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

Has anybody else in the US got their White Flats from LED4power yet?

It’s a Qx9920 buck controller with a Vfb of 250 mV. Lowering the sense resistance to around 60mR should give you 4A.
There is some overhead as described in p.7 of the datasheet, you’d have to measure C_off for exact values.

But I’m not sure if the FET is up to the task, can’t find anything with that marking (00A? OOA?).

I don’t see the circuitry necessary for true CC as advertised. It’s probably just a buck with the output PWMed.

I was wrong. SN6X-2X is using a 6A LD-2 driver. I’m sorry.
I am reading 5,2A at the tail (left)

4A LD-2 driver was used in a Tiablo A10G. With white flat at 3,8A I get 282KCd (right)

Just ordered one for my Uniquefire 1405. Will post results in a month :frowning: when it gets here.

Shipping time within EU is few days (from 1-10 in 95% of cases), depending on country and their post offices/customs, definitely not a month.

Mine shipped 10/22. I’m not nearly antsy yet.

So used to shipping from China. I might forget I ordered them. Ooh surprise!!! Lol

How do you know when it shipped?
Do you get an email saying it shipped?

I only got an email saying that the order is ‘complete’ 10 days ago, and haven’t heard anything since.
Hopefully that means it was sent out.

Yeah same here just the order complete email. As long as it shipped I’m cool.

So if one were to direct drive a dedomed XPG2 S4 2B and then taking the same battery (also fully charged) and direct drive the Osram KW, which would have higher lux?

:+1:

The white flat because it has much lower forward voltage.

Hmmm… Very small inductor for a 100µH…
That will probably be a bottle neck, will get hot.
Tiny FETs too… Could be okay though.
You can slap another R160 sense resistor on top of the R160’s (which are probably parallel) to up the current.

PoS driver. Its sense voltage is ridiculously high, Vsense = Idrive × Rsense = 2.8A × 0.08Ω = 224mV, which is awful. Stand aside… :facepalm:

Cheers ^:)

"Completed" means shipped, and if you chose registered mail, tracking number should be also mentioned it that mail.

Ordered 5 of them.4 are immediately going into a (jetbeam T6) with the stock driver.

I’ll post results in this thread in about 2 weeks. Anyone wanna take a guess what 4 OW,s will do in a 80mm ish T6 housing, Lux wise?

I just finished installing a the older Olsen flat black with MTN fet driver running 2P pani/3400 in a astrolux MF02. As far as hot spot intensity goes. It seems more intense then my BLF GT on a white wall 100 yards away. Going bonkers with properly centering this tiny led. Anyone wanna guess what this light will do, lux wise? once i get it properly centered? The MF02 reflecter is a fairly ringy and simply a poor quality reflector. So I’m not expecting anything amazing here.

No… Enderman is not quite right here.

The answer is it depends on used battery. Anything in Samsung INR30Q class is not good for White Flat cause they will pull from 7-8A in DD mode significantly downgrading lux performance.

With White Flat you want to stay somewhere at 5.5-5.8A current draw. So use Sany GA, LGBD1, or any other low current cell that will not pull more than 6A out of emitter.

I thought 4.5A is the sweetest?

It depends on how good your heat path is. If your reflow is done well with enough but as little as possible solder, on a DTP board that is thermally well mounted on a good heatsinked flashlight body, then 5.5A to 6A may be the sweetspot. But if everything is less perfect, this led (small die, high heat) is very finicky about that and will have its maximum performance at lower current.

bought 3 of these leds from Led4power

put one in my 2016 cometa

meters went from 800 to 1216m, it’s like a laser!!

measured 4.5A at the tail

Thanks djozz. Is there other test chart done by you or others? I think we should update first post with link or chart.
