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

I had a D80v2 with SST40 that did that. It was due to a bad reflow of the LED from the factory.

This is extremely low considering that SST-40 has twice the die size and already has a low Vf.

Anyone here independently test a GT MICRO with the HL yet? Still can’t believe the numbers Neal claims…

Gotta say I’m kinda tempted by the Lumintop X1L . CSLPM1 / CULPM1 would be better though IMO.

Yeah I saw that at the time. I always planned on swapping the emitter so didn’t raise it. I still haven’t touched it yet though :blush:

I’ve put one into a Nitecore NEW P30 today. I’m getting a good 20% less lux than it had with the stock LED. Granted I didn’t change the driver and the LED may get driven too hard, but honestly I don’t think so. The NEW P30 claims to produce some 1000 lumens from its XP-L HI. Also it doesn’t even get warm on turbo with the Boost HX.

Also, the two Boost HX I got from Convoy were quite a surprise. I ordered them mounted on an MCPCB, and they arrived with solder and residue all over it, including on the LED and the back of the MCPCB. If I hadn’t ordered from the official Convoy store I would be 100% sure I’d received a fake.

So yeah, not a great start for me. I think I’ll stick with the 3030 Osrams.

Did you play around with the focus? Might need to sand down the centering gasket. The Boost HX needs around 8-9A to be decent, otherwise the CSLNM1 beats it. Although there’s quite a variance with the HX. At 6A I get 1300 lumens while with another I need 8A to get the same.

I did, the reflector now sits directly on the MCPCB (just like it does with the stock LED). The beam looks okay but not ultra-focused.

I doubt the NEW P30 delivers 8A but can’t measure due to my crappy DMM. But shouldn’t the Boost HX be able to keep up with an XP-L HI in throw for low currents, all other things being equal?

Not really sure. 1000 lumens from a XPL-HI, assuming V2 or V3 bin is maybe 3-4 amps or so (??). Could be dependent on the driver - might not get the same 3-4 amps on a LED with a much lower Vf, like the HX. So the amps could be a problem, plus the condition of the LED/reflow/variations, etc. Not to mention focus/optics issues.

A high amp OSRAM is probably not the best choice for this light with no driver changes.

I was outside for a bit now that it’s dark, and I’m a bit confused. I compared the NEW P30 against my modded Manker U22 V2 which I’ve measured at something above 200k lux (my lux meter doesn’t go any higher). I have to admit that the throw distance of both lights seems about equal to me, the NEW P30’s beam is significantly wider though. Both provide about equally bright illumination at about 500 meters, past which I can’t really see anything anymore anyway. I don’t have any points of reference farther than 500 meters so I’m not really sure how the comparison plays out for longer distances, the Manker sure had more reach but not in a terribly useful way.

So now I’m considering whether I just suck at measuring throw. I’ll redo it at different distances to the lux meter sometime.

Anyway, numbers aside, I’m quite happy with how the NEW P30 turned out. I hated the original beam and if nothing else, that has drastically changed for the better. So that’s ten bucks well spent.

Old school modder :sunglasses: :+1:

If Barkuti will see this he will know I am not the only one on the FET side of the world… I also have problems that certain drivers does not deliver declared amperage output… I know regulated light should be better but for my needs FET would be sufficient plus it generates zero heat on the driver board.

Yes I know it looses a lot of performance as battery drains… Especially those 8A emitters… But performance drop when used with certain types of emitters (4-5A emitters) is certainly not that noticeable with naked eye giving up decent performance “on turbo” up to 15 minutes of runtime, after that it is noticeable…

So Guys who use FET knows that they got to use turbo mode sparingly and that is it…

Ol' school for sure.... In this field, 5-10 years is like ancient history

Difference between KW CSLPM1.TG and KW CULPM1.TG?

Considering the Convoy Z1, which offers KW CSLPM1.TG 6amps or KW CULPM1.TG 8amps

They use the same die but different package. CSLPM1.TG has worse thermals, that’s why Convoy choose to run it with 2 amps less.
Overall CULPM1.TG will be brighter but hotter.

Is the CULPM1.TG better if run at the same amps? Any reason to chose CSLPM1.TG over CULPM1.TG?

How do both compare to SST40/20?

I used the CSLPM1 with the stock 6amp driver and it’s awesome. Had 4x SST40’s die instantly in an order of Z1’s so I installed these.

SST40 in a C8+ maxes out at 642m, the CULPM1 maxes out at 1002m.

SST40 = more lumens with a wider beam
Osram leds = higher intensity with a narrow beam

No idea. The culpm1 hasn’t been officially tested by anyone to compare the data between the two

Assuming equivalent bins, at low currents they would be the same. Once heat starts playing role, CULPM1.TG will be better but up to 6A the difference would be very low.

Have you been able to compare it to a Z1 with KW CULPM1.TG?

Interesting, I will have to find some beamshots to compare how narrow the two are
