Mines been ok from KD, pretty much normal, 2/3 weeks, sometimes quicker.

I waiting two orders (13/03/2020 and 29/03/2020), both SG registered shipping.
The one from 13/03/2020: 2020-03-26 Despatched to overseas (Country code: UY)
The one from 29/03/2020: 2020-04-04 Information Received – Item En Route to Postal Facility

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.

Ban

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.

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?

I’m still waiting for an order I placed 80 days ago. KD keep asking me to wait. An order I placed a couple of weeks after this one took 46 days to arrive. I’m not being unreasonable in demanding a refund, am I?

An order you placed 80 days ago ecotack? Well, now that I recall I have two pending small orders from FastTech, one of them placed march 23 and shipped march 30 (78 days total, 71 in shipping). Regular mail.

I have a friend working at my local post office which last week told me they were receiving/delivering packages from February.

I have never lost a single shipment, no matter if untracked. I'll wait some more weeks.

I’m still waiting on some AliExpress stuff from February and early March. There were a couple shipments that never showed a single tracking hit. Those got disputed and I got my money back. But if there’s been any hint of the seller actually having shipped the stuff, I’m giving them the benefit of the doubt as shipments are certainly backed up. I’ve seen a lot of headline horror stories about the shipping industry lately. As for me, I’m just going to sit back and be patient.

I can’t speak for the UK, but I’d say what you’re experiencing isn’t unheard of right now. Sucks, but that’s the situation we’re in.
