OSRAM CSLNM1.TG & CULNM1.TG 1mm², CSLPM1.TG & CULPM1.TG 2mm²

The thing is with specific regulated/linear drivers, they are fixed size. Right now I can do about any size in a FET+1, from 15 mm all the way up to SRK size, and lots in between combined with filing down, etc., plus I can configure them for power or e-switch lights.

Sort of related, looking for a decent host for these LED's, I do have a couple Cometa's and one B158. I did find FT has the B158 in stock at $29 with the BLF code, but I'd prefer a B158B and it seems no longer available at GB. I only have one B158, wish I got the B158B's when they were there. Now, Brinyte is under new ownership or something, or sold the B158 line - looks like they gave up on the B158. I messages with a rep a few weeks ago - the Brinyte that is now is not the old Brinyte, so not looking good for the B158's - what a shame... I think/believe the B158 is still bout the best throw for it's size around.

Of course there are many other lights/hosts that would do.

Oops, here for $26: https://www.aliexpress.com/item/Brinyte-B158, and here w/red for $25: https://www.aliexpress.com/item/Brinyte-B158.

Worth to mention that B158 beats all commercial available 50mm aspherical flashlights when it comes to throw… All that with super cheap 2$ acrylic lenses.

When I was telling that to certain Copyfire factory they just ignored me… They stick to their production and lenses vendors and that’s it.

Also worth to mention that B158 lens will give less die projection than other 50mm aspherical lights.

How much you can expect with White Flat? Mine cheap Uni-t Light meter says 420kcd! Yes with FET DD setup( I am obviously brainwashed hehe :slight_smile: )

If you find one please let me know

I searched for it less than 2 months ago and it appeared gone everywhere.

So here’s my 2 cents.

I Built a C8+ (stock AR lens) with white flat CSLNM1.TG on Noctigon xp and LD-4 driver. After doing measurements hand-held at 5 meters I decided to get out my tripod for more accuracy in measuring lux at different currents.

Keep in mind that the led is very close to center but not exact with stock xp centering ring not yet focused.

So here are my numbers:

At 4.50 amps - 160,500 cd - 801 m
4.75 amps - 163,700 cd - 809 m
5.00 amps - 167,500 cd - 818 m
5.25 amps - 168,575 cd - 821 m
5.50 amps - 169,750 cd - 824 m
5.75 amps - 166,250 cd - 815 m

Measurements done with 1330 lux meter corrected to .93 to match known lights.

For some reason I can’t get the driver to do 6 amps but as you can see with my setup the output peaks at 5.5 amps and starts to fall after that. Normally I’m a numbers guy but it doesn’t make any sense to drive this led harder than 5 amps. I’m inclined to run it even softer at 4.5 just to give it better battery life and generate less heat. The loss in candelas is a negligible trade off.

As noted before the led doesn’t like to self center on an xp MPCB so that is a challenge. I look forward to trying on a 3030 board. The stock xp centering ring is also sloppy because the hole is larger than the led. It takes time and effort to get this one even close to center. As you can imagine I’m not crazy about sanding the ring to achieve better focus.

Pros:

Very low Vf. Longer runtime at top output.
Higher candela than dedomed xp-g2 without the hassle of dedoming and tint shift.
Throws further than any single cell C8 I’ve seen to date.

Cons:

A little too white for my taste.
Needs a custom centering ring.

As a comparison, the same light with XPL-HI V3 3A direct driven at 5 amps gives me 650 meters throw. A 2S dedomed XP-G2 driven at 5.1 amps shows just under 800 meters.

Are those numbers tail reading or what you have set in the LD-4 driver firmware?

Tail reading with a uni-t clamp meter. I’m reading .25 amps below what the driver is set at.

Possible solution for using a bigger reflector insulation gasket/centering ring with a smaller emitter: glue it using a slow curing glue. I've been succesful using Zhanlida B-6000 transparent glue to attach XM/XHP50 centering rings over 3535 emitters, for example.

