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

LOL, in this case what you see is not what you get, both leds work perfectly fine. That XP-G2 is not broke, in fact it happily did 235 kcd in my mini-GT. And the mini-GT is to blame for both leds, its centering ring is so tight in the reflector that the twisting action of the bezel when opening/closing it already sheared off two leds and cracked that PM1 led.

OK that also sounds logical :slight_smile: Except that decisive pic of g2 with broken wire which in fact is not broken.

“Wounded and still working” :+1:

Sounds like the 7135 died.

If the switch-led report is correct, the led still failed to light up while the ramp was well into the section that the FET was used (2 blinks after halting the ramp up). In that case there’s more to it than a dying 7135.

Those 7135 chips can handle some low voltage btw, I have made an infrared sk68 once (working voltage around 1.8V) with a 8x7135 driver that functioned fine with the 8 chips all burning off close to 2 Volts (I did take care of a good heat path for the chips).

djozz, I just noticed something about your test. You tested the XP-G2 S4 2B with dome on. De-Domed it only goes to 1100lm according to koef3’s test. You numbers of the new Osram are very close to his of the Q8WP, both LEDs are much better than the XP-G2 de-domed.

6.5A seems to be about the sweet spot for the KW CSLPM1-TG (white2 as vinh calls it). I wouldn’t go above that when driving it with a buck driver inside a light that heats up.

I did comment under the graph that the XP-G2 S4 2B test was tested with dome on, and also included that the PM1 clearly outperforms the dedomed version that puts out 10% less.

I must have missed that :person_facepalming: :+1:

I just found some info regarding the luminance of these two LEDs which allows us to calucate the luminance value at any current based on the lumens:

CSLNM1.TG: 108cd, 325lm, 1,0609mm2 => 101,8cd/mm2 => 0,313cd/mm2 per lumen

CSLPM1.TG: 171cd, 515lm, 1,9875mm2 => 86cd/mm2 => 0,167cd/mm2 per lumen

Am I the only one person here that have dizziness of all that numbers and names like clsmngt1tuturbo etc. ?

It is confusing, Osram doesn’t have good names for them.
We basically have a 1mm^2 white flat, 2mm^2 white flat, and the boost HX which is just a bigger version of the 2mm^2 white flat.

I really don’t know how I am getting 400 plus kcd in Brinyte B158? Magic? :slight_smile: Bad lux meter which usually under reads dedomed XP-G2 S4 2B with greenish tint (confirmed by you) is possible reason since white flat 1mm is more blueish?

So if B158 goes from 330kcd(g2) to 430kcd(WF1mm) so that is 30%? Yesterday I sold one with same numbers… Same applies for Mitko Super thrower(430kcd! )…

Looks brighter. Throws further in a night…? Strange indeed…

Boost HX I like that name because it relaxes my brain.

Very confusing, but liked KW CSLPM1.TG – 2mm2 :person_facepalming: a lot in C8+.

Is there any reasonable 60-70mm reflector or aspheric still in production that isn’t like $125+?

I did see this which looks like a slightly modified version of some other generic lights:

So I put a 2mm² version in my Amutorch JM70.
I don’t trust my intensity numbers, but at 5m my “ceilingbounce” app says :
Before (XP-L HI) : 270kCd
After (CSLPM1.TG) : 555kCD ?!
Same distance, same phone, same all except for the LED… awesome !

I also put a 1mm² in my Cometa :
Before (FET driver + XP-L HI) 200 kCd
After (2,8A 8*7135 Biscotti driver + CSLNM1.TG) : 280kCd

EDIT : My B158B now rocks an 1mm² one too, and a 2,8A Biscotti driver : 345kCd !

High current is not required to get some serious throw with this LED :smiley:

Seem that you managed to pump it up 105,56 % footballfields.
I modded my C8 up 80,88 % Convoy C8+ New look for an old favorite - #144 by Talpa
This is with calibrated luxmeter.

can i help you with something for buy ?

Makes me want to buy more 1mm2 white flat.

I don’t know what luxmeter you use but your results are somewhat closer to mine first redneck test(you even got slightly higher results than myself)…

For me B158 goes 430kcd with 5.5 5.8A current draw and when it falls somewhere at 3A(fet driver) it is equalized in performance with de domed G2 s4 2b(driven at 4.7A I have 330kcd in B158 with g2).

For bigger host like SR95S UT of mine that measures to have Vf of 3.28v(I didn’t measure current but should be around 4.5A according to djozz’s graph), BLF GT heat up faster than my mod when I hold them left and right high on my shoulders for ten minutes or so. I think it should be fine for big host to up the current to 5A.
