Look like mtnelectronics only ships to US and intl-outdoor is sold out in 20mm U2 version.
I’ll talk to him, pay for em, and you can just provide an address to Richard.
Is this driver listed as something besides LD-1 on Intl-Outdoors?
I see 18 drivers there and don’t see this one.
Would this work well in a BTU Shocker host?

Off topic:
Would a 60 Watt Weller temp controlled (700 & 800 degree F tips) soldering station work OK for reflowing LED’s?
- It's not for sale anywhere yet. a Handful have been sent out for early ALPHA/BETA testing.
- no, will not work well in a Shocker, at least not how a stock Shocker is configured for 3 LED's in series, 3 cells in series.
- I use hot air or a frying pan to reflow, though I've used on occasion a soldering iron - no the best method. Not familiar with the 60 Watt Weller...
Thank you for the info about the LD-1 driver.
I misread the comments so I re-read them.
Talking about stars with LED’s to be sent to people who already have the driver.
Thanks for the series info on the shocker.
I didn’t see that info anywhere.
Might be good for my HD 2010 or X3.
I did find that you use the IOS driver, but I don’t think (I’m told that quite often) I want to go that far.
I’d change my name to Newbie, but I think someone else already has that.
If the LCK-LED site ever comes back up I’ll find a driver for the BTU shocker unless you know someone who would like to sell the stock or Dry driver.

except mine’s 30 years old and built in a metal box painted USN gray.
Updated to OP in my review thread with this:
Current Controlled medium mode vs. a PWM medium mode
To compare to a Nanjg PWM based driver, I measured the LD-1 in medium mode at 1.13A against a medium mode in a 12x350 7135 PWM driver in the same flashlight (HD2010).
LD-1 turbo mode configured, medium mode 1.13A @tail, lumens: 483 @start, 479 @30secs
Nanjg 4.2A driver (measured 4.34A @tail), medium mode: 1.32A @tail, lumens: 381 @start, 371 @30secs
*** the LD-1 is 29% brighter, even though it is running on 14% less power. I'd say this proves how really poor PWM modes are on a higher powered light, and how efficient true current controlled regulation is.
Thanks Tom, that’s exactly the kind of independent validation I was looking for to show that “should be” measures up to “is”. Thumbs up.
I had the driver in two different HD2010 pills, but using the same HD2010 body. Not an ideal comparison and it's only one value. Hhmm - should go through the lower modes as well...
Thanks for doing that real life comparison!
(Im still waiting for the driver... )
Hello, led4power
Could you change mode option?
Simple mode option is good.
However I want many mode option like Zebralight’s lights.
Simple 3 mode by selecting how long time click it on and each mode I can adjust sub mode.
As you knew, this circuit’s efficiency is very good. I want to use it’s circuit in many power output other that moon, 1, 20, 100% and Turbo.
My wish mode group is below.
1. High group -> 100, 70, 50% and Turbo
2. Middle group -> 30, 20, 10%,
3. Low group -> 5, 3, 1, 0.1
4. Special -> Strobe, SOS, Beacon
Please tell your think.
Thanks
Kim.
s. sorry for my bad English.
I think perhaps the real question is if you can find anyone to write new firmware for this driver.
I’ve thought about writing a ZL-like UI for attiny13a chips with a momentary switch, but I don’t know what MCU the led4power driver is using. It looks like something else that I’m not familiar with. And I’m not sure if the output levels can be changed only via firmware or if it also requires hardware updates.
Why not ramping?
It's much more intuitive(at least to me),and you have practically unlimited numbers of modes(8-10 bit resolution to be precise).
Some people like ramping. I kind of prefer a fixed set of modes with known output and runtime. This way, I know better what to expect (will this mode last for 5 hours or 15?) and can get a better feel for how dark-adjusted my eyes are at the moment.
With my JETbeam RRT01, I can always get exactly the right amount of light… but I never have a clue how long it’ll last. And I always end up setting it as dim as possible for whatever I’m doing, and then thinking my eyes must be really tired or something… until I turn on a fixed-output light and find out I only had the RRT01 at like half a lumen (because suddenly 3 lumens looks bright).
I normally configure my lights for 5 modes — moon (0.1 lm to 0.5 lm), low (3 lm to 7 lm), medium (15 lm to 40 lm), high (100 lm to 200 lm), and higher (300+ lm). Depends on the light though. I really like the ZL UI, which allows for 10 levels with reasonably easy access to all. It’s not so great when lending the light to a muggle, but for my purposes I like it a lot more than ramping.
If I can find time to write a ZL-like firmware for attiny13, I’ll include the source in my firmware repository. I’d kind of like to have that UI on my Skyray King, but I’ve been really busy so I’m not sure when it’ll happen.
I haven’t tried ramping yet but it sure sounds good. Maybe I won’t like it as much after the novelty wears off though. I do like variety so either way I’ll probably end up with several different ui’s rather than just one for every light.
DrJones lumodrv (R86 edition)
Ramping and user programable modes in one UI. Best of both worlds..
No sources for lumodrv though… so no joy.
?
You buy them from DrJones. You can specify number of modes.
I may just be weird. I mostly live in a world ruled by source code, where anything without source has little if any relevance. Seeing people release only the binary, or even making code available only in hardware form, is a bit of a culture shock for me. After leaving proprietary software behind a couple decades ago, it’s a deeply ingrained reflex to grab the code and fix it any time something isn’t quite right. It takes a conscious effort to not ignore anything I can’t get source for.
Ramping is fun but not something I’ll use running on trail. (Planning to put the driver into a headlight). Taking attention away from foot placement could result in a stubbed toe. Like ToyKeeper, I like having solid modes with predictable runtimes. I also have a couple lumodrv s but asked Dr Jones for solid outputs of 5, 25& 80%. ( I love the battery monitor!)
