No! Most lamp cords are made with 18 guage wire, some speaker wire is made with 18 guage wire too but the insualtion of the wire is very different. Both wires have insulation for their intended uses. Supplying a lamp with line voltage and supplying a speaker with low voltage are very different. The speaker wire is not meant to carry line voltage and may overheat and or melt.
using 18 AWG speaker wire to rewire a lamp
10 AWG wire will have less resistance per foot and therefore you can have longer runs with 10 AWG than 12 AWG without as much loss of signal. Additional to loss of signal there is a need to maintain a low impedance driving the typical speaker with its 4 ohm or 8 ohm coil resistance, to avoid frequency-distortion. A guide rule is that the speaker cable should have a total resistance around 1% of the speaker resistance (or less). On that basis, for 5 yards of speaker cable for a 4 ohm speaker the wire size would be 4 sq. mm (11 AWG) or for an 8 ohm speaker 2 sq. mm (14 AWG). <<>> Using the above formula of 1% of the speaker resistance the above answer is not correct. For a 4 ohm speaker at 1% is .04 ohms. The resistance of #12 wire is .001588 ohms per foot. This will allow you to run 25 feet and still stay within the parameters. For a 4 ohm speaker at 1% is .04 ohms. The resistance of #10 wire is .00100 ohms per foot. This will allow you to run 40 feet and still stay within the parameters. You can see, what the first answer states is correct.
12 awg is larger.
AWG stands for American Wire Gauge. It is a standardized wire gauging system for the diameters of round, solid, electrically conducting wire.
The larger the AWG number the smaller the wire. 10 AWG wire can carry more current than 12 AWG wire.The wire sizes of 24 and 26 are the smallest that are used in the electrical.See related links below
6 AWG wire
If you use a heavy AWG speaker wire, you can easily go over 60 feet or so, depending on the speaker.

American Wire Guage. The smaller the number the larger the wire. As in an AWG 14/2 wire is much smaller than an AWG 10/2 wire.

For typical residential house wiring 12 AWG wire is required for a 20 Amp breaker. If you change out the breaker for a 25 A breaker you would have to rewire the circuit with 10 AWG. In that case you could up the breaker to 30 Amps. All outlets and switches should be rated at the same voltage and current as the breaker.
Red is usually positive and Black negative. Make sure you do not get this backwards. I recommend 0/1 or 0/2 AWG (Guage) Wire
American Wire Gauge ( AWG )
Use a wire table to find the cross-section area of #33 wire, multiply by 7, then find the AWG for that cross-section.
