thanks. took hours. I don’t think nsx4e tailcap is large enough to do more than 2 and retain tail stand. We’ll see this winter…
Two spam posts I marked as spam, one disappeared, but the other one is still here. Oh well. Whatever. Nevermind.
Bluzie has posted a beamshot of the Ni03 SFN55.2. This beamshot is valuable, because the beamshot can be compared with many other beamshots of many other lights taken by the same person in the same location under the same conditions.
NSX4E and NI40 have same tube and tailcup, the issu is on the head NSX4E have more deeper head (less deep reflector for same global size).
SFS80 LED are unbelivable.
For 65$ NSX4E+26800cell+ charger is a very nice deal (I only don’t use charger, I’ve 2 Nitecore Ui1).
I’ve take some pics today for start a thread about this light.
Quick pic for show the head difference.
But , yes the NI40 host is near perfection SBT 90.2 inside for basic version around and under 5 degres celcius outside, you can wait for overheat :heart_eyes:
not a fan of ‘big-head’ lights
need to go in pocket
Saw this Nightwatch Chaos.
https://item.taobao.com/item.htm?spm=a1z0d.6639537.1997196601.4.59897484kqtHbg&id=671140993338
Initial turn on 29-30k possible on the chinese 21700s. (about usd 4.70 for 2pcs).
50 usd for the Chaos.
Not a fan of the format / CCT / yada yada, but it is what it is. usd 100 for 2pcs in both hands gets you past Acebeam X50 territory.
Too bad, OOS now, i think there was still stock 2 weeks ago.
Good price to have 1 in the collection even if it’s just for fun. Also can only buy 21700 cells with lights off TB so that’s another +ve.
Nealsgadgets is selling this same light…
Neal also has the Nightwatch NS59 V1 with 9 of these new emitters, SFQ55’s I believe. It uses two 21700 in series and makes 23,400 lumens on my box, getting seriously hot in a hurry!
Surprised at how nice the tint is, big hot spot area of course but useful in a lot of scenarios.
Nice build on this one, heavily finned like the other Nightwatch lights I’ve had.
These are the kind of lights that make this hobby so darned addictive!
Edit: model and emitter corrections
Are there suitable 21700 cells for continuous 40A on Turbo with a Nightwatch Chaos NS59v2?
EDIT: I measured 48.3A on Turbo. 
The previous version reached 77 C:
Molicel P42A is 30A continuous.
Samsung 50S is 20A continuous.
Lishen?
You can use only use button tops in this light. I tried 30t, 40t and they don’t make contact for series. You can use any other button top cell, but expect a drop in output.
Cool, I see a MSI laptop in the background, I’m sure it’s a GF66
Solder blob a flat top cell, they all work. 
40T is ideal. Heat in the head of the light will be the largest issue, and in very short order!
