NS59v1 was a HUGE hit at the Texas Flashlight Club meeting tonight. It blew everything else we had (MF01S, MF01X, X50 CRI) out of the water.

To be fair, I’m sure the X50 CRI has a rather significant advantage over the NS59v1 Silly

I’m using P42A’s I salvaged from a dead X50 battery pack right now. I’m getting 22,000lm @ turn-on with those. Neal is sending me some of his “special” batteries that will allegedly fix the fact that my sample does not have LVP. I’ll measure output with those too.

And vice versa, since one is 1/4 the price of the other. Here are beamshots if you want to take a look.

NS59v1 & X50 CRI

MF01S 6500K & MF01X

These really don’t capture just how wide and bright the spill is from NS59v1. That’s the most impressive thing about it.

Well maybe, but for the price? No way. I have one hopefully coming for review (if Neal gets around to sending it). On paper, this could be the most powerful affordable flashlight ever. 28,000 Lumens for under $100 is insane. I actually believe Nightwatch Lumen numbers…the NI03 I tested got super close to advertised, off by 150 lumens and I think this will get close to 25,000 on 30ts.

Since this light uses an extension tube, I’m wondering if the driver could take more than 2× 21700 batteries? As it would make for a great long run time baton.

@glenn7, I’m sure it could take more cells. However, you’d have to make your own parallel pack if you do not want to melt the driver lmao.

Why would making my own parallel pack stop the driver melting? I would just use a spacer or solder blobs between cells if the driver could take the voltage.
So I guess what I’m asking is what is the maximum voltage that the driver can take.
BTW I’m quite impressed with this light – a massive bang for your buck! I have had 2x Nightwatch NI40 SBT90 Gen2 (sold) – the switch on the NS59v1 is half as stiff and a much better feel IMO with a loud crisp click with no guess work compared to the NI40.
I don’t think there is a better light in this class out there for the price, might do some beam shots to compare this to the Manker MK38 SFT40 for reference….

OK did some beam shots of a couple of lights.


Shots taken at 2x zoom on iPhone 12 pro max trees on the right are at 70 meters (or 2755.91 inches :0)
First tower is 250 meters, tower at the top of the hill is 520 meters.
First is the NS59v1-Turbo

Next is the Manker MK38 SFT40 – Turbo

Next is just for a bit of fun – my old custom X-led that has 30 x HXP70.2 and does 50,000 lumens straight for 40min, then you can change out the Ryobi battery over and over. It has a really wide beam that can light up everything at an angle of 200 degrees, it has a switch to make the beam narrow for throw or wide for an area light it also has a dimmer knob and 2 speed fan.

X-led with throw turned on.

I know, right.

That's about two to three times as many tabs as I usually have open.  :BEER:

hahaha yes I’m the tab king, lots of cross referencing and unfinished reading also some maybe-purchases happening….. which makes it easier on a 49’ screen – actually I mostly split viewing into 2, watch pay-tv on half and have my million tab browser on the other half.

Sorry for the ramble but I am quite proud of this light and every time I bring it out, most people say WOW! that’s stupidly bright then why do you need such a bright? (me slapping my head) So you guys are the only people that get it.

Yes the Xled light is a beast, I bought the very first light with this amount of power from the company that makes them (not cheap) They were using a different less powerful led (can’t remember) so I suggested they use the HXP70.2 – and they did! they said they could make it go up to maybe 100,000 lumens, I choose 50,000 lumens because I wanted efficiency and runtime without too much heat, rather than shear output.

It has a tripod mount for an area light (which I wanted) the optics that they used has a mix of throw and flood but as they stick out the front, they shine backwards in your face hence the 200’ beam – I asked if they could make a shroud to cover the sides to stop side glare, they said they would make me one but it never happened so I made my own by bending a strip of alu and gaff taped it on to try – haven’t done anymore as it protects the optics and stops side glare and it just works.

I bought it in 2015 – by selling a kidney on ebay :0)
I’d like to get it updated to their new throw optic and SBT90.2 but I only have one kidney left – Hmm I do have 2 lungs…. If anyone is interested I think they are in the Netherlands and this is their website

Anyway the SN90.1 holds it’s own for it’s size, it’s a comfortable to hold size, just when you think these leds aren’t getting any brighter….boom! they do – maybe not so much brighter but the lux/intensity they are doing is leaping ahead.

Great light!!! Unlike a soda can type of light, it fits in my hand nicely, is well balanced, and has a simple UI. Very impressive flood with a little bit of a throw too.

