Sign me up, I had one with 219Bs in my cart before Simon pulled em out.
Also - 519A emitters in S2+ hosts please. A shorty S2+ with a 519A is a tantalizing idea.
Simon, did you ever get a round to do some measurements? If not, I’m assuming you’re enjoying a well deserved vacation 
+1
Would love to have a high CRI alternative to the LH351D in various temperatures. Already have too many LH351Ds and I’m done with SST-20, which is too narrow beam and only 2700 and 4000K (low CRI of colder ones is a no go).
I remember when Simon released the driver first red W1 Osram, and iirc it was made more so for the lower voltage frequency of that LED not necessarily the low amps.
Couldn't a red W2 be used with 8*7135 more efficiently? I have used a couple, but I've never looked up what they're Vf is.
2000k gt fc40 ?! Sign me up!
Me too!
One for me too, with the ability to run without the battery inside (just using the USB cable), pretty please
Yes! Especially the USB!
By the way today I burn out my FC-40 driver today when tried to put it from M21C to new kaidomain host. Most interesting of that driver is that it is based of MP3431 boost driver IC which is very good. Most of Convoy 6V driver for XHP70.2 and XHP50.2 are TPS61088 based.
Speaking of drivers, when cleaning contact surfaces in a B35AM light, I found that the driver contains an IC with the identification sanded off. Not what I expected to find in a Convoy light and I wasn’t looking for it either. It just stood out due to the roomlight reflecting differently, so it peeked my interest.
Wellp, they didn’t want you peeking. 
Then don’t sand it so it doesn’t look different from the rest! It’s the good old if somebody tells you not to do something, you really want to do exactly that 
I know you know the feeling
Main ic like MCU or main DC/DC converter are not laser trimmed like this. That it’s not IC, it is input reverse protection transistor maybe p-mosfet.
Dear Simon,
whenever I receive a new Convoy flashlight, I select mode group #10: 1 , 10, 35 , 100.
I’d really like to see a group like this: 1 , 10, 35 , 60, 100 %.
Even better: 1 , 10, 35 , 60 ——-> hold half-click/tap for 100 % from every level ——-> hold half-click/tap to return to previous level.
I like the idea about the spacing.
But I would really love to see click and hold from off for moonlight. Double click from off for turbo, this for me would make the UI perfect for my needs.
Sounds kinda like the Zebralight UI
I would like something like this too, but understand that this mode spacing was developed many years ago based upon typical human-eye perception of light. It varies upon eyes and situations but generally bumping up double-% or so doesn’t look much brighter at all to most eyes and to some eyes it looks pretty much the same. Triple is noticeable. Simon and many manufacturers have kind of stuck to that minimum rule of thumb. For those simple drivers you can’t really do what you’re asking, but of course other driver designs can do all kinds of things…which brings us to side e-switches or tube signal rear switch designs like FW3A, etc.
I like the option for something like a 70% or 80% because although it may not visually be a huge difference from 50% or 100%, for the way I most often use my lights it does in fact put a little more lumens where I can use them and it also cuts back on energy consumption and heat. Ramping firmware (good ramping firmware) can get you exactly where you want to be, and the smart features baked into something like the Anduril ramping are better still. If Simon never wants to do this in his drivers you can always have Richard at Mountain Electronics flash a mode sequence that you like with some other options as well.
The new Convoy M21F features an e-switch which can do a lot of things, but I prefer a simple and robust tail-switch. The design of the Lumintop B01 and D2 is simple yet excellent: low - medium - high - double click for turbo (100 %).
To my mind, the impact of the Weber–Fechner law should not be exaggerated. The difference between 60 % and 100 % is clearly visible.
1 , 10, 35 , 60, 100 %.
Why 60 ? Because it’s very close to the highest level of output that can be sustained without cooling the flashlight. On the other hand, energy consumption at 60 is way less than on 100 %, so you’ll get more bang for the buck.
When you can’t save the flashlight from being cooled, like when riding a bicycle, there is no way to adjust it to around 60 . You are left with two options: 35 (too low sometimes) or 100 % (too much energy consumption if used for more than just a couple of minutes). I just want more flexibility but still keep things quite simple.
Not what your looking for exactly, but have you used the convoy ramping driver from the c8+? It allows three custom set modes essentially. I use mine like your describing roughly. Turns on in “60%” (about as close to only just visibly dimmer than full using the ramping), other two modes accessible via double or triple click are quite low and full.
Means I get lots of light with manageable heat and energy use for most use, with ready access to a little bit more if I need it, and a dimmer mode for standing round o r closer tasks.
I wonder if Simon is gonna offer the B35AM in the C8+.
Getting excited about Simon’s store reopening soon!
