I have a bench top power supply at work I can test it with. Didnt even think about that. When it comes in Iā€™ll bring it to work and check it out. Freeme says below 5.6v should auto shutoff so it should be pretty quick to verify. Just need to get my hands on the light first

Actually going to be a bit longer for me to test this out. I got my tracking information mixed up with my convoy order. My ns59v1 is still tracking as in China. But I will test as soon as I get it if no one else has yet.

Does anyone have sustainable output numbers for this light? Runtimes? A beamshot would be nice too.

Will include all that in my full review. For now based on the one runtime test Iā€™ve done, Iā€™m getting just under 2000lm sustained for about an hour and a half on P42Aā€™s.

The thing with P42A from observations with other high current lights, is the 30/40T can ha dle higher initial current loads than the P42A can. Itā€™s as much as 15% higher vs a 30T, which is a lot.

The writing on the switch looks like ā€œOmten PBS101ā€ according to Omtens website itā€™s rated for 3 Amps at 30 Volts, i wonder how it will hold up

Thatā€™s a pretty robust switch good to see a name brand in there too. Itā€™s also meant for AC 125V and 1.5A so that gives you an idea of itā€™s rated capacityā€¦about 190 watts on AC and probably 60 A on DC.

I didnā€™t realize it took button tops so the batteries rattleā€¦ā€¦ got to buy new batteries.

Edit: What batteries should I get?

You should get this high technology solution

And for me you need rewrap cell for verticale rattle, tube is little too wide.

extension top cell is necessary to use 40T with near same high technology solution.

Iā€™ve lost my picture when I show differeenc between 40T and P42A with they raised top who make contact for P42A and no contact for 40T.

If you are in EU I check on NKON they sell P42A button top, but 2 ā‚¬ more the p42A flat top.
Or any 21700 unprotected with button top you found :slight_smile:

Iā€™ve realize my picture shot with this ā€œrondelleā€ inside my light.

I donā€™t understand the Nightwatch choice for need button top 21700 on this light.
This?

Use for 26650(NI40) and 26800(NSX4E) cell , too wide? O_O.
But itā€™s fun to see Nightwatch/Neal response, I warned

I also got 40T cells, do you think a neodymium magnet has too much voltage drop at those amperages? I think itā€™s about 8mm diameter

I leave this answer to more knowledgeable people.
Iā€™m under amateur level for this skill, for me metal is metal, if thatā€™s work :frowning:
But magnet is advice often give.

Those magnets have high resistance unfortunately and arenā€™t a viable option. I donā€™t recommend them for that. A copper spacer is a better option. You can solder it directly to the brass driver contact to take up the space requirement.

Thanks for the ideas, in the pics it looks like the driver has a brass post which should work fine with flat tops, just the connection between the cells is not given. Maybe Iā€™ll bend some copper wire to make a spacer until i have a brass plate or something better.

2,000 or 20,000? 2,000 seems a little low for sustained output.

If the flashlight starts at 22,000 lumens, I wouldn't be surprised if the sustained lumens are only 2,000 lumens.

Unfortunately, that's pretty common with flashlights.

Itā€™s about 2,000lm sustained. Not very high, but itā€™s not that large of a light and I suspect itā€™s using a low efficiency driver, so 2,000lm sounds about right to me.

I believe itā€™s to ensure the two cells make contact in the middle. Two flat top cells may not make contact in the middle of the tube, unless the tops are a little bit proud like P42Aā€™s.

I was browsing their site recently and every single push button switch has the exact same full range of specs listed. Seems like not long ago they listed everything as AC amps but everything there now says the same 30V/1A/3A, same resistance, same cycles. Maybe thatā€™s accurate if they all use basically the same mechanism. We know they can handle quite a bit more than stated anyway.

In another thread someone suggested that one of Simonā€™s lights had a ā€œmore robustā€ switch but couldnā€™t back that up with numbers or anythingā€¦doesnā€™t look like an Omten (not on their website anyway) and I couldnā€™t find a switch/brand with the same markings. I think some of the cheapest cheap cheapie switches use inferior plastic that will melt or deform at lower temperatures, maybe poorer springs, but so many of these are like the same switch with different contact configurations or footprint sizes. Ones used in our typical China flashlights at any rate.

Has anyone ever tested the resistance/voltage drop and/or upper limits of current for neodymium magnets when used as contact points? I was thinking about this a couple times over the last yearā€¦canā€™t find any past threads or reference on BLF but it seems like I remember hearing it mentioned long ago. I suppose it would have variables that include the grade of magnet, quality and micron thickness of the nickel plating, contact pressure between points, etc. It would be interesting to see the numbers, though, for something like a typical N35 lower cost version.

2.000 on static environement, probably at 20 celcius degres.
In exterior in dynamics environement in night at 10-15 degres can only increase this base perform.
This is the dissociation to be done on these tests.
The EC06 who was a brick have close similar perform compare to test environement statics
Any host with an effort on thermal design have a much bigger difference between the test indoor and the reality outdoor.
Of course, more the night is cold, more the perform is high more the gap is high between brick and host with fine :laughing:
For example my Nightwatch NI40 with SBT 90.2 under 5 celcius degres was pretty hard to overheat, itā€™s a real pleasure to use :smiley: , In summer at 15-20 degres itā€™s really eazy to overheat and have a burning light in hand :slight_smile:

In fact with this thermal design, use this light with an other for creat a duo is interresting, they heat down very fast when you donā€™t use.

So 2K sustain on static is good, memory EC06 sustain 1500 lumens at static environnement 20 celcius degres so :laughing:
With this design, no reason Nightwatch too low

If anyone have lumens output at medium, I can compare (feeling only) with my two light during a night walk.
For check if I see with naked eye difference between one light after 10 (or more) minute at medium and light not use with full cell.
No my interrest yesterday just fun for this quick use, In fact I found the body was ā€œcoldā€ for a nightwatch with this output with reasonnable heat at head and a sensation of cooldown at medium after hard push in High/turbo, Not stay at high temp in head with reasonnable output on medium mode.
Its assumption for the moment I have to try it more, but the first impression after 2 hours outdoor is really good about heat gestion.

Off course, you are in right, I had forgotten this notion :cry:
