So in direct drive mode it is not limited to 12A, correct? It would behave just like an ordinary DD?
There will be 4 versions of LD-3 available. 3A,6A,9A and 12Amps. DD feature on high is firmware regulation override,and there are some theoretical limits for DD current because of that,as shown in graph:
Looks very good.
Is there a typo in the data sheet? The Current set sub-menu text states that the 12A version can be reduced to 9A, but the chart indicates that it can be reduced to 8A?
I will definitely need some of these, probably 10-12 of them. Sometimes the side e-switch is a nice plus, in a smaller light, but I don’t have a problem waiting for that one to come out.
Please let us know the price and availability of these as I sure don’t want to miss out. 
Great work, LD-2 is my go to driver for all of my lights that I’m going to use myself. Looking forward to resistor free LD3 !
I was just thinking about building some lights again. I’ve got money ready! Thanks for all your work.
Max. Current setting in UI is different thing,for 12A driver you could set it anywhere between 8 - 12A;all modes will be scaled down by same percentage. Graph shows max. theoretical DD currents on high mode (if you choose DD in settings). For example,if you want to build triple xp-l,you should choose 12A version;with good battery max. Current on high could be 13-14A with DD activated. It’s important that this “predicted” current is lower than max. DD current from graph. It would be bad to choose 6A for driving triple xp-l,since its max. DD current is lower than those 13-14Amps;driver would limit current to value from graph (9.2A at 4.2V and lower than that at lower voltages).
^ PM sent.
So since I won, could I use this to drive at 11amps from 4S cells? It’s only clicky switch right now though, not e-switch?
4x XHP35?
This would generate too much heat for little 17mm driver with typ. batteries and leds (output power is ~175W). With enabled DD on high - maybe, but for these big bad setups you should wait for LD-M3 to do that job.
Yes, for now only clicky switch is supported.
Yes, 4 XHP35 is what I was thinking.
TELL
ME
MORE!!
:D
Since the lower modes are % and not fixed values, If I want to use it with a triple XPL HI setup but want lower mid modes, because if I chose the 6th group mode 30% of 12A is 3.6A which is way too high for medium in a small light, can I go with the 6A version instead?
This way I can set it to DD on 100% mode and get 6A+ while the 30% would remain at 1.8A which is perfect for medium. Would there be any negative by using the 6A version to power a triple XPL setup other than lower current and efficiency at turbo?
Also, is the temperature step down flash still present on the LD3?
Thanks
Is there current limits for multi-cell multi-leds versions?
6A version has 9,2A max. DD current,this is maybe Ok if you power that triple xp-l with 18350 or non-high drain 18650,but if your plan is to use high drain battery,you can use 9A version,decrease max. Current to 7A to get lower medium-low mods,and enable DD on high for max current oh high.
Driver works equally in all setups.
4Sx12A=180W powered by 17mm driver? It should take extra 24W somewhere away from components, how this could be real? I suppose chips have internal thermal protection.
I don’t need it necessarily but I still like it 
LD-3 can handle about 5Watts of power dissipation in typ. light with help of silicone cubes,fujik and similar.
For your setup check post #30
I really like your drivers
They work really great in some of my flashlights.
What I do not understand is the UI.
In my opinion( and I am not alone) and use,
the LD2 has the best UI,specially the ramping is really cool.
Why change the “best” ?
