Mostly, see here: https://download.luminus.com/datasheets/Luminus_SST-20-WxS_Datasheet.pdf

 Seems like you need 3500K or lower to have bins 100% below BBL: https://www.mouser.com/datasheet/2/245/Luminus_SST-20-WxH_Datasheet-1499224.pdf, like for GA2 and GA3

That 5000K L5 DD would be amazing if bins are true. Highest possible flux bin with a tint similar to the Cree 3A!

I have serious doubt that FD2 is legit. I’ve come to believe that Luminus don’t even make this bin. But I will buy one just to try it.

The JA3 is a very nice 2700K. I tried Fireflies version and it is one of the better WW emitters I’ve tried.

Looks even nicer with a slice. Hotspot get’s super small though.

I have not received any confirmations that the FD2 bin can be attained with the K2 brightness bin yet.

BanL, are the JKK lights your design?

The low mode should be lower.

I do not think so. They can be found in many strange stores on Ali. I bought in one of them.

I know shipping times are kinda long now, but still gotta ask because one of my order got here pretty quickly which I ordered at 24/02/2020, but two other orders 17+18/03/2020 havent arrived yet. Same shipping method un-registered airmail. Anyone else has similiar waiting right now?

Yeah just like my first order. Well gotta wait. Ordered XP-L Hi 3000k CRI90 for swapping into my SRT7 and some centering rings. Well just cant do more than wait some more and not much use for lights anyway in summer time until autumn and darkness comes again.

I was going to say “pretty good R9 values” in the above table by SKV89, but after going to quote the post I see the 70+ figures are for R12. Now I see how it works, but it's weird to see that the table frame isn't shown or is set invisible. Maybe it is easier on the eyes to list the value identifiers, a colon, and then the corresponding value (R9: 22.7 R12: 72.6 Rf: 82…).

Received a package with a K6 flashlight host I was waiting for. Weighed 348.0g in my scale, which seems to be more or less well calibrated (also weighed a couple VTC5A cells multiple times and they ended up averaging 47.8916̅g).

Took some photos:

 

 

Beefy, tough host. Minus the knurlings tube wall thickness is ≈3.5mm, and it still hovers around 2mm at the back where the tailcap thread is (2.4 - 2.5mm thread included). Maybe it's not a tank, but it's armored.

Bezel diameter 62.6mm.

 

 

I was at first going to complain about the lens, but it looks that way because it comes with protective film either side…

The stock switch is a forward type one (17.9 × 12.9 × 13.5mm lenght × width × height). Will have to swap it.

All measurements taken with cheap Aneng caliper.

 

Host related question for BanL, is the S3 21700 using the same reflector size as the S2 21700 (also known as S21A)?

Hi

Their reflector is not the same.

Another little question. 

Of course I am in need to replace the stock forward switch in the K6 host (can't say it makes me happy, honestly).

I am dealing with a little doubt concerning the most compatible replacement for the stock switch. I could use the PBS101C400 I have around here, but I'd like to get a more direct replacement, and stock a few spares. I have nailed this down to the

 

 

OmTen PBS101C190 or the OmTen PBS101

I couldn't find the PBS101C190 in OmTen's english website, PBS101 model list. Had to say, just in case the model went out of production or whatever.

Any other suggestion welcome.

All those switches will likely perform similar, if they fit they are fine.

I hear you djozz. The only issue is dealing with the current metal centering washer which sits atop the switch, as it is ∅10mm whereas the above emitters need ≈∅8mm. Will have to make or obtain some adapter.

I’ve just received an order of some 2mm^2 OSRAM KW CSLPM1.TG 5P-FCBB46-15 WHITE 5400K from KD which are my first experience with any of the osram FW led’s, be it stock in a light or stand-alone for modding so I have no other point of reference but they all seem really cold white, atleast 6000k minimum, probably cooler.

Is this to be expected and normal or should I suspect bad reflows making them blue shift cause of heat?

To clarify this is strictly a question, if it’s normal I’m not complaining at all as they do perform in the lights I’ve put them in so far but just wanted to be certain I’m not experiencing a problem if they should be warmer.

What amps are you running it at? IIRC around 5A is max for that LED

Without actual tint and color rendering tests of the current CSLNM1.TG batch from Kaidomain (or anywhere), it can be hard to precisely determine those parameters by the naked eye.

Crap I copy/pasted the wrong page! Im running the 2mm^2 OSRAM KW CSLPM1.TG 5P-FCBB46-15 WHITE 5400K which as you can see is binned, according to the KD info, specifically at 5400k, not a range like the 1mm^2. That actually makes me a bit more on edge, it’s just so far above 5400k it’s hard to believe it’s within spec and not gone AngryBlue™.

Both lights with them installed (both are exhibiting the same AngryBlue™) are running at 6.8 and 7A. Should be well within safe range.

Right, and I’m not claiming “oh jeeze these things are 6341k” or anything like that. I have no test equipment other then a lux meter nor do I care about specifics. I’m also not targeting 5400k precisely that if it’s not exactly there I’ll be upset. I’m just worried about a bad reflow job cause when I shine them on a white wall next to a knows 6000k CREE XM-L2 they’re several shades more blue.

I have the drivers set to single mode only 100% and when I first fire them up over about 1sec the blue seems to get deeper (and then hold at that level for the remainder). So far I’ve only ran them 20-30sec at a time for fear of killing them.

KD reflows on 20mm boards, good heatsinked hosts, genuine AS5, MCPCB’s screwed to shelf.

I’ve used one of the 5400K 2mm WFs from kaidomain and there is a significant blue/purple tint. I don’t think there is anything wrong as far as overheating. Another user had the same concerns with the LED color as you a few weeks ago.

I have a feeling the LED is way below the BBL which gives it that tint. As far as color temperature I think it’s hard to tell when the tint is way off the BBL. So maybe it’s not as cool as it first looks? Try it outside, I actually came to like it.

Here’s a test I did on a 1mm2 from L4P long ago, very high CCT on all of them I think.

Quote:
BLF X5 (White Flat 1mm2 from LED4Power)

Hot spot:

CCT = 8823K (Duv -0.0110)
Color Rendering Index (Ra) = 69.6 [ R9 = 2.6 ]

Spill just outside hot spot:

CCT = 6701K (Duv -0.0048)
Color Rendering Index (Ra) = 67.5 [ R9 = -19.0 ]

LoL contactcr, these are way off CCT specification figures. How the reflector plays with the output spatial distribution matters, there is a huge difference between hotspot and spill. Did someone cared to notice angular tint shift in these Osram emitters?
