    Can anyone explain how to calculate amps used on low voltage lighting.

    For example. would 10 * 50 watt 12volt bulbs use the same amps as 5 * 100 watt 240 volt bulbs.

     

    Thanks

    Here is an online amperage chart that might help Dave.

    formula is as follows

     

    Current = Power/Volts

     

    So:

    10x( 50/12 ) = ~42A

    5 x (100/240) = ~2A

     

    So the obvious answer is no! but they will both cost almost the same to run, you will have some extra overhead for the ELV transformers.

    If you have more questions feel free to contact 1-813-978-3700 for more install information. What set of outdoor lights do you have though? Always try and use a lower amp light than you think.

    Ray said:In both the voltage levels ie 12 V and 230 V. power consumption is same ie 500 watts. The Amps = W/V and styhus shall be 500/12 amps and 500/230 amps
