I got a client who asked me to install LED back up fittings at their complex. I installed the fittings below the electric fence cable which runs in a pvc conduit pipe. When the mains power is on everything works as it should but as soon as there is load shedding and the lights must come on at 30% of its brightness the lights is starting to flicker when the fence is pulsing. Any idea what I can do to prevent it from happening?
