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

Enderman the God has made us two hands :slight_smile: . Zoomie light ain’t PCP air rifle so softer kind of orings in flashlight is just enough. They don’t have to be made out of harder materials and to snugly fitted so they can enable air pressure loos during focusing action while they will still easily maintain waterproof level. So it does not make me concerned even tiny bit… Everything is like it should be. There is no other way…

And did you missed out 24 hours test in a bucket of water? Is that not enough? There is also thread in CPF and few tube videos with waterproof test of these zoomies if you don’t trust me.

So if you want diving light buy a diving light(there are 80% of nation that won’t dive) but if you want regular waterproof zoomie that can be easily achieved and without any fuss and talking about that and reflector lights should certainly not be considered as only good and reliable waterproof lights only because of totally untrue waterproof failure stigma on zoomie lights.

Even that “bad” one handed action, push-pull non waterproof zoomies will withstand heavy rain, drop in a puddle of water etc… So they are more than waterproof for most EDC carry tasks.

A lot here depends on use. In your use 2-handed zooming is fine - and that’s fine. I’m with Enderman in finding it undesirable. Actually for my use it’s a deal breaker because what I love about zoomies is how slight hand movements make the focus follow my eyes. For that to work zooming must be very fast which doesn’t work at all with twisty zoomies and works badly with push-pull ones that have thick o-rings.
So…not all zoomie uses are the same and not all waterproofing attempt works equally well for all cases.

Not sure if you’ve ever used a led lenser zoomie, but the one-handed focusing is far superior to any kind of twist focus.
Instantly focus or unfocus the light while you carry or are doing something with your other hand.

Also, your little water bucket test will of course pass, the real test is when you have 1 or 2m of water pressure on top.
We’re not talking about 30m+ diving here, just the kind of pressure you get if it falls in a pool or gets sprayed with a water hose.
Much more pressure than a few centimeters of water in a bucket.

Put together a c8+ with 21700 bat and 5400k flat white 2mm(I think its called m21a)

Very nice throwy beam but more usable than flat white 1mm.
Does heat up fast with stock 4 mode 6amp driver.

Still waiting for ss bezel…

weight is little to high for edc. Normal c8+ is better.

Post #1000!

Did you use a centering and and where did you get it? MTN is out of stock

I got mine on the Convoy AliExpress store

Oh thanks found it, I was searching with the wrong keywords, centering ring and spacer and it was “gasket”

I also put together a C8 with 2mm WF a bit ago using convoy’s configurable linear driver. Did ~180kcd at the max ~7.5A.

As far as centering rings what I have done is just glue the XP or XM centering ring down on the MCPCB in the correct location. I find I can get it nearly perfect just by eye. I have even been known to use double sided tape in a pinch. :innocent:

Gluing it is better than using the 3030 gasket as it’s not always perfectly centered. Love the centering rings that are cut precisely for the led, not just a circle.

Nice to know. As it happened with my M1 with customized weird ramping firmware driver (current-limited to 5A theoretical by replacing the sense resistor stack), where the effective output current was a bit less at ≈4.75A. I also had to custom file a 3535 gasket back then, and ended up obtaining 101+Kcd on a cold start.

I am to build an M2 now, too. Reflector area wise, the M2 is 81.169% the surface of the M1. So, your build looks to be right as it is.

What driver did you use?

How is that mcpcb being held down?

. Mtn.SRK 7135 driver 5.2amps at the LED.

. Thermal paste- Clamped-Thermal glue (very little)

. SBT90.2 and a mod’d Q8 driver is going to replace it soon…

Thank you

Installed the 2mm white flat into my L21A and get 1.35km at 1200 lumens ANSI. That’s impressive

Are you sure about the reflector size relationship between the m1 and m2? I was always under the impression they were much closer in ID/effective area…

Pretty sure JaredM, check my latest post in the Convoy thread.

I measure 25.6mm internal diameter for my M2. I believe the M1 is ~1mm larger. So that would mean about ~7% more area. Could you take an internal diameter measurement of the M1 please?

Nice results!
I have a L21A with 2mm as well.
How is your focusing and what driver did you use?
