If you look at the right side of the drawing you will see a difference in the diodes.
The advantage in each metod is that it works with the respective diodes.
(Case isolated from battery is simply difficult to achive in most hosts.)

Thanks Toke so for a LPC-815 I have the option of the 1st or the last one.
Is that why they solder 2 of the pins together on the diode case pin and neutral.

Red diodes are case negative by default. So option one for you.

With 445nm and 405nm diodes, they are case neutral. So if one was to use a flexdrive with either one of these diodes, that when you solder the negative LD pin to the case pin. That will make it case negative and you only have to wire the positive input of the flexdrive to the positive of the battery.

PM Bogartman or check e-Bay. I think he still has some microFlexes in stock. Price is a little higher, but well worth it. 1) you can get the driver, 2) you'll get it quick, super fast shipping, &3) he packages it like it's in an armored car, so you get it safe and sound.
