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

Ordered some White Flat’s on saturday, and they arrived tuesday. As always in good order (kudos Neven).
Took a C8 host, an X6/X5 driver, an XR reflector (Fasttech), a Canadian cent, and a 3535 centering gasket.
The cent I needed because the reflector is circa 1mm shorter than the original one and the gasket got a djozz-micro-mod to fit the 3030 emitter. Difference is I made it black with a felt tip pen.

Let’s start by saying that I followed the budget luxmeter comparison of djozz with great interest.
So my mindset was to take the results of my 1010B luxmeter only serious when used as relative values.
Nevertheless, the meter started out at 171kCd and slowly decreased to 130-ish kCd for the C8 + Osram.
Then I put my Olight MX2UT on the line, and it scored a pretty constant 119kCd on my luxmeter.
I know that the MX2UT is rated for much more, so the outcome of my C8 + Osram must be higher too
Below is a side by side comparison of the C8 (left) and the MX2UT with dedomed XM-L (right) on full blast.

Edit: the abnormal looking hotspots are caused by the paper I shine on. It is a bit wrinkled.

I’m not familiar with that reflector. Is there an advantage over the stock C8 reflector?

Barkuti, thanks for pointing out LD25 driver. I think it is the most suitable and cheap too.
It is proven this LED will turn blue with DD driver using good cell.

I am wondering if we set the Cometa stock driver to its muggle mode that has half of Turbo as highest mode, will it be okay and not to driver it blue? I am not familiar with its stock driver.

wondering if it will survive with DD vtc6/30q on my couroui D01 with copper pill and 32mm copper pcb.

Even if it survive, its output is lowered. So why take the risk.

Could we put this led in a Maxtoch 2X shooter?

In theory, the X5/X6 muggle mode should not help because the led is still driven at the same very high current that the led can’t handle, with the PWM only switching it on/off fast. In practice, part of the why leds perform lower at too high current is heat, and that is reduced when the led is PWMed, so you will see an improvement (i.e. PWM-ing an angry blue overdriven led will in general improve the tint).
But much much better is reducing output by actually lowering the current.

Thanks for explaining. I was hoping the PWM voltage going up and down fast that LED current can’t keep up and average out at lower level instead of pulsing let’s say 6A on the LED.

The XR reflector is optimised to handle emitters with a smaller footprint and a smaller die.
Usually, emitters in de C8 have a 5050 footprint, like the good old XM-L(2).

Unfortunately the switching of the leds themselves is extremely fast, but the capacitance of the circuitry has more influence on the switching speed. You can add a capacitor to smear out the PWM, but the needed value is so high that the capacitor will be too big to fit inside your flashlight. Below is something I found on The Internet, it is an answer to a similar question, it short, our PWM speeds are way too slow to smooth the PWM current inside the led:

LED get switched on really fast. Tough to make it works without risk destroying the LED.

Has anyone got an idea how to pimp this driver to 4 amps?

Maybe this one could be another alternative to the LD25, LD29 (Convoy L2 driver), Neven's LD4A and the Convoy Biscotti driver with stacked AMCs?

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.
