Nice. I'll be following. Hope to work this into a planned full-spectrum build for my 200 gallon! I won't need the controller, but the LM3409 would be great for either XM-L or 100W chinese chip array build.

The next driver is Based on the National Semi-Conductor LN3409. I designed these drivers to utilize components that will allow them to run led loads up to 60 volts/ 3,000 ma. This design will allow the newer Cree XM-L leds to be run at their Max. Each driver's maximum current output can be custom tailored using the on board trim pot. Since each PCB can only hold 2 LM3409's. The driver PCB will be split to create 2 driver sub boards that will mount under the controller. I include selectable jumpers in the design to allow each driver to be addressable by the controller.

That's it for now- the PCB's needed for this project arrive tomorrow. I'll post some pictures of the finished product after it's put together.
