Wait! djozz, did you say clicky only? I know a lot of lights are clicky, but sometimes a clicky just won’t do. Wonder why e-switch was left out! :cry:
Otherwise, just from reading the page that PD zoomed in, it looks to be a very worthy upgrade for LD-2! I just hope LD-2 stays available for e-switch lights, or another alternative is offered.
EDIT: I just glanced over the preliminary datasheet, and I’m amazed at the depth of configurability and functionality of this driver! Still wish it would support e-switch, but for a clicky switch driver, I don’t think there’s one out there that compares!

Note <10mohm for DD drivers,that means just that,less than 10mohm.Since there are a lot of different DD drivers and even more different FETs used,internal resistance varies from maybe 2mohm to 10mohm,but most of them have 4-6mohm.
Well, i was always wanted an Eu source for a good drivers like yours that are suitable to drive a single XML emitter type with 2( or more) 18650s, especialy in the 17/20mm form factor cause atm we have only MNT ones
Also a good driver for XHP35 in the same form factor driven by 4 Liions
Thanks! After I saw the datasheet, I figured that was the case. This really does look to be an awesome driver! Good job! I wouldn’t have thought there would be much room for improvement after LD-2. Hardware-wise, it seems I was right, but the UI of the LD-3 is incredible!
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:
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.
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).
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.
