[QUOTE="ProDave, post: 539977, member: 6969"] I asked earlier about heating. Our house is heated with an air source heat pump and sometimes at start up the downlights flicker for a few seconds when the compressor starts up (in spite of it being an inverter driven soft start compressor) I suspect something else close to you has such a large load with a high start up surge causing a fluctuation in supply voltage. There is a reason the DNO now ask if there are any heat pumps or similar high startup current loads when requesting a new supply. Some LED lights are more susceptible to flicker due to fluctuating voltage than others. [/QUOTE]
