You’re talking about how many Cd, guess?? Got from osram flatwhite?

@everydaysurvivalgear

Hey Simon have you tried to use a Flat White Osram CSLNM1.TG LED on your C8 or L2s? I found the reflectors sit to high for these super small LEDs and the focus is of. Any chance you would could make a reflector that sits lower to the MCPCB? . Without a gasket my L2 reflector doesn’t touch the MCPCB so its not low enough for these LEDs.

Actually it might be easier to make a thicker MCPCB one that is like 2.5-3mm thick. Have you come across this issue yourself?

You could make a sell a decent thrower from the L2 using a CSLNM1.TG.

Simon, is it possible to make turbo mode access only after 2 click, from any position(on or off) without memorizing it?
So it could be 0,1% - 1% - 10% - 40% and turbo after 2 click

yes ,and what driver model?

It could be in driver for SST40 and new 3*SST20

If turbo is only 1-2 min I can’t see point of memorizing it, and it would give more modes, 4 in loop and turbo when needed. Then it could be really “turbo”, not the highest mode

I definitely want it for S2+ with SST40 (and all other models too:)
Is there any estimates when it will be available?

Simon, could you please tell if there are any plans for it? I mean turbo access by two clicks (from “turned off” state as well).
I want S21A with sst40 and this feature, if possible.

I have done such a driver sample before, I am not sure if there are many people who need it, so I did not mass produce it. (and turbo only from “on” state)

I think there is a lot more people that would choose 2 clicks for turbo, than for strobe. 4 modes are ok, but with mode memory it’s annoying to turn it off at 100% and after a while, when needed low power, turn it on again in 100% and blind everyone in the whole universe. It’s annoying to cover flashlight with hand or closing eyes knowing what will happen. :weary: When last memorized mode is e.g 40% it’s not that bad to turn it on again.

And it would please some non-memory lovers

Hey simon thanks for the fast reply.
The issue is the C8 and L2 reflectors have a lip that sits on the head of the light stopping the reflector from being close enough to the MCPCB to get proper focus with these smaller LEDs.

Yea this can be addressed by making the LED sit higher or maybe by shaving the sides of the reflector down. Raising the LED is much easier but still a pain.

Even with no gasket the reflector of the L2 is above the MCPCB by a 1-2mm gives these smaller LEDs a ring effect

I sanded down the head lip under the bezel and also the bezel bottom edge to get reflector lower and no rattle. Easier than modding reflector or raising led.

You could easily raise the led by placing a empty MCPCB under the current MCPCB as a shim.
I thought id just ask Simon if the reflector could be modded to help us.

And you add an extra layer of thermal paste and aluminum and masking on MCPCB and that insulating heat transfer well. Osram generates more heat than an XP-L so you will probably ruin heat transfer and shorten led lifetime by a margin.

I was at some point thinking about using a sanded MCPCB (sand the emitter circuit side) as a shim to raise up the emitter, but I found it too thick (1.5mm)

[everydaysurvivalgear]

Even if its to high with the right gasket it should work okay? How is the beam profile? You just won’t be able to fully close the bezel.

Anyway of removing M30 temp protection?

【convoy】SFT40 5000K back in stock (sufficient)

Not necessary, posting detailed (macro) photos will do. Removing the blueish foamy thing, might help though. Here we go - not the best macro shots in the world, but a quick one while I have a few moment being left alone I know it’s not the M3 driver, and they actually look quite a bit different, so it’s probably useless for what you’re after. https://imgur.com/a/0cqCG4U my guess would be this one can you try to measure resistance? also, try to measure wi…

[oweban]

Keep in mind that’s the S11 driver! There’ll be something similar to it on the M3 driver.

[Yokiamy]

Thanks for the heads-up oweban! Totally forgot that

[andr3w]

Could anybody please tell if there is brightness stabilization in sst40 ramping driver?

[g_damian]

SST-40 8A driver is constant current, no PWM. I’m not sure what do you mean by brightness stabilization. It’s CC driver, so when battery voltage is lower than forward voltage of the LED, it delivers lower amperage.

[andr3w]

Brightness and amperage stabilization are synonyms for me here (sorry, I’m not an expert).
As far as I understood, any specific brightness mode has variable number of lumens for this case, depending on battery charge. Thank you

[ggf31416]

Because the driver doesn’t use PWM, unlike the 7135s driver, lower modes should still be stabilized if the battery voltage is high enough for that mode even if the higher modes lost regulation.

[Eneen]

What’s diameter of reflector and diameter of led triple circle? Will carclo optics do here? What’s depth of driver compartment? Wonder, if H1A driver will fit inside to drive triple in series.
If reflector is deep enough I can design 3D printed gasket-under-glass for carclo 10507, ledil satu, kai optics or even quads.

EDIT: reflector is 28.6mm x 11.1mm (answer from Simon, thank you!)
This means that there’s plenty of space and quad carclo 10622 fill fit. But for singles it’s limited to ~20mm reflectors.

Does anyone know if the S12’s bezel is stainless? Sure feels like it, giving it a bit of a play in my hand. Nice and hefty.

(Want to make sure I have the right info for review )

[Eneen]

@Simon: while improving inner diameter for 21700 is it possible that you change S21A driver size into 22mm?

[Simon_Mao]

Limited by size, the maximum diameter can only be 20mm

yes, it’s stainless steel bezel
