Expanding on that.....
Connect COM to the Live wire of the mains supply, connect L1 to the Live terminal of the light fitting, connect the Neutral terminal of the light fitting to the Neutral wire of the mains supply. But before making any connections, make sure that the mains supply has been switched off at the distribution unit. Mains voltage is lethal. Familiarise yourself with, and take, all the necessary safety precautions.
That will certainly turn the light off, and probably everything else in the house, leaving the OP with the task of resetting circuit breakers, replacing fuses, and/or (at worst) replacing burned out wiring or summoning the Fire Service.
@bassett1991 Don't follow audioguru's suggestion. He wasn't being serious (I hope!).
Use an OHM meter to test the switch to see what you have. Use a VOLT meter to test the house wires to see what you have. The black house wire should be the hot 120 VAC wire. The naked copper wire is ground. The white wire may be ground too depending on the circuit box set up but in any case white and black supply power to the light.

In the USA house lights are 120 volts and industrial lights are 240 and 480 volts. Black and White power things in the house and the black is the hot wire. In industrial control circuits the white wire is the hot wire red is the typically used for the control circuit wires all wires are numbered. Industrial 3 phase are black wires. If you work in a mine they use high voltage stuff electric motors are typically 5000 volts or more.
