I’m really happy you adapted the mode spacing to make it more linear.
Looking forward to tinker with these

Do you have a link to the operating system, or is it hopefully just a couple of modes? You might have posted this before but I might have lost the link.

Tried to order 3 drivers. Got all the way to the end, pressed the Send button and got “Sorry, there’s a problem. Please try again later.”
Edit- second try- as soon as I his Send, I went right back to the Paypal login screen.
Third try- waited an hour and tried again. This time it worked.

For 4 LD-1 drivers. It'd be great if they were intact on the board like in your picture.
Thanks Very Very Much for your effort on this driver, the time and hard work are truly appreciated and I can't wait to get one of these beauties in a light!
Ill take 4 to Australia (as above, be nice if it was ready to use, but still in that nice little formation like the OP image). Will edit in PP info in a few minutes.

PayPal sent for 4. Good job on this.
Three Tanna leaves to give him life, nine to give him movement. But what if he eats the whole bag?

My 2 drivers were in the mail box an hour ago.Proper anti static bag and all.Impressed.

3 drivers arrived. Well packaged, looking good. This will be a good weekend.
Thx a lot.
UPDATE:
Couldn’t resist, had to test one, clicky switch only for now. Only on a test rig and only with a Sanyo 2600, as 5A might fry my testing LED (I just developed a dire need for an LED on copper with ample cooling for testing).
Result: 4 modes; 11mA / 100mA / 1047mA / all-the-Sanyo-can-deliver-mA; off-time memory. Very good so far. And there is much more to explore.

Not sure why shipping to me always takes longer than the estimated time. No problem though. There is no rush..
Recieved my drivers today!

Probably because Norway is outside of EU(union).

Imagine my surprise and great pleasure when I saw the little package in the mailbox from Croatia! :bigsmile:
These are Beautiful!
And the anti-static bag they’re in is so professional, thank you very very much for leaving my 4 intact in the one piece board, just love it!
I’ll have to separate them, of course, but will do so one at a time as they are used.
Now to take pictures to commemorate this huge effort!
THANK YOU!
I cant wait to get back home, I might have presents waiting!!
A quick For the Record telling of my first use…
I took these numbers with a Mastech clamp meter at the emitter, via a short loop of 20ga wire between the negative driver lead and the star…light fully assembled with an XM-L2 U2 1A on a copper direct thermal path star and running without the bezel and reflector, spring bypasses top and bottom…
0.02A at 3.933 lumens
0.12A at 42.1935 lumens
0.99A at 409.86 lumens
4.82A at 1604.25 lumens
the meter varied on the .02A reading, going between .01 and .02. As well as between .11 and .12 on the low mode. This was using a Panasonic NCR18650PF cell at 4.20V, I tried the top end with a freshly charged Efest 35A and got the same number.
For me, this translates into SWEET! :bigsmile:
If you’re on the fence over whether or not to get this driver, just go for it!
I put one in a Fenix TK22 that was originally set up with a tail clicky for on/off and a side switch for modes. It was also rather anemic, with some 600 lumens. The LD-1 went in hard, as the original driver was a 2 board set-up, but now that it’s in I’m loving it! The tail clicky works all the modes in normal form, for use as a tactical light. The side clicky works the light as an e-switch normally would, provided power is on at the tail switch. So it’s the best of both worlds, with a lock-out for the side switch. And I gained a doubling of output to over 1200 lumens!
I Highly recommend this driver.
(also put one in a Sinner Ti light, this one was super easy to install and works like a champ on the tail switch.)
Dale, yer killin’ me! I want this driver, but don’t currently have the funds! :_(
