To continue the discussion, I rarely combine lighting and receptacles even in residential work. It saves money, time, troubleshooting, and is better for the homeowner, who doesn't lose 100% of power in a room from a single fault.
Thanks guys! There were several time in my old facility when miss secretary plugged in a ceramic heater to warm her toes and left others "in the dark". This case invloves pulling a new surface run off an existing flush receptacle, in order to eliminate an extension cord (no additional load expected). But, as it turns out the receptacle is fed from the light switch in the storage room behind it. I'm not yet sure if any other lights(or receptacles)are on the circuit.
