Hello! Does the switch have to control this lamp? If so, then zero of your two-wire wire (blue wire) should go directly from the junction box to the lamp, and the phase (remaining wire) should go to the circuit breaker. To do this, take another two-wire wire and withdraw it from the junction box to the switch. Through one wire, the incoming phase will go to the switch, through the second it will return to the junction box, and from there to the lamp.
