    You can see, by the Ohm's Law chart I provided, that the voltage is needed to complete the calculations.

    And, if the system voltage is 3 phase, the voltage needs to be multiplied by 1.73, before using Ohm's Law.

    Also, since you want to know KVA, need to know the Power factor of the lighting.

    So, provide:
    System Voltage
    Phases
    Power Factor