Did you say the tint of these Osram emitters is angry blue?

Cheers ^:)

Those are some sweet numbers, mine does only 120kCd @ 4.5A (LD-B4 + MOSLED 3030 MCPCB).
I’ll have to try a 3D printed centering ring to see if I can focus the LED better

Those numbers are at turn on, right?
There’s no way you’re getting peak performance at 5.5A after several minutes of runtime.

My UNI-T clamp meter usually reads too low, so I believe currents are closer to UI set values, which means peak is actually at ~5.7Amps, just like I measured.

What meter is it?
Have you compared it to a fluke?
If it’s a 210E then I would trust the clamp meter much more than the driver UI settings.

Yes, 210E. The thing is, I test every driver before shipping ,one of tests is current check (with Rigol DP811 PSU which has 0.1% current reading accuracy), for ex. 1.20A medium is in 1.17-1.22A range for 95% of drivers. Similar applies to other modes, but due to test connectors limitations I can check high mode for 3Amp driver versions.

Anyway, his numbers are pretty close to what I measured on bench test, peak is definitely higher than what djozz' test shows, and conclusion was that djozz' test rig has some additional thermal resistance which is not negligible, which causes lower peak outputs on higher power LEDs.

EDIT: just tested my 210E clamp meter with Rigol DP811 which confirms it's not that great for current measuring: at 5.00A CC set on PSU, it reads 4.88A, at 6.00A CC it reads 5.87A, at 7.00A CC it reads 6.82A!

Error is quite big, and zero-ing doesn't help at all since offset it is already +-0.01A during measurements.

Predictable and cancelled out if multiplying by ((5 ÷ 4.88) + (6 ÷ 5.87) + (7 ÷ 6.82)) ÷ 3 = 1.024376544492, O:) at least in your given case.

Cheers :-)

I also don’t see any issue using WF1mm with FET DD single 18650 setup.
As you said we just have to add more resistance like longer thinner wires, no spring bypass, low current batteries…

For example FET DD setup will work this way(with low current battery) 4.2V > 3.5V = 5.7A > 3.5A

Proportional current drop happens when we turn on the light so no freaking chance of overcooking the led and very constant performance on lux meter to… :+1: Yes! Lux performance should not drastically drop… It will not drop even 10% from 5.7A-5A…

Since led has very constant performance we will not notice significant performance drop even up to 3.5V/3.5A of battery discharge, and even beyond that mark… FET DD cools itself naturally when performance starts dropping. So what is bad in that? :slight_smile:

So even with unregulated setup like WF1mm + FET DD can work just fine.

Now since I also use Uni-T clamp meter it seems that current measurement are bit lower than originally measured on UNI-T clamp meter but that does not changes anything… In fact… Even Better!

And then you go on describing the somewhat ambiguous solution to resolve the issues…
I mean, you choose to over drive the LED up to 5.5.Amperes on a freshly charged cell, which doesn’t even add output anymore.

Sorry, but i just don’t get it.
It’s not as if there are no proper CC drivers out there.

Nothing against proper CC drivers but nothing bad with FET DD either.

5.5A with constant and proportional current drop like in FET DD setup is not overdrive. It is just fine… So natural current drop with FET DD also means less temperature stress plus FET DD does not generate any heat on driver board while CC linear does generate?

Where can I get a 21 mm or 28 mm CC driver at 5.5 amps running decent e-switch firmware like NarsilM or Anduril with as low, or lower parasitic drain? I do really want to know because I can't keep up with all the goin's on.

I'm confused because since when is a 17 mm power switch driver the only one we need? Granted, it's the most popular but for my usage, it's still in the small minority of flashlights I have or am interested in.

I have (2) 2S 3v17mm 4-4.5amp Mtn. Max drivers and a 22mm 2S 3v 5.5amp Mtn.Max driver I’m looking for a Push Button Host(s) for…any Ideas?
