Did Dr. jones make a HF17 driver with AMC7136 so that it used less chips than the AMC7135 version?

The drivers I am looking for would be the Dr. Jones solid copper driver options that will fit a convoy C2+ host, Solar force L2P, or D2.

Here’s the announcement. I don’t see a for sale thread. There is mention of Wight’s QX7136 driver.

There's always L4P driver...

I see. Not really an available option then.

I am not familiar.


Does everything you described

Out of curiosity I tried to visit drjones website http://drjones.nerdcamp.net/ but get a ‘connection has timed out’ message.

There are many other chips that are interesting. I and Mike C (among others?) have used these: AMC7138, CN5710, and CN5711. I’m sure there are some others that have promise as well (and I’d love to learn about them!)

I see.

The idea was that I need good amount of continuous runtime at 300 - 350 lumens without overheating at that output.
So the 3x AMC7135 and firmware with a setting option for that is all I need. So I don’t see the need for 6 or 8 chips on 2 sides of a driver.

But I did want the best quality driver build I could get, which seems to be the ones with a bunch of 7135 chips.

Nothing wrong with the build quality of Nanjg drivers though.

My understanding is that the Nanjg drivers are not built to the quality of the dr jones drivers. Plus the Nanjg drivers don’t have the settings options that the lucid firmware offer.

With the Nanjg driver, I would have to pick the correct number of chips to get the desired power level at one of the settings. Then I would have to select through the settings every time I turn on the light to get the output level.

Where with the Dr Jones driver and lucid firmware I can just select what ever output and switch option that I want, and lock it in.

Hmm… Nanjg drivers are built fine.
It’s a PCB with parts soldered on them, like any driver.
I don’t now what settings you want, other than what i recall from a previous topic, which is 2 or 3 modes and maximum 300 or 400 Lumen or so.
Since you’re looking for separate drivers, i assume you can solder, so with a 3x 7135 Nanjg AK47 you can choose 1 of the 4 stars to solder bridge to minus and choose whether it’ll be 2 or 3 modes.

The only down side to the good ol’ AK47 4 group drivers is the PWM can be audible sometimes, it’s around 3 kHz.
For the rest, they’re fine and do all you need, and are very cheap.
An no time consuming fuss with configuration menus.

My soldering skills have room for improvement. So is my knowledge about this stuff. Would rather just buy something set up how I want.

300-350 lumens is the target no higher, with no overheating at that setting.

Don’t really like configuration menus but once it is set and locked in all is good.

With the 3× 7135 Nanjg AK47, I wouldn’t be able to lock in a single 300 or 350 lumen single setting.
With the lucid drive, I can set any configuration I want and any power level I want.

What about thermal protection? What has it and what doesn’t?
What is easier to set up a lighted tailcap click switch with?

Maybe me, but i wouldn’t get a complicated driver if i just wanted 1 mode.

You could get these too:

But i think 2x 7135 will get you those 300 Lumen already, since LEDs have considerably higher efficiency at low currents.

Overheating in an aluminium 18650 light at such low powers is not an issue.

It seems you want (to assemble) some simple 100% foolproof lights though.

Are you planning to use protected 18650’s in them?
(because those boards i linked have no over discharge protection)

Otherwise, go for some configurable boards, but bear in mind that people may accidentally enter config mode somehow.
(it happens)


And yes. protected.
Would like thermal protection, and over discharge protection.
Looks like the 17mm DrJones H17Fx Driver w/ lucidrv2 has full thermal control, and battery monitoring auto step down.

If config can be locked in it would work good.

I’ve also used CAT4101 and CAT4104. However, they have thermal shutdown which can be annoying. The 4104 TDFN package is conveniently small but rather sensitive to heat. I really like the CN571x thermal throttling, it’s not noticeable compared to the disco mode that the 4104s can produce.
