[Shop-talk] Plug for 14/2 solid wire?

The code is not clear, i.e. it states a few things that can be interpreted as "no Romex in conduit" but doesn't explicitly forbid it. I also think it explicitly permits it when going from a protected area (my garage walls) to an unprotected area (the new junction box flush mounted to the ceiling). 

Realistically, I'd worry more about heat buildup in an insulated wall that I would metal conduit in a garage in New England. I suppose some future yahoo could repurpose ths wiring to run something beyond spec, but as it'll be hardwired to the 11 watt lights I'm not concerned enough to buy individual wires to run through the conduit I am not sure I'll be buying yet :-)

There's an ugly floodlight already switched that I'd like to remove, and if I can repurpose the wiring to that into a junction box with the new light wiring, and replace the switch with a timered switch, that would be quite close to "right".

All of this should be done within the walls, ceiling, etc of the building, or in conduit if mounted on the surface.  The switch you use can incorporate a timer if desired.  There should be no plugs involved, and no lamp cord.  Of course you can rig up anything you want and make the lights come on, but it won't be proper or safe like that.  Is this intended to be a permanent installation?  If it is, do it right.
