I’ve modded about 50 of these, if you get stuck feel free to PM me for advice.
Mitko, looks like a nice rig!
Just RMA it should not do the whining

WOW, thanks 18sixfifty! Sure will do!
OK here we go, how I got a free SRK host
After reading here on the forum I was intrigued by that nice looking torch I see at the top of every page here and I discovered it is called SRK.
I read about them an found some topics with pictures of the components.
I looked on AliExpres for the cheapest I could find with 4 emitters AND having pictures that showed the same stuff as described here on the forum.
I forcussed on the driverboard, looking for the three brass rings, the button having 4 small dimples, the tailcap having a swooshlike shape on the decorative centre thingy and the name SkyRayKing with TM behind SkyRay.
If a seller had 1 of these not on the productpage or it was different I skipped that one.
SO in came the first “SRK”
And the pics were not showing the product I received.
I contacted the seller and showed him these:
he did not respond and I started a dispute.
I merged some pics because when starting a dispute only 3 pics can be provided (and/or a 200meg video)
BEWARE, there is an option “not a genuine product”, when reading through the terms and conditions of AliExpress I have read that WHEN A SELLER GIVES the genuine article garantee you will be refunded if it is not genuine. I read between the lines here and figured that without such garantee a dispute would be futile. So (as with the fake Convoy C8) I put the dispute in “model not as described”.
When you start the dispute you can choose your desired resolution, I choose full refund and not shipping back (since shipping is expensive)
I wrote a little text stating that without the provided pictures and inforation I would not have bought it.
About 90 minutes after the opening of the dispute the seller agreed with my resolution (as with the fake Convoy C8)
So for me this worked out fine, and it is the reason I buy from AliExpress.
Another one wth 3 LEDs in underway and I will check it for the same details, if needed starting another dispute.
There are about 5 in the low (sub $22,- pricerange) that have the right parts on the pics, having free shipping and thus qualify for me to order.
There must be a connextion between different sellers, when I first checked before the dispute there were more, I had them saved. But now the pics with goo parts are either removed or changed into showing a different driver board. This happend yesterday right after the dispute.
What I like about AliExpres is that in the orderdetails ffor every order a snapshot of the product page can be viewed, this snapshot is how the productpage was at the time you ordered, so changing pictures or specs will have no effect on a possible dispute.
Right now I am axiously awaiting response from RMM for the DIY parts 
Thanks for sharing your experience, and especially for this picture! That’s very informative (and disappointing that a multi-cell, multi-emitter can’t match a decent C8). Very helpful!

Wow, I missed that post with the fake SRK pics.
That is the worst SRK I have seen to date. The fake SRK's I've come across at least had okay output for ~$25.
Can we get a more focused picture of the emitters? They actually look like they might be XPE instead of XPG but it's just a little to blurry for me to tell.
Yeah, those emitters look like they are XP-E, and given the tint, probably LatticeBright fakes. Definitely not XM-L as advertised. Not sure what the “XGP” is they have printed on the PCB…
Let me try to get some better pics of the thing and also of the light it produces.
These pics were for the dispute so focussed on the difference of the advertised product.
I wil be back in this thread
OK here goes, it is all about distance since the SR floods a lot more.
Here are some pictures of the light produces, text is below each pic
The central beam is about 4 meters high, the lights are standing at about 1 meter from the ground.
The first two light pics are made with the flashlight in the centre, for the two after that I had to move the flashlights a little bit to be able to get in in the pictures, and they were standing about 14 cm closer to the ceiling.

the living kitchen control pic, the spec of light on the left is a tower of the castle about 800 meters away that is illminatd till 23h.

Now the hardest part, the LEDS, man oh man, tried with magnify glasses, the cam just would not focus, trief with different settings, and sorry, this is the best I cold do.
I did not scale these down so hopefully it is doable to see what these are
Definitely LatticeBright (or other) counterfeit XM-L clones.
Thanks! These two shots are very informative too. Hotspot on the SRK is not impressive, but there’s lots of difference in the spill (not surprising). Any mods at all to this SRK yet? Any planned?
Yes modding is the idea, right now it is as it came. (And I really like it because of the flood so I use it the most, even in this unmodded fake cree configuration it is very useful ;))
2 DIY version 1 sets from RMM are in
So we start with that and new leds and in the process we want to find a solution for the cooling (how to get the heat away from the LED lights into the chunk of alu it is made from)
Then do about the same with version 2 because there are several SRKs in transit to us.
We being my son (11) and me, both learning soldering and about electrics together.
Sounds great - have fun! My kids are still toddlers, but I’m looking forward to doing projects like this with them someday.
And good to know it’s still a useful throwy light - I’ve seen a few for ~$20 and been very tempted! But right now all my 18650’s are flat tops, so I’d need new cells too. And assuming I avoid anything with “fire” in the name, that’d cost more than the light! I’ll see how I do with a few simpler mods first, and then maybe tackle one of these.
Yeah we are looking forward to start!
And just now an idea popped up about the cooling
I sure am a newbie when it comes to flashlights BUT I know a thing of two about computers and have build many.
Cooling was a big issue and I have used watercooling and air. One type I never tried, oil. It does not conduct electricity but heat it will conduct.
So I will make the area above the driver and below the LED shelf waterproof, attach some heatsinks to the bottom of the LED shelf and fill the whole space with oil to get the heat to the chunk of alu that makes up the housing.
Poses some challenges but an oil cooled torch just sounds too cool not to try 
Definitely! Share when you do!
A quick search yielded this very interesting thread… Didn’t find a conclusion or final product, but it’s an interesting read!
