For sale : LD-2 and LD-M2 driver (Updated)

It will work with a forward switch, with the only difference that instead of a half-press to switch modes as you normally would with a reverse switch, you need to click twice to cycle off-on.

Thanks for the info!

Just curious, are there many left?

I have enough parts this time.

I still have 4 of the LD1s, why am I tempted to buy 4 LD2s?

So you can gloat when everyone else’s are gone.

The LD-2 is a nice match to the new flat-top emitters and the Reylight.

A hot flashlight. Celsius, if not sex appeal.

I should have taken a little more care to center the little button but it wanted to stick where it is……….

Thanks, led4power!

I have an application in a headlamp, I am wondering can the modes be spaced closer and not so fire breating on the high end.

I want to put a 6v MT-G2 in the spark SX5 so max brightness will not be the most important thing. (the magnetic lights did not work out so this is a fall back project).

Does the LD-1 or 2 (or other) work with electronic switches?

Also how do we get ramping put in, so we can choose how bright we want it?

and do you have Boost drivers for single cell 6V applications?

Sorry I maybe asking dumb questions.

LD-2 works with e-switches. But modes are fixed AFAIK - it’s not like the ATtiny13a drivers where you can swap/modify programs.

Ramping is one of the ui’s available for e-switch use. A resistor change can reduce the max current. See the into thread for the formula to choose the correct resistor value for a given max current.

I'm not sure if my post/answer about ramping is deleted,so I'll repeat (and definitely must refresh OP):

Ramping UI is removed in LD-2,instead of that,UI_2 in now "discrete ramping",so by holding switch you ramp up/down through existing discrete modes (moon,low,med,high),double press toggles mode between min/max,normal press is on/off (last mode from off),long press from off is for lowest mode from off.

what happened to the info thread? it doesn’t load at the moment:

Yep. noticed that too. The matrix is being wonky this morning!

That’s because the Matrix runs on Windows!

Ledpower is working with SB to fix it

Price and minimum quantity drop!

Minimum order quantity for European Union countries is now 1 piece,and only 2 pieces for rest of the World.

Also more max. current set resistors choices now:5A,7A,8A,9A,10A or 12A

Added: STANNOL 0.7mm HS10 solder wire

2S-4S parts are currently out of stock!

Have you done any further testing with the remote board idea?

It's still in progress.

Thanks for dropping the MOQ :slight_smile:
