I belive the sales of M1 are small because there are no any emitter options.
The only option now is xpl-hi. I would be interested in some hi-cri options like sst20 or lh351d or an osram emitter for a small throwy flashlight.
I think its a very nice design with more thermal mass and throw than a s2+ but not as bulky as c8+.
There are so many emitter options for the bigger 21700 M21b but none for the 18650 M1. Same thing was with T2

Simon, are you going to sell the SFT-40 LED and if so when will it be available?

I’ve asked this recently and Simon said it will be soon. Few weeks or less. I’m waiting for this LED and the SFT-70 with much anticipation. I plan on doing output testing immediately once I receive them and posting results comparing to HX, SST40, and others.

Will the C8+ 18350 tube work with the original C8?
Is the thread form of the C8+ the same as the original C8?

My supplier first said “early April”, then “mid-April”, and now told me “late April”.Oh ,damn…. I am very melancholy.

I am very hesitant.
Because more and more buyers will choose 21700 flashlight

Simon when for a 3A version of your 17mm mosfet linear driver?
I like them,single side,efficiency than AMC based

A sense resistor mod should allow 3A to be easily achieved.

I mentioned that in another thread. A 3A version would be compatible with most LEDs, and single sided drivers fit the pill in an S2+ using the retaining ring. Simon has an updated 3A driver but it’s the same 7135×8 driver from before with the newer 12 group firmware.

I agree,glad I’m not alone.
From a Mosfet driver 3A is a good amount of current for many single Led 3535 size,where 5A mean many more heat.
Yes single sides perfect to be screwed on S2+ pill.
And the efficiency Is better at lower levels current than AMC
Hope to buy It soon

This is 3A driver ,it has constant current and temp control. how about this?

Seem different layout with a lot of resistors, is affordable? Was enough get 3A by change the R010 sense resistor from the stock 3V 5A Driver?

Wish It came also with “Biscotti” FW

If it takes regular 26650s, one nice thing to do (especially with those long springs) would be to make the tube just a bit longer so that it could take the new 26800s.

Maybe I’m whining, but it seems to me that the black wire (minus the led) is dangerously close to the edge. In your photo you can even see that the edge of the pcb (battery minus) is connected to the led minus. I’m not saying it is so, but this is how it looks.
Needless to say, it can burn the led, because it will get too much current (direct drive)?

You say it yourself; edge is the ground plane. Black wire and edge are connected by copper under the silk screen.

Typically the battery + is directly connected to the LED anode. If the black wire shorted to the edge ring (which is physically connected to the battery -) the would the LED not short directly across the cell, bypassing the driver entirely?

Guess it depends on where the MOSFET is located in the circuit.

Do the new 3A drivers have a constant frequency or alternating frequency strobe?

Where?

They are connected from the outside with a small amount of tin. Look on the photo.

Does a single-cell driver exist for the L6 that is compatible with the new FC40 LED?

But these are using what firmware? Plain old 4 mode with memory that can’t be disabled? A single sided programmable 3A driver would be perfect for a lot of host/LED combinations.

L6 driver is 30 mm, right?

Just a personal proposal
it is possible to add groups modes on the FW for this 3A driver and others, like:
0.1% 1% 10% 40% 100%.
Where 40% mean~1.2A,good for run continuos on S2+
and these groups for limit max current of all type drivers
0.1% 1% 10% 25% 50%
0.1% 1% 10% 30% 60%
0.1% 1% 10% 35% 70%,
Maybe it give more flexibility according to the type of driver, Led and host used

Thanks, but I was asking about the strobe mode, not about PWM.

Just discovered today that the Convoy C8+ is now available in four new colors: red, violet, orange and green. I’m going to need a third C8+. Innocent
