Sanjay ? Why would that call me Sanjay ? I don't get it.
I do have one distinct advantage- family, from decades of pa yapping about stuff at the dinner table.
One old chap "national sales manager" for a brand i recognised went on about their LED made in America and American stuff was quality and lasted for long. I told him he got it all wrong. I was in America for the last 6 months and America was Fordian and way behind in LED. Their lights are ancient (pa had complained about that). The best makers of LED are from Korea who also happen to make American military stuff. He eyed me quietly. I also told him LED doesn't last like LED tvs and need to be replaced every so often and the product itself isn't quality. LED is for colourful energy saving efficiency and is tethered to fashion. Commercial shops change their lights every couple years to attract customers. LED makes a cheap alternative because it is a cheap alternative for the fashionable gimmicks they offer. Industries change their LED and lighting every so years for safety. No need to last. He nudged his business card in my hand.
I may not be trained in his stuff but boy oh me I had a dad obsessed with his work, and loved to glory on and on about lights, switches etc. etc. no amount of training can substitute for family.
