LED lights and drivers

[JoeNorm]

I am trying to wade into the world of LED strip lights and drivers. The Klus extruded aluminum channel is pretty cool.
What is the best way to make the transition from romex to driver to low voltage wire?

This is pretty easy if you have a cabinet to house a big driver, but what if you are trying to get lighting to a thin area such as at the top of a door header recessed in the trim?
Are there good drivers with that will fit in a plastic J-box? Maybe I'd put the driver in the cabinet and run low voltage wire through the wall?

Any leads or idea appreciated. Thanks

not sure on the driver size. But the secondary is typically a class 2 circuit and Art 411 allow a class 2 cable up to 100 watts. Over that its a chapter 3 wiring method
