I have several 12V RGB LED strips that I want to mimic a 30W RGB LED. The remote controlled driver outputs 24-32V to the high power LED. Can I just use a transistor/MOSFET? An drawing and product numbers would be cool, or even better a brief explaination of calculations for transistors/mosfets and the associated resistors so I don't have to bother the community with this seemingly simple question.
Would it be possible to use a simple voltage divider to lower the 32V signal to 12V or less to connect to the base of a transistor?
