Since we have 2 software related questions, stepdown and lvp, I sent a PM to Toykeeper with this thread link. Hopefully she will post here or answer me and I’ll relay here. Now we wait.

I found out that the LVP goes by the same voltage it blinks out (the MCU blinks the voltage it sees and LVP is controlled by the MCU). So if the voltage reads a bit lower than actual, LVP will activate a bit sooner.

I dont think there is much in the way of fixing the thermal stepdown behavior. On some driver designs the stepdown works well and on others it acts not so great.

Has anyone tried setting the top of the ramp a tiny bit higher or lower and then checked how the thermal stepdown responds? Maybe it will change.

I have tried to change the max ramp level up and down and no matter the level it starts to step down after few seconds, something that i noticed is that in Lower voltage 3.8V and down of the battery this isn’t happening, another case is when i ramp a few times it starts to sustain the max ramp level. So i don’t have an idea where exactly is the problem.

Man, I have no idea. I’ve never heard of this happening. Toykeeper doesnt know either and she’s the one who wrote Anduril.

Is the light usable or is it always ramping down?

Have you tried setting the stepdown temp to it’s highest level?

[oweban]

Have you calibrated the temperature?

Hi guys I wanted to address the most common issues with this light and some solutions I found, but I decided not to spam freemes thread so much so I made a new one for technical issues with this light:

ASTROLUX MF01 Mini - common issues thread

Hi everyone I want to post some info here about the most common issues with these MINIs and some solutions how to fix them. 1. Incorrect Voltage measurement and LVP kicking in I asked Lexel about the problems with voltage measurement (since he is the one who designed the board) and he was very kind in walking me through the problem and showing me a solution. Some of these MINIs measure the voltage bang on, some measure up to 0.4V less. If they measure the voltage to be 0.3V less than it really…

Its based on info I got from Lexel and ToyKeeper. It adresses thinks like LVP, incorrect voltage measurement and the light throttling down from max ramp.

And where does one buy such a UCL lens?

Tint on the 4000K is worse than I expected. Now I’m torn between trying to lower the DUV by swapping three leds to 2700K SST-20’s or swapping all to 4000K SW40 219B’s.

Thanks. I hope they are willing to send a lens in a regular envelope for 4 bucks to the EU…

[middle_age_man]

What size lens does the MF01 mini take? I have one on the way (SST-20 4000k).

40.05mm x 1.90mm is what I bought

I tested the 2700K SST-20 in the E07 and I really like the tint. If mixed with the 4000K FD2, it should result in a very rosy tint.

Depending on the batch of SW40 you get, it might not even be as rosy as the SST-20 FD2 at turbo.

[Ryzbor]

The target would be to get a acceptable (= zero duv or below) 200lm mode. I see the 2700K is in the BBL at that power, but the FD2 quite high above it.

Actually I don’t like rosiness at 4000K but prefer a neutral- slightly rosy tint.

[SKV89]

From my experience 4000K on the BBL is a little yellowish for my liking. 4000K at DUV –0.002 looks much more neutral. 4000K with DUV of –0.003 to –0.004 for me seems perfect neutral white because I don’t see any yellow or pink unless I compare it side by side with another light of different tint. Maybe it’s my eyes or the ambient environment I’m in.

Can the battery sleeve adapters be gotten somewhere so that other cells can be used in the light
TIA

I just cut out, or rip out, a section of cardboard box to help center a smaller battery. If you want plastic ones, just check Aliexpress.

What other cells do you need?

I saw somewhere it could use 21700’s and 18650’s. I did not know there was a code for discount could I have one please?

Most unprotected 26650, 21700, and 18650 are supported.

Anyone know of a coupon code I could use for the mini copper?

[twisted_raven]

40mm x 1.9mm ucl lens fits the mf01 mini?

Does anyone know how to turn the secondary brighter? On mine they are so dim I can barely see that they are on. I took the bezel off and looked at the pots but I don’t see how to adjust them, looks like a cage covers them preventing them from being adjusted.
