that's for your input dude, my neighbour is a HAM radio fanatic, when I say radio shack in the shed, he's got over 40k's worth of equipment. I'm speaking to the guy, I gave him a growlite 315cmh ballast to look at last night, within an hour he had taken it apart, checked the components, rebuilt it with ferrite rings put around the power supply. His words were " really well built, all the rf interference shielding. but I can heat the start up at 8pm takes 5-10mins to quieten down then the him begins' The fuckers told me what time my lights come on, how many im running and the power it's taking.
I'm running LED too, he's even told me the harmonic scale that's affected by the led drivers. I've spoken with MIGRO he assured me they are built to standards... Still having issues with him. I know it's cause his set up is so safisticated, previously I've had 10 lights on running for 8yrs non stop, no issues untill I switched to digi ballast that's the first time he discovered my set up. the fucker was walking around the streets looking for the signals.
