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

I secured 3 pieces, but am not sure yet where to apply them.

Thanks l4p for making these available :slight_smile:

Good idea with the drill bit. I'll have to remember that one. I have a very cheap wood reamer I've been using, but it's slow and I have to keep stopping to measure.

How do you guys clamp the gasket to stop it from moving?

My method is not wise but I just hold it in my hand (thumb and index) and do short bursts with small variable cordless drill

:open_mouth: You have stronger and/or more laceration-proof fingers than i do!

I think it might be easier because I use a step bit so it’s only ever taking off a little at a time.

Looks like Maxtoch, in addition to sourcing green and red “flats” also might have this 4040 LED in their latest thrower now. The text on the chip sure looks similar.

But proportions are not, the yellow part is 1/3 the length of the package. This looks like 3030, CSLNM1.TG.

So using the 4040 version, they may get it at 1 Mcd.

I’m afraid the distance rating may be as correct as output. Which they state to be 1200 lm.

I just got an XPro modified by Skylumen using the 2mm Whitey. When driven to only 900 lumens, the reflector in the XPro got 560k lux from the 2mm White. 1mm driven at a reasonable amount should be able to get 800k lux.

So you did get it! What are your opinions of the light itself?

The host quality is good. I can only comment on how it feels in hand, looks, and how reflector quality is. Vinh commented on the anodizing being average to good (no chips when he engraved the V54 and Fiat Lux markers on it). He commented on reflector being perfect. I too agree the reflector quality is perfect— I think it’s even better than the Acebeam T21 I have. Vinh commented on thin battery tube walls due to the larger opening for the 21700 cells, but I don’t mind.

The shape of the host itself I find great. Very smooth and ergonomic battery tube, deep fins only where they’re needed, not heavy at all. Things the T21 have on it are: stainless steel bezel, and small amount of anti-roll. The XPro has what looks to be an anti-roll element under its heat fins, but its head is so large that those never touch a surface.

The UI is a little weird. It’s a conventional forward tail clicky, but the driver checks mode memory timing when the light is on, and not off. If I remember correctly, most do it when off. If the light is turned on for 6 seconds or longer, it will retain its last used level. If the light is on for less than 6 seconds, then you turn it off for let’s say an hour, then turn it on again, it will advance to the next output level. In the same fashion, if you turn the light on and leave it on for 6 or more seconds, then rapidly turn it off and on to advance an output level, it will rather stay its last output level. I don’t have any issue with this either, but it seems to be a little quirk. The UI has 3 levels: low, might as well be turbo, and turbo. I think it would have been better to just have two levels, or have the upper two be better spaced. The default UI of the T21 on the other hand I find to just have too many levels.

XPro did not come with a holster which I found a con at first, but it comes with a very, very nice carrying pouch, which is a definite plus.

According to Vinh, the Green 1mm that came in the light wasn’t centered very well, but he didn’t seem to have too much trouble getting the beam tuned with the 2mm White to Fiax Lux standards. I’ve never seen the petals of of a corona be so defined before, it’s almost art. A lot of that probably has to do with the quality of the reflector, and the centering gasket that Maxtoch used for the 1mm Greeney, which perfectly fits the 2mm white and 1mm white. Boost HL and Boost HX would probably be harder to center.

Here’s a pic of the hotspot. Petal shapes are more defined in person. Being that this is the 2mm Whitey, the petals will be longer in one direction and shorter in the other.

Thanks for the detailed post. Maxtoch has several good reflector lights so that’s good to hear this one is no different.

Curious if the light has a pill design or an integrated shelf and what driver size. I have an 8A buck driver Lexel made that would fix your mode problems and max out a 2mm2 white flat. Now that would be “fiat lux” :slight_smile:

edit; mine is actually 6V but i’m sure he could make one 3V

I probably won’t comission Vinh to do another XPro until Boost HX comes out, but I would definitely want to use a proper buck driver for the next one. Unforonately changing drivers on the light requires the led to lose its tuning, so I decided to take the beam quality over output. The good thing is the light has no heat issues whatsoever at 900lumens.

I bought the new model Maxtoch XPro with the Osram KW CSNM.TG (1mm whitey). Iirc this is one of the only couple of lights on the market that comes stock with such an LED. Maxtoch’s numbers for it are inflated, naturally, but I can compare it to my other Maxtoch XProvn modded by Vinh with the 2mm Whitey (900 lumen, 560kcd), and Acebeam T21vn with Black Flat modded by Vinh (780 lumen, 640kcd.)

Hotspot intensity and assumed throw is longer than the 560kcd of the 2mm Whitey in the same host, and about the same as the T21vn with Black Flat (640kcd). If I had to guess, I’d say the light is being driven to around 700 lumen with 620kcd or so from factory. Emitter is ever so slightly off center, making for unbalanced petals on the corona. I don’t have experience with any reflectors larger than that of the XPro, so I don’t know how they shape the corona of beams, but I can at least say that the reflector on the XPro makes for very nice petals in the corona.

One thing that is troubling me though is the battery compatibility with the XPro host (and this is true for both XPros I have. The hosts do not work with any of the cells I have with the tailcap on. I tried Samsung 50E, with and without tailcap, and no good. Then I tried Sony VTC6 unprotected 18650s, and they work with a talcap bypass, but not with tailcap on. I also tried Acebeam protected 18650s, and they work with tailcap bypass but no tailcap. I don’t know what to make of that. The XProvn I received from Vinh worked fine with the 50Es at first, but has since refused to work with them.

The batteries are probably not making good contact in series. Would need to see the tail springs, retaining rings, driver spring, etc. Not really the thread for this but this is BLF and off topic is our specialty!

Holy crap that is a good light:

I think it’s the 50E not being good in series. Now that I think about it’s so flat that the contact in the center is almost below the insulated parts on the edge. I’ll try some solder blobs on the 50E. Button top 18650 with Vinh’s tailcap (he added a 2nd longer spring with the 1st) works.

Weltool T10 and T11 use OSRAM's 1 square mm LED
