Just wanted to share some parts that might give you ideas for controlling your fixtures remotely.
This development board allows for a variable PWM input voltage and converts to 0-5V or 0-10V analog.

It's less than $5 on e-bay.
To understand how this board does what it does, you can check this article out.
I'll talk more about how to actually integrate this into a production fixture next time.
Thanks.
