adding some overhead lighting in the basement

I am planning to add some additional overhead incandescent lighting to two rooms in the basement. I have a sufficient quantity of 14-2 NM wire to complete the job. Both rooms are on the same circuit, protected with a 20 amp breaker. Is it safe for me to use this 14-2 wire for the additional wiring or should I get some 12-2 ?

You must use 12/2 on a 20 amp circuit. 14/2 is only good for 15 amp circuits.

Is there enough of the 14-2 wire and do you have an empty slot in your panel? You might want to consider the alternative of running a new 15 amp circuit particularly if you are quite decided on incandescent lighting.
The good conscientious technician or serviceperson will carry extra oils and lubricants in case the new pump did not come with oil or the oil was accidentally spilled, so the service call can be completed without an extra visit.

Change out the 20 amp breaker with a 15 amp and install your fixtures. Otherwise you will have to pull a new 12/2 circuit. The choice is yours.

if your existing wires are 12-2, then you should use 12-2. If you use 14-2 then as above statement, change the breaker to a 15 amp. I would use 12-2 and keep the 20 amp because someone down the road may replace the 15 with a 20 not knowing there is 15 amp rated wire on the circuit.