 

Thanks again Freeme!!!

LVP Update!

Neal sent me his “special batteries” which appear to be Lishen 21700 HP’s with a brass button soldered to the flat top. After more testing with those cells and more P42A’s, I’ve determined that my sample DOES have LVP and it works reliably, leaving the cells at ~2.8V after shutoff.

The thing that killed my first batch is parasitic drain after LVP shutoff. I measured cell voltage after LVP shutoff at about 2.8V, then turned the light back “on” for a little over an hour. When I checked cell voltage again, the cells had dropped by ~0.2V each!

When I did my initial runtime test, it was overnight. The light was on for an hour or so but then shut off (due to LVP, apparently) but when I checked voltage in the morning the cells were down near 1.5V! Looks like parasitic drain after LVP shutoff is the culprit.

Wow that seems like some pretty significant parasitic drain.

Indeed. I tried measuring it and ogt 650 microamps. That’s not very high and I don’t think it should drain the cells that fast, but the voltage difference doesn’t lie.

How do the 21700HP’s compare to the P42A’s in terms of max lumens?

At 2.8v the amount of energy left in the cells in very minimal so even a small current drain will make the voltage drop a fair bit.

I have not tested extensively but one quick test indicated similar max lumens. I will have more details in my full review.

I saw this flashlight on TB too late, about 2 weeks after it sold out there. This light is super value for those just after lumens and nothing else.

Just managed to snatch 3 pcs of LS 2170HP (3000mAh) and LS 2170LA (4000mAh) and 2 of his 4-bay 2A per bay quick chargers. Darn cheap, the batts are only 15 rmb and charger 30rmb each. Shipping usd 6 to my country (just nice 1.00kg, if it were 1.01kg i’d have to pay 0.5kg usd 3 more)
Batts are for my 2 Jinheng JKK76s.

Just for everyone’s info, NW Chaos hit like 3 seconds above 25k……but that might be due to several factors as well. eg the best of his lot of Lishen 2170HP etc.

Anyway NW sells 2 types of LS 2170 HP 3000mAh. One ver is for this Chaos, the top has a brass disc soldered on. The other version is normal flat top, stock.
I got the stock version for my JKK76 coz its battery carrier already has a disc built in, so would easier to fit in (esp since i am contemplating to squeeze a few bits of rolled up aluminum foil to try to create a bit of bypass, so the springs are not gonna compress as much with those bits in, coz the light is claimed to be DD in turbo).

I do hope the ones i get from NW are indeed 7-8 mohms. Some other TB sellers’ Lishen HP cells are doing 13-16 mohms from what i see in the china TB user reviews in the item listing, while some are 7-8 mohms.
If i remember correctly, Samsung 50G is doing around 15 mohms, so…… (i use 50Gs in my Amutorch DM70 quad XHP 70.2, good for 23k thereabouts as tested on the meter)

Got mine today. First impressions.

- Well made, body and knurling is perfect.

- Wow lots of lube on the threads, like enough for 5 flashlights.

- Small dent in the bezel due to sub par packaging, but you can hardly see it.

- Again due to improper packaging, the battery close to the head had its positive totally crushed in, it still works but I’m sure the contact is not great.

- The batteries were sitting at like 2.8v when I received it so yeah there is some parasitic drain. They seem to be taking a charge.

- The switch is OVERLY sensitive, very hard to do a double tap without turning the light off.

- Very bright, any complaint you could have just goes away when you hit the turbo.

I got mine its good overall with a few quirks

  • The battery tube is small, the Sofirn 21700 cells are very tight and my battery tube has a tight spot in the middle where the cells get stuck.
  • Switch is soft and easy to activate once the light is on, these are the same switches used on the L6 so it should feel similar but its the design of the tail cap. Switch is to far back a new washer will fix this i think?
  • My lens came with some greasy oily finger prints on it, they where hard to clean lol
  • Not really a quirk its expected but it gets really hot quickly, to the point where it could be dangerous so don’t throw the light in bag unless the tail cap is undone.

Mine too! The cells Neal sells are a super tight fit. Really satisfying, but there is that tight spot in the middle. I have to open mine from the middle of the tube to get the batteries out as a result.

Is yours a reverse or forward clicky? Sounds like a forward clicky from your description. If so, I want to trade! Haha

Does yours have anodized threads on the tail? Mine’s threads are all unanodized so nothing short of removing the batteries will lock it out.
