A friend of my brother's is getting a new house built from the ground up. This is in the United States, 230 volts split into two, 115 volt sides of the line. A licensed electrician hooked up everything. There were about 100 LED recessed lighting canisters throughout the house - not just in one concentrated area. Power was turned on for the first time, and every single one of the LED lights blew out. What do you think happened, and whose fault was it?
