Heres a few circuits for driving diodes

From Guido:
Be careful as most of these diodes are M cased common anode.
It just might be just easier to modify a Leadlight 105 board

Marconi;
Thanks for the input! Sam suggested the Roithner EU 38 board to me.
I believe it would be cheaper to buy a finished board vs building my own, but I can't seem to find anyone that sells them in less than 1000 lot quantities. Same thing for the leadlight boards.
Do you have a source for populated diode driver boards that can be bought in small numbers?

Hey, For those of you who have tried to build your own...
The second driver circiut is not correct..
It is show having the LD connected from the top of the FET and ground ..
Not correct.
It should be connected to the + rail and the top of the FET.

Along with a protection diode, resistor and cap.

I believe roithner can sell in less than 100 units, at least as far as their price list goes. I haven't asked them about that though, so can't really say.Do you have a source for populated diode driver boards that can be bought in small numbers?
Remember the future?, That'd today, as you imagined it yesterday.

Yes, But ours costs a bit more than others you can find .,Do you have a source for populated diode driver boards that can be bought in small numbers?
Also probably a bit ugly as they were made to fit inside our modules..
Besides, we didnt find any that will work for our application..
So we made our own, and glad we did!!!
