✌ FREEME- ASTROLUX MF01 Mini 7*SST20 CRI95 26650 ANDÚRIL Flashlight Group Buy - $45.99

FET driver lights are not known for their consistency. :stuck_out_tongue:

I guess you are right since I see variations between E07 also. However the two MF01s that I have measured the same output.

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.

I like the more yellow FD2 bins that FF uses over the MF01’s ‘cooler more white’ 4000k bins, whatever bin that maybe. The FD2 of FF looks ‘rich yellow’ while the astrolux looks more white.

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?

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:

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.

UCL is trademark name.

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

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.

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.

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
Chris

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?
Chris

Most unprotected 26650, 21700, and 18650 are supported.

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