That looks way more high quality than I expected it to look.
I very much hope that the “LQ” Cell really has that capacity.
I will mod mine this weekend. 3x519A 5700K and probably a SFT25R 5000K.
So, today I changed the LEDs and thermal paste.
I also wanted to change the plastic lens on the thrower side, but I only have a Convoy 20x1.6mm lens here, and I need 20x1mm. Will order one from Kaidomain
I chose as I wrote 3x519A in 5700K and I tried the LMP W5050SQ3 and SFT-25R on the thrower side, but none of them made a nice looking spot, so I went the easy route and just plopped in another 519A 5700K.
I really like this little light now, might be one of my favorites!

Updating this with some additional mods I have recently done.
In total, I purchased 3 of these lights, the cheapest being ~$20. I’m glad I did because now the price is well over $30.
Below are the 3 versions I have.
- Stock (spot) + Stock (flood)
(This was later modified by replacing the spot with another stock triple. Details below) - SFT-40 (spot) + 3 x LH351D (flood)
- XHP-50 (spot) + 3 x 519A (flood)
Below are lux (ceiling bounce) measurements.
A few things to note
- Overall, outputs of spot and flood measured individually were pretty similar at all output levels, with the exception of the XHP-50 modified light which is not surprising.
- Turbo for combined spot + flood were also pretty similar
- All lights heated up pretty fast on turbo, with the 3 x LHD351D being the fastest and reaching ~150F after a few minutes. It appears there may have been some burning of the LEDs that can be seen in the photo. The others reached ~110F and stabilized after that.
Modifying a dual flood (2 x 3 LED triple).
I had two extra triple boards containing the stock 6500K LEDs, so wanted to replace the spot beam with a flood to create a dual triple.
Below are the details.

Wow great find! I wonder if the driver is the same. I think the SK-05 Pro uses a buck driver. But they freaking designed the SK-05 Pro such that you can’t get to the LEDs to do emitter swaps.
You mean the newest stock with plastic bezel right? Because i swapped sft-25r 5000k into mine, de-doomed 519a, swapped lh351d 5700k and then swapped again same 519a 5700k

Hi, i want to change spot led to osram w1 or w2.
I unscrewed the bezel, but I can’t remove the reflector, is it glued or pressed in?

Remove the o-ring and it should fall out.
See my earlier post above.

I removed the O-ring and tried to get the reflector out, but it is holding very tightly.
The flashlight is the same as the a200, but with a different inscription and button style. Maybe it is made in a different factory?
I could be seeing stuff, but it looks like it has an o-ring around the edge of the reflector?
No, it’s not there.
Maybe it just looks like that in the photo, I definitely got out o-ring.
That’s strange and definitely different from all 3 that I had. Maybe try to pry out with tweezers or slide a scalpel blade around the reflector edges?
Still, it was a little pressed in…
I had to damage it, but there was no other way to pull it out.
I made a small hole with an awl on the edge of the reflector and pulled it out.
Installed the Osram culpm1, very satisfied!
The only thing is, the overall thickness of my LED is smaller, and now the reflector sits deeper, I thought that there would be a bad clamp, so I installed the glass first, and then the o ring and pressed it with the bezel. I don’t know how correct it is, but I think that this way I got a better clamp
