Do you have a spare split ring lying around in your house?
Ordered mine , thank you. Any drawbacks anyone can think of using molicel 26a’s in this? Had good performance out of the couple I have. Figure I might run with more for this and the blf lantern.
Interested.
I would suggest you something like this: https://www.aliexpress.com/af/camera-screw-d%25252dring-release.html?SearchText=camera+screw+d%252dring+release
But please take one with the a screw which is as short as possible, because in the tripod screw hole is not much room.
I had several, but I guess they were all too big, because all I achieved was scratching the light trying to get them on. I ended up taking apart the strap that came with it, and cutting the ends at an angle before burning. EDIT: I was going to post a pic from imgur but can’t get it to work. Try this link

Very much interested 
I am interested in a Blue MF01S 4000k or 5000k. The blue seems to be completely out of stock. Will more be added?
From August 2, 2019
Once they are gone, they are not making more.
Is the coupon still active? I get “This coupon only applies to specific products” when I try to use it. I’m getting into this late but would love to pick one up.
I guess you meant US warehouse. There are a couple of Blue 5000k from CN warehouse.
Hi does somebody measured the lumen output of 5000k version? Because I saw this video https://www.youtube.com/watch?v=J3KoRw0gLaU and the reviewer said that the 5000k version is 11 610 lumens. But it should have about 14 000. The 4000k should have about 11 000. I saw the other review from Flashaholics who had 6500k version and he measured over 16 000 lumens at startup. So I am confused.
Our coupons only work for CN warehouse. [quote=LTC]

- Cool white LEDs would definitely yield the higher output than neutral and warm white LEDs.
- It is not easy to take accurate readings for beyond 8K lumens without laboratory grade equipment.
- Battery does make a difference in peak output.
A couple of points.
This new MF01S uses a FET driver, so output is directly effected by the battery you use. I’m not sure what battery Matt used to measure 11,610, so I will ask him. I think he used protected Acebeam cells. Protected cells always add resistance and measure lower. I’m sure he will measure higher output with unprotected high drain cells. His lumen tube looks well designed and it’s using good calibration sources. I trust his measurements.
The Flashoholics guy doesn’t know much about measuring output and is a total jerk. He made his own light box after crapping all over the PVC tube type and has no calibration source. The output at start up is not even how it’s rated. You need to wait 30 seconds (if possible). I don’t trust his measurements at all regardless if they seem close or not.
Regarding the grit/sand/gravel inside the MF01S box — I also noticed those on mine.
I cleaned up the grit from the foam inside the box. However, when I checked again another time, there’s a few more grit inside — it turns out those “grit” actually come from the “desiccant silica gel” (or something equivalent). The small ‘bag/pouch’ of “silica/grit” were spilling out since the pouch looks to be punctured.
I wonder if it could be the same thing in yours.
Maybe that could be batteries but I don´t know if there will be so drastic difference between two types of batteries. But maybe yes. I am still waiting for my flashlight so I will see. I read that we could use flat top batteries too right?
I’m interested in the code if it’s still available
Code still available?
