Neal sent me photos ( and also an incoming light ) of his newest Nightwatch NI40 but with a new OSRAM led, the S2WP.
The current page in Neal’s site of the NI40: Nigthwatch NI40 (the S2WP not yet included )
Compare its KCD to the other leds, not bad throw and lumen output combination at all!
————————————————————————- the NI40 in between the NA40 (top) and the long throw Flat-White-equipped IRA-lite series.
The Osram LED on the picture is not a white LED, maybe a blue or a green one (there is no yellow phosphor on it).

the phosphor is yellow, this is clearly seen on the reflector op
True, then the lighting of the pic must be very weird (or it's a photoshopped pic).

Anybody have more info on this new emitter? From that pic I would make a hot take that it’s basically 4 white flats on a single chip much like an XHP.
If those output/throw numbers are accurate there could be some CANNONS made with it. Wonder what kind of numbers it would get in an L2…
It’s quad q8wp, one generation behind white flat.
3V as well I’m guessing? I’d like to see what it can do in a 26650 tube-style light like the S11, would have a pretty useful beam profile and some serious output it seems.
That super cold color temp is a bummer though.
If I remember correctly, all dies are driven separatrly so you can configure it to go from 3v to 12v.
What going on with the xhp50.2 beam profile?? Forgot to remove the blue filter???
funny eh?

I really love how Nightwatch offers the best leds around. Dedomed sst-40. Sliced and diced xhp50.2. S2wp. White Flat. Nearly all the best choices out there.
At the same time I really really miss good e-swich ui…….and I so dislike the bulk added by tail clicky…
More thoughts:
Anyone have a datasheet on the S2WP. I just got Nightwatch sample from Neal with it, but can’t find anything about it. Love the consistency of the tint though. No rainbows here.
Found it: https://dammedia.osram.info/media/resource/hires/osram-dam-7378054/LE%20...
Around 6000lm at 20A in 4P configuration.
But why do we need it? The SBT-90 Gen2 has a single die of basically the same size (=> no donut hole) and is really not too expensive for what it does. The luminance should also be similar. I guess a 2S2P or even 4S configuration of the Osram LED might make sense in some applications, the drivers are smaller and cheaper this way.

Received two Nightwatch NI40 Stalker 2019, one has Osram S2WP led and the other a Cree XHP50.2 blue led from nealsgadgets.com
————————————————————————————note: the XHP50.2 is a ‘blue’ led
Additional pictures to follow as the current weather is not cooperative and some time constraints.
Why this XHP50.2 DD look so odd? It looks difrent than all the de-domed XHP50.2s I’ve seen so far.

It looks like they removed all the phosphor…

Oh, sorry, I forgot.
That XHP50.2 in the NI40 is indeed blue light.
Oh yeah, that must be it.
Only now I noticed that they list the lights on the website alredy….
Any chance for a discount?
Hi tatasal,
I would be VERY interested into testing the NI40 Stalker with Osram's Stage S2WP LED but I feel somehow reluctant buying one as a friend of mine lately got a sample of the NI40 with really poor build quality (fingerprints on reflector, crooked tailcap spring, missing thermal compound, razor-sharp threads with bad machining).
Can you please find out some more information about this special S2WP version?
Thank you!
“Everyone, deep in their hearts, is waiting for the end of the world to come.” (Haruki Murakami, 1Q84)
Oh, I wish I know the answers to some of your concerns.
Beamshots to be taken when weather permits.
As for a discount, I will ask Neal and post it here if ever there will be one.
All right, just to make double-sure.
So the XHP50.2 De-domed means it’s a blue led without dome? If so, can you please confirm the performance numbers in the table are correct?

Beamshot from the CW S2WP. Wide spill with a medium sized spot. Very even tint with no discoloration.
A thrower (Emisar D1S) for comparison at the same distance (under 2 meters from the wall)
I’m getting 20A on turbo, which is activated with a double half-press, but it’s a bit too hard to do as the off timer is very picky about the speed. The firmware needs tweaking for sure. Most of the time a double click just advances the normal mode cycle. I didn’t even realize there’s a turbo mode before. In addition the half presses need to be kind of deep but not too deep not to activate the mechanical switch, otherwise the light flickers between modes and since some steps are very small, it’s difficult to tell if you’ve managed to even advance to the next mode.
There doesn’t seem to be any PWM on any mode. Practically no ripple at all either. But there’s a strange bug I haven’t encountered before. After first activating turbo and then coming back to a normal mode, any of them, PWM is suddenly there at 15kHz. But it’s gone after advancing to the next mode.
Here’s what one of the mid modes look normally
Here’s when I activate turbo with a double click and come back
I thought the nl40 had a smooth reflector?

Is this a tail switch light?
Yes, tail switch.
