At what point should culpm1 consider optimal distance? If you look the picture above, you see its beam small vs xhp35 and sbt90.2 which apparently much wider range, but those distance are fall short for this culpm1 bcos closer look it has much higher intensity of light, as in the picture, I think this light should aim further to make it clear. I still wait for more beamshot from Convoy new L21A CULPM1…
Sadly the Osram red driver is only 2.5A. It performs best at 3.5A but 3A would have been ideal….oh well
At 2.45A I get 178 lumens
At 3.5A I get 235 lumens
That’s a large difference for the red led
I’m still happy to have a driver though. At 2.45A it’s still good usable lighting up to 200m. It still gives 4 times the performance than using a red filter.
Which light are you referring to? Or this a driver Simon sells?
This entire thread is of Convoy’s torches etc, so yes, Convoy’s red Osram driver that was just added to the AliExpress store
But what about using it with SST-20DR?
I don’t have one to know but the 20DR has a max current spec of 3A so you won’t see max output with this driver
I wonder how easy it is to increase the current
Yea I understand what the thread content is, I have not seen the driver hit the store and was looking for something similar recently. Thanks for patronizing response though.
In my experience (and probably most others)- the osram LED’s have a relatively smaller “spill” area then other LEDs used for throwers like the sst40, xhp35 and sbt90… I also feel that the way the picture was taken (looks like from elevation off of the ground), that the spill area on both LEDs are not really apparent and we’re only seeing the hotspots. This new(?) osram CULPM1 should technically have the largest spill/lumen output of all the osram emitters though. I found the release of this flashlight, especially with an 8amp driver, very exciting! I’m not a huge fan of small spill throwers but I will buy this convoy, because I believe the spill area will be sufficient. I know the W2 in my KR1 has sufficient spill so this L21a host should be awesome for this LED / driver!
What is the tint on the L21A CULPM1.TG ??? It looks like a great handheld single cell thrower.
They come in CW only currently, so 5700’ish k to 6500k which is totally fine for throwers.
I mean, should CULPM1 be consider 1 Km light contender? Not below 1 km as such the sst40 I supposed so…this is consider thrower light stage two.
That would mean, the same level as the W’s which now had claimimg 2km.
Most of led that surpass 1km, it seem they ussually had a tight beam, for its reason. Its looks tight at closer but what it really matter is in the long distance. It like buggati Veron for long distance vs gtr for short drag race. You know what i mean?
I think any led could do over 1km with a big enough reflector 
All of the Osram white flat’s achieve 1km+ , the CULPM1 is the brightest white of them all. Using it in the Convoy L21A at 7A I get 1350 meters but my meter gives a higher number than others so I sell it at 1250m.
If I point it just above a hill on our farm I can see the outline of it and that’s 1300m so it’s at least that much
Sorry buddy, I replied at 3:30am, wasn’t meant to come out that way, I realized as I read it back but too tired to change it
Just ordered L21a with CULPM1 8amp ! Also ordered the m21a with CSLPM1 6a driver! By the way, my first Convoys! Can’t wait!
Convoy L21A CULPM.TG or otherwise known as the W2.1 driven at 7 amps
200 meters to the trees.
I find it curious to see many of you driving these emitters quite hard. Of course this also is because how these drivers are set at, namely the newest ∅22mm 8A switching driver (very smart choice, efficient cool running driver).
Curious because we don't really have any formal CULPM1.TG tests yet, hope they are ready soon. The CSLPM1.TG peaked at 8A, and so I wouldn't expect the CULPM1.TG to peak much above 9A. But we'll see.

Thanks for the beam shot! Makes me even more excited to receive mine seeing it in action!
And no worries about the comment, I get being tired. Definitely no need to go back and fix it :+1:
6.6A is the max in the specs and 8A - 10A pulsed.
I tested it using that ramping driver from Convoy.
- 50E 3.8v 6A = 1200 ish
- 50E for 7A = 1313
- 40T for 8A = 1318
djozz tested an early chip from hank and he said his peaked at 7A, my testing confirms it. Even at turn on it didn’t go above 1380.
That’s very disappointing that it’s not really any improvement over the cslpm1
djozz tested XP-G3 Photo Red. If SST-20-DR performs similarly to XP-G3 Photo Red (it probably does), it does not seem useful to push the LED beyond 3A.
….yes, but I’m talking about the driver which is only pushing 2.5A
