This is unfortunate.. Mine should be in any day now.. i will be pretty dissappointed in this. I dont even want the xhp70 version, i just had to see the host in person and it was worth $35 for me to do that lol.
I ordered a bare xhp50.2 4000k at the same time to throw into it to see which one i like better
Honestly, once Simon is done with the new 3 volt driver, i will buy it and be swapping out that xhp70 for ...(fill in the blank) CULNM1, CSLNM1, SFT40, etc etc etc.
Ordered 8 holsters from Convoy Ali store today. Thanks, Simon for offering these. I can’t understand why it’s so hard to find decent holsters.
Ditto. His holsters are excellent. I’ve got ten of them on my flashlight battle belt. I really appreciate the velcro and snap button “closure” on the belt loop as well as the extra little elastic pockets on the sides for extra batteries.
6.4-6.5A is quite high.
I previously mentioned I got 5.4Amps (using a similar setup as what you did, and also using the same UT210E setup) - I previously just used an ordinary Liitokala Lii-40A 21700 battery (not so high-drain).
I tested again using a Samsung 40T (4.20v full-charge), and got 5.8 Amps max with UT210E. It would appear it is a 6 Amp driver used on the L21B (CSLNM1).
inhave a dozen or so from Simon, his are fantastic quality! And a great price
yea, and 6.4-6.5 makes no sense. Like Barkuti mentioned above, it should cut off at 6.0a ... unless it's an underperforming 8amp driver (I've heard that happen before too, but not this low it was more like 7.2 iirc).. but that would seem like a huge blunder- installing the 8amp driver instead of the 5amp driver??
No.
Here are the KW CSLNM1.TG (1mm², 3030 footprint) and KW CULNM1.TG (1mm², 4040 footprint) datasheets. Maximum specified currents are 3000mA for the 3030 and 3300mA for the 4040, at 25°C.
Then, here is the Reflow conditions tested of Osram KW CSLNM1-KW (White Flat 1mm2) thread by djozz. In such a detailed test, all of the 9 emitters' peak output hovered between a little bit above 5, and a hair above 5.5A. With this information in mind, it can be easily understood that driving it above 5A is absolutely unnecessary.
Best performance between 5.8 and 6 amps? That's what luminarium iaculator said in his own review, where he also “found” peak performance at 10A :???: for the KW CSLPM1.TG. In my experience, though, these claims are incorrect. You can see the djozz test. Also, I found the KW CSLPM1.TG (2mm², 3030, first units from led4power) to be better driven at just ≈6.5A, where it performed better than at 8A. However, this is my particular experience, and since there are no formal tests of the 2mm² versions (as far as I know), you can take this as you like.
I did tests of 4 different Osrams: HHL532, CSLNM1, CSLPM1, and CULPM1.
1mm² are peaking around 4.75A and 2mm² are best at about 6.75A. 3030 vs 4040 doesn’t honestly seem to make a real world difference.
I’m sure instant turn-on numbers max out at up to an amp or so higher, but this is not sustainable beyond 1 or 2 seconds. I take my readings at ~5sec, or basically right after they settle in. Continuing from there, they’ll gradually fall as the heatsink warms up. Bone cold, instant startup values are highly misleading and not something you should spec a flashlight to, but they will look impressive on paper.
Simon, why have all versions of 3X21A and the SBT90 version of 4X18A been removed from your store? 4X18A SBT is one of my favorite lights.
Simon,
We talked about the possibility to made 3535 and 5050 size 3V Leds from Getian at ~1800k Cri 90 R9 >60,for me is enough.
Important would be negative Duv at very low current and blue peak as low as possible.
My M21e just arrived!
So far I like this a lot. My first ramping Convoy and I now understand the comments here about the odd speed, but I don't hate it.
The fit and finish is typical Convoy perfect. The style is nice and it's a little smaller than I thought it'd be, but not really small. Almost exact same size as Astrolux ft03 mini.
Can't wait for night. And I grabbed a 4000k xhp50 to throw in it this weekend to see the difference in throw!
Will report back once I've tried it out.
nice work Simon!
oh - Texas Shooter- my xhp70 does turn off all the way. But it does it Very Slowly. I thought it wasn't going to but it does.
I also received today my M21E 4000K version, but there is strange yellow artifacts and dot at spot. When I removed reflector and I tried to view LED beam against white wall I can’t see that yellowish “thing”. I don’t know is that normal for XHP70.2 diode at all. Because that is my first XHP70.2 light I can’t compare it to another one.
Driver is out of stock currently, it will be available after two weeks
fanrastic!
Simon, have you heard anything from Luminus about an update to the SST40, as in a gen 2 or dot2 version? Some other shops on AE claim they exist, and Luminus is very odd in how they pre-release products well before presenting documentation or public marketing. Figured you might know or could ask.
Thanks
I bought some of these in 26mm and they solved all battery recessed positive terminal issues. Now they come in 26mm, 21mm and 18mm sizes. https://www.aliexpress.com/item/1005003318519001.html
I was thinking about semi-permanently affixing them to cells with hot-melt glue as a way to improve a flat-tops vulnerability to drops, recoil, and other impact that can/does dent cells. Limited applications I’m sure, but it’s definitely something I’ll do for my gun lights and heavy-duty use lights.
Simon is on the roll
Nice! It seems the world of flashlights is getting more and more colorful. Olight, Sofirn, Acebeam and now Convoy offer more and more different colors.
It was about time!
