Okay so here's the deal I'm sent out to a house to finish a remodel and install a set of ceiling lights. So I go ahead and hook up the lights and after a couple days I threw a couple bulbs in them. After a day or two when I come in the morning I flip the switch and pop there goes another bulb. So I changed it out for another bulb and a few days later pop. Voltage is not that high only at 112-118 volts.
