Yeah Iām going to use a bench top power supply and see how low I can drop the voltage. Hopefully itās simple and doesnāt damage anything. Also hopefully this picture of the battery uploads right. If not hereās the link
Ho, sorry, Iāve forget itās you who have say he can try with external power supply.
Normaly no, just open the circuit
Thankās for sharing
Strange ācustomā, If they works
Never see button top solder in this way.
HP remember Nitecore classification cell, same cell with same capacity with various head, HP/HPI ā¦.
Holy crap! Has anyone confirmed this light actually has temperature control?it gets too hot to hold and fast! Love the amount of light but Iām going to need gloves the next time I use it.
@madcrisis, the temperature control does work, but I think I saw one of TacGrizās post and the temperature at which the flashlight throttles is rather high.
To be honest though, this was not unexpected: youāre consuming about 200W+ on turbo, which mean passive cooling in this form factor is out of the question.

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.
Cant wait to get mine! :sunglasses: What cells were you using?
To be fair, Iām sure the X50 CRI has a rather significant advantage over the NS59v1
Iām using P42Aās I salvaged from a dead X50 battery pack right now. Iām getting 22,000lm @ turn-on with those. Neal is sending me some of his āspecialā batteries that will allegedly fix the fact that my sample does not have LVP. Iāll measure output with those too.
To be fair, Iām sure the X50 CRI has a rather significant advantage over the NS59v1
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 donāt capture just how wide and bright the spill is from NS59v1. Thatās the most impressive thing about it.
To be fair, Iām sure the X50 CRI has a rather significant advantage over the NS59v1
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 numbersā¦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, Iām wondering if the driver could take more than 2x 21700 batteries? As it would make for a great long run time baton.
@glenn7, Iām sure it could take more cells. However, youād 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 Iām asking is what is the maximum voltage that the driver can take.
BTW Iām 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 donāt 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 referenceā¦.
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.
30 XHP70.2??? HOLY COW!
Those tabs though, SHEESH!
Anyway great beam shots, that home made xhp70.2 looks epic!
Those tabs though, SHEESH!
I know, right.
That's about two to three times as many tabs as I usually have open.
hahaha yes Iām the tab king, lots of cross referencing and unfinished reading also some maybe-purchases happeningā¦ā¦ which makes it easier on a 49ā 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! thatās 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 (canāt 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 200ā 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 - havenāt 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)
Iād 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 lungsā¦. If anyone is interested I think they are in the Netherlands and this is their website
Anyway the SN90.1 holds itās own for itās size, itās a comfortable to hold size, just when you think these leds arenāt getting any brighterā¦.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!!!

Do you plan on reviewing it?
