can someone please tell me if a 500Va dimmer switch will power 500w of lights, from my knowledge a 500Va switch would be more than sufficient as most lights run from a 5V circuit but just wanting to check, Cheers!
if you have 2 fittings running from 1 switch then you have probably overloaded the switch as most switches will only power one fitting you will more than likely need to replace the switch with a more powerful one or change your bulbs to ones that when all added up only come to the total wattage...
