That TA driver is awesome. But what is the practical max lumens setting to use on that driver that won’t step down?
Second round of beamshots - same fixed settings, WB set to daylight:
That MF-01 Nichia w TA FET/Narsil driver is a blast! :+1:
… i realize some light rain must be coming…
Anyway you slice it, the MF-01 is one awesome light.
Any discount codes left for this? I am a member over at M4DM4X’s site, but the codes there don’t work.
also, all the old codes freeme has sent months ago are now invalid. Anything left?
If so, would like the XP-G3 version, and send codes! 
Please send me a code for a MF01. Thanks. 
MF01 is out of stock right now. Chinese New Year is closing, not sure if there will be any more coming before 16th Feb.
MF01 is in stock. Please send me a code for a MF01. Thanks.
Mf01 nichia with TA driver and vtc5a’s should be 17000 lumens on startup.
I just bought one with the Nichia 219c. Thanks for setting up the GB!
Can you send me the code please?
picked mine up at the post office this morning, going to play with it tonight 
thanks freeme :+1:
Is it possible to purchase the head only? I already have a MF02 and wanted a dual head light.
I’ve only seen the MT35/MF02 head sold seperately. I haven’t seen it the other way around.
Mine tops at 13-14k with 30Qs.
Honestly it is more then enough and probably way too much considering the heat and lack of deep fins on the head.
Bangood is now selling it for $77.95 without coupon. I bought mine yesterday with the coupon though.

hiKARInoob, did you measure those values? So V2 is dimmer than V1? I just received my MF01 219c today so I’m assuming it is V2. It’s smaller than I expected and the tint is slightly less yellow the the 219c on my S42.
Ceiling bounce using the Meteor M43 as a reference. The beam profiles of M43 and MF01 are close to identical, so I believe absolute lumens are sufficiently accurate. Max output is also in concurrence with measurements of other members I’ve read.
Since V1 and V2 have identical beam, relative output is correct. So in my case V2 is slighty less bright than V1 with full cells, but V2 maintains higher output with depleting cells. Both are 219C.
I was just playing around with my new MF01 and after awhile, when I enable Turbo mode, it just turns off randomly and goes into lockout mode. I would have to hold the button 2 sec to unlock it. It happened several times. The batteries are VTC6. It’s not fully charged but the light indicator is red so that means there’s still charge in it.
Does MF01 have any protection mechanism that turns off and enters lockout mode under turbo mode when it overheats or battery voltage not enough?
Never read about it. There is thermal step down, so the light should not switch off or something. The indicator should turn red at 3.4V IIRC. And if I’m not mistaken this means at 3.7V resting voltage, if you go to turbo form there, you will have sag until 3.4V so red light turns on. This also means if you then go to a low output, voltage will rise again above 3.4V and light turns green again.
It sounds like a defect to me, but maybe freeme or anyone else knows more about this?
