When the chargers will be sent to us? It was said that it is the beginning of march…
The AMC7135 are rated til 7V. So they can not beused for 12V LED:

Noob question: so it’s not possible to wire two 7135 chips in series or something to power a 12V led?
I have, there’s no resistor on it. Just the LEDs wired in parallel.
That is one theory ,the other is the 3 XHP35 can produce 7000 Lumen but they forgotten tu pull of 20% for reflektor/lens etc.
Then you have 5600 real OTF Lumen .
Well, Haikelite doesn’t advertise in ANSI, so it’s also possible it’s just led lumens they’re talking about. I’ve always used 15% as reflector and lens loss. So 7000 led lumens results in 6000 OTF lumens. This also equals to 2000 OTF lumens per XHP35 emitter, which is just fine.
There is one thing i can not really understand.
Haikelite produces a prototype?
And then they test it in an Ulbricht sphere?
I have read(in the web) Haikelite is not good at measuring Lux.Someone from Haikelite has wrote this.
But how do they measure they prototypes?
And why is there no inspector who takes samples from the actual building process .
Bridging the springs on a MT01 is useless ,no Lumen profit.I think this is why i uses a boostdriver.
On Fet Drivers bridging the springs always gives a Lumen gain.
UPDATE: forgot to mention this is the 70.2 version.
The MT09R ramping control on the lower end is useless, it is basically really hard to ramp to specific lower brightness other than the lowest low it is just too fast.
i made a video comparing the ramping to MF01 and Convoy L6 , see how smooth the NarsilM is and easy to control
Wow, it’s completely unusable at lower levels. I mean, I guess most people bought this light with the intention of using it on turbo anyway, but it’s still unfortunate to see.
yea ramping mode on lower modes isnt the best, compared to my emisar d4 its alot better.
both of MT09R 70.2’s ramp much slower than that
Is the speed of the ramp different in version 35 and 70? Maybe some 70 owner will make a video showing speed.
The 70.2 version ramps fast on the lowest mode but not that fast. Since I don’t use the light for low lumens, it doesn’t bother me. Ramping is not as good as Emisar series and Sofirn SP32A.
Human eye see logarithmically.
It looks like ramping is made linear.
In XHP70.2 is the same speed.
My MT09R 70.2 makes a jump in brightness when ramping up from moonlight and then the rest of the ramp seems a bit more steady. When ramping down the jump is less obvious.
It’s a bit too fast for me. At the moment the model is Q8 where I can easily set any brightness.
Agreed, Narsil is now the standard to judge ramping for me.
forgot to mention, the ramping speed on MT09R that i showed in the video didn’t reach full brightness (eyeballing it probably up to 40% by brightness) i just try to show you the speed on the lower end of the ramp. it took longer to reach 100% at the mid to top end it is much easier to control .
oh and i also forgot that mine is 70.2 version .
the ramping speed is same as Thorfire TK18. I suspect they have same coding which derived from BLF Q8.
Honestly i like narsil ramping so much ….once I use it, I wouldnt want anything elese. Just the right speed 
Pic of the XHP35-driver:
With fully charged VTC6 and all springs bypassed the driver delievers about 6.2A to the LEDs.
