    By the way I'm in australia and the power outlets here are 240v and the circuits are normally on a 10 amp circuit breaker

    Depends on the wattage of each lamp.

    Typically you can go to 80% of the circuit for extended use (3 hours or more in the US).

    Watts divided by volts equals amps.
    In your case it would be 8 amps.
    So a 10A circuit would be 8 amps, times 240v, equals 1920 watts continuously.
