looks like simple FET driver without current regulation.
high mode direct drive
Could also be the contact cleaning, the thicker DMM leads and so on.
Any, if the driver can deliver 10A for 3 LEDs, its a good driver. I doubt that wires only could limit the current by over 50%..
Exactly. That explains the 10A++ current. On the down side, regulation is flushed down the drain.
But it's not bad. Simpler circuit, less thing to go bad. Much easier to swap MCU to ATTiny13 (you don't even have to think which one is it), so much space to work with. This driver should be much lighter too. And 10A + U2 emitter, talk about WOW factor.
It this the regulated driver?
High mode current depend on battery. low internal resistance batteries will draw over 10A too.
this is an idear for driver modders... Any way to put current sense resistor and limit max current from PWM ?
yes
seems a good price and beautiful light…… i may pull the trigger on this and get my first multi emitter light 
In original SRK, it pulls initially only around 7.5A at full charge. Much better regulation & current control.
For this driver, I think not too hard to swap MCU and program a 75% duty cycle as High (to get similar output to original SRK).
But easier to just add current sense resistor... it has to handle 10A so high wattage is required. But space isn't a problem in the new driver 
I'm thinking just Fujik a 10W resistor to a copper pad (lots of them I see) and rewire FET output through it - should work.
Been pondering this all day….result…. couldn’t resist… ORDERED 
Really? We want LESS amps now? Is this still BLF? :P
i wanted the regulated board for longevity reasons.
did you see the thin aluminum disc that the LED’s are mounted to that only contacts the outside of the light via a few threads and a small ledge? thats why i started a thread about getting a custom slug of brass to mount the LED’s to rather than the thin AL thats in there now.
yeah the simple driver is a beast with good wiring, good batteries and cleaned up connections. i definitely will keep it around. but for a light i want to really last and use for significant periods of time on high… yeah not so much.
the low mode has PWM, if you applied 75% duty cycle to a high mode (and left direct drive as “turbo”) youd have PWM in your new “high” mode unless all the components are compatible with a high PWM frequency program on a ATTiny mcu.

Allrite, I ordered the black Cw after Manafont screwed me over with the mimic instead when I ordered the original King.
I was up early drinking some coffee and a little birdy told me
” swap your SRK driver with the Apex driver “…So i did.
Thats one smart bird!!
Anyone recieved theirs from the new batch yet???
may I know where did you get the apex driver?
ordered mine saturday cant wait for it to ship
Where did you buy it and what does it do?
man oh man soooo tempting
OK, on the custom logo do you just put the logo in the comments section when paying with paypal? Is the custom logo lettering or symbols? If letters, how many spaces can be used? Where is the custom logo placed on the flashlight?
mine arrived in the uk yesterday, just have to wait for royal mail to get it to me now
