Yesterday i remembered that i just got some QTC, so i stuck the tiny little square on the - on the battery and screwed gently on the bottom part………and it WORKS, success 
instant seamless adjustable levels, it is like they made this light for it, i mean why else have a detachable bottom spring part on a tiny twisty light……that make no sens by itself but now :bigsmile:
It worked so well, somehow it kind of restored the modes of the driver on the 10440 when it is in lower output, it is a little tricky to get the hang of it, but now it can go instant max and the lowest moon mode i have ever seen and everything in between……
I thought i would have to build one of wight driver to get this level of control.
Now i can control the level by either the top twisty action or the bottom fine tune screw + if it press the bottom……instant max like a momentary switch :bigsmile:
So cheap & easy and so much fun
And then it was DEAD…….
:~ :_( i guess the boost driver didn’t like the power source altering its characteristics so fast, so it broke something.
But like i always say, if you are going to push the envelope failure is always an option 
So today after a good nights sleep, i opened it up again to try to figure out if the led was broken, it wasn’t :bigsmile: :party: so i stripped off all the components of the stock driver, and searched with my DMM for + & - on the top side of the driver board and found the + bat on the left pad where the coil was and - bat on the left C3 pad, so i soldered the red & black stock wire to them.
I cut of a little more of the noctigon xp16 to fit even better for more heatsinking and more room for the wires and tried to center it in the reflector this time.
It is a lot of things you have to think about that you don’t know you have think about before you do it………
And it all worked perfectly :bigsmile: Now it is direct driven from the 10440 with levels provided by the QTC and now it gets hotter than before so i guess the contact on the shelf is much better, i still need to sand of the anodizing, but this is much improved and this time i got it perfectly centered also.
Next step is trying to lower the resistance in the circuit by getting some fatter wires and instead of reusing the pcb + - connections, running it through the contact board, but not before some better heatsinking.
I still can’t almost believe how this tiny thing can produce so much light :bigsmile:
Big thanks to DBCstm Dale and djozz 2 for making me want to do it and inspiring me
