Yes, I already triple-checked contacts and reversed cell holder more times but nothing… Anyway, I should receive the new SAMSUNG 30Q next week and I will confirm if it is a cell issue (I hope so…)
Thank you
MF01 is 2S2P, so with 3A limit you have 6A total. With a 5A protection you have 10A total, which is well below requirement; Lexel measured 16A for V1 Pre production sample [Review] Astrolux MF-01 4x18650 flashlight supplied by Banggood
Has anyone modded this light with XPL-HI or XPL-HD emitters? I think with some VCT6 cells and XPL emitters this light would be a monster (if the driver would allow it).
About 6 days ago I told them that I can’t solder the leds. I received an email saying I will receive a reply in 48 hours. 6 days later…nothing. Then I told them that I’ll write a very bad review on a popular forum if the issue doesn’t get resolved immediately. Received an email in 13 hours saying they have shipped the new head.
See, you just needed to wait one more day. #nopatience #Chinesetime
Lol. Just kidding
Nichia leds are known for the trade-off between nice high CRI neutral white and high output.
I measured about the same numbers on my Nichia MF-01 V2 end of last year. I wouldn’t have noticed since it’s bright as hell anyway… but was a bit disappointed of course. Since then i sent it to Lexel in Germany for a driver swap. Now Texas Ace driver with Narsil ramping - like the Q8. Last time i measured it was over 13K lumens of pure Nichia white - with added GITD tape under the optic. That was extra cost of course… but now it really shines as it should/could have. 
I dont know. But I think you have to use a unregulated driver to tet extra output with this configuration.
Can the MF01 be run on two cells?
Yes, but power would be limited of course. You may not get turbo.
The battery carrier is 2S2P so it can use 2 or 4 cells.
mmmhhh….interesting! In the meanwhile I wait to receive new Samsugn 30Q cells, can I put 2x LG HG2 flat top to try more testing? If yes, in which configuration? :innocent:
Yes, you will have to try different combos. You have a 50/50 chance, so if your first try doesn’t work, move one of the batteries to the other slot. The batteries need to face opposite directions to put out 8v.
There is the risk of overheating / melting the springs with too hight current.
You will double the current which have to go over one springs compared to 4 batteries.
Ordered mine in XP-G3!
i have my mf01 driver replaced with narsilM from Lexel several weeks ago and i just did springs bypass and now it is making as much lumens (ceiling bounce) as my Haikelite MT09R which is at least a 14.5K lumens flashlight. just wondering Is it safe at this level for the Nichias?
I just received my modded MF01 219c with buck driver and spring bypasses on driver and battery carrier from Lexel. Ceiling bounced at immediate startup measured 1615 lux vs 1244 lux stock. For comparison, stock MT09R 4000k 80CRI measures 1640 lux and stock MT09R 5000k 70CRI measures 2170 lux. However, the MF01 lumens drop rapidly the moment you turn it on similar to the Emisar D4 whereas the MT09R can maintain lumens much steadier. I guess that is to be expected from the small size of the MF01 so temperature regulation kicks in right away. The beam on the MF01 is a large focused hotspot with very dim mild diffused spill whereas the MT09R has a slightly smaller hotspot but much larger spill for a much more practical beam pattern that I like more.
The tint on this one, which I ordered in February 20 is much rosier than the stock one I ordered in February 03 of this year. I like the rosy tint much better than greenish tint. Compared to Cree 3A tint, this is still not as rosy.
Overall I like this modded light much more than the stock MF01 and it is the only 10k+ lumen 90+ CRI light on the market. Lexel did a good job. I recommend his services.
Interested, 2nd batch
Promo code please 
I just ordered one of these with the 219s. I am a semi-retired physician and have done some Forensic work in the past. The relatively good color rendition is important. I have had some problems with Bangood previously but they ultimately took care of the problem. At this point, I have not found any problems with it. After reading about the mods combined with having also just receive the D4 with its unusual UI, I will either try and do the mod myself or send it to Lexel which might be a good idea with respect to time. I have some experience doing modificatons and building electronics…but not reflow. Anway….I like this light.
I recommend you have a professional handle it. I had it shipped to Lexel from Banggood and he worked his magic. Saves you alot of time and trouble figuring out how to do it and it’s guaranteed done right. The MF01 is glued tight so most people will not be able to open it without the proper tools. Also Lexel’s prices are very reasonable.
SKV89 Thanks. I did not know about the mods before ordering or I would have saved some time and money by doing what you did. However, if there was a problem with the light…well you know where I am going with that.
He told me that there are two different mods.
Is one of them like the D4?
What mods did you have done?
