 4000k was already pushed to the max. I hope to see a bigger difference with the NI40 SBT90.2. Still waiting for mine.

My Three Golisi 26650 4300mAh got 4350mAh,4332mAh and 4268mAh with my Opus.

Where did you buy yours from?

lol! The same places that I recommended to and linked for you. Vapewild and 3Avape.

When I bought mine Vapewild only had One. I bought the other Two from 3Avape. A few days after I received them from 3Avape, Vapewild had re stock! :smiley:

I tested both my Golisi Gold 4300 and Vapcell 5500 on my MF01 mini. Both pulls in 23 to 24 Amps on the tailcap on Turbo. I’ll try again with a much thicker wire.

Found this on YouTube. Head is 52 degrees at 15 seconds. Doesn’t make sense. Maybe he turned it on earlier?
NI40

With this thing pulling 24 amps, it doesn’t surprise me at all.

All these beamshots are nice but has anyone actually measured throw and lumens output on a specified cell at a specified voltage? Seems strange Bluzie got one to take pics of but no measurements? I'm in the 2nd batch I guess, waiting for it to be shipped.

Here are some comments from TLF by the user who posted this video (LightintheNight). I’m kinda confused now cause according to Nagonka the 40T was 32% brighter than the Shockli.

I do not know if this works like this …. but I tried with very simple means to display the first 4 minutes of the control with temperature measurement. Safe far away from professional and only for good eyes, but just handy :wink:

Edit: a few more comments …

- Use found a full Samsung 30T battery with 4 or 5 charging cycles, but now has a deepTop ;-(

- the lamp was running all the time on Turbo, in another attempt in high regulates them The first few minutes hardly down

- the 30T had just after the 4 minutes turbo only 3.8 V

- the 30T brings a slightly higher turbo brightness than all the 26650 batteries that I have tried before

  • the lamp was not quite cold to start, because I previously 26650 batteries have measured briefly, ie the whole should be extendable by 10-15 sec

Have times a few details added above, was with 30T battery …
@ hjelpestikker With these batteries, I had compared the starting brightness …. The difference when starting on Turbo (pure data without conversion): - Shockli 5500: 367 - Keeppower 5200: 372 - Thrunite 5000 (evidently protected): shut down - Imalent 4500 (mE protected, but left): 369 - ijoy 4200: 366 - Samsung 30T (21700): 376 (not quite full, in the video then complete even 388 ) For comparison: at high, the value was at all around the 300 Lg LitN

I hear ya! Cant wait till someone from blf gets one to do a proper review…
I personally dont have good equipment to measure (just my phone) but I will when I get mine. I’ve got a shockli and a some golisi cells coming, should be here before the light.

I’d like to stuff this led into several different size lights to find it’s best home. I’m thinking its going to be something with a 3” head or
bigger, and 3 or more cells. I have a tn32 with a bad driver, that will be first. I’ll have to get creative to make it work.

I agree. Looking forward to you and other testing it.

To the best of my knowledge and based on output,The life of a Golisi on max[increments of 5 min.] will not be much more than my buddies MT35 W/XHP 50.2. Turn on was 4100L

5 minutes-3.83V
10 minutes-3.62V

It drains the battery as to be expected. That is why I have 3 X Golisi and 4 X Aspire. :sunglasses:

I got a modded triple XHP50.2 3V light that hit over 30 amps off a fresh GOLISI, so high amps draw is fine with me. The main thing is how this light does on throw, compared to the 220 kcd rating. It's the simplest thing to measure, in fact I find it wayyy easier than doing beamshots, though results may and will vary. I got 3 light meters and they have about a 5% variance range.

This SBT90.2 sure looks like it beats the dedomed XHP50.2 and the dedomed SST40 in throw, and of course much higher in lumens. Not sure where it is head to head with a XHP35 HI in throw, but the XHP35's require a special driver because of the 12V and restricted amps.
