Couple of shots on the LEDs that might be of use:
First up, the driver end, running a specific LED Driver, at 10Amps, 12 Volts, power comes to the Driver via an IR controlled socket. Plan is I can toggle the layout lighting on and off via the remote, and have the 'on layout' / scenic lighting on another socket.
A view of the strip, which is mounted in a 45 degree 'profile' (basically an aluminium trunk with a diffuser strip running along in front of the LEDs
And the resulting Lighting level at layout level
