I have a bathroom light fixture with 4 light bulbs. Until yesterday, those light bulbs were the classic incandescent light bulbs from GE. That light fixture has been working for the last 7 years with those light bulbs.
I replaced the light bulbs with 4 Greenlite LED light bulbs (3000K, 9W). I turned off the light fixture. Replaced the light bulbs and turned it back on. The 4 LED light bulbs were turned on for half a second and then short circuited (it tripped the breaker). I removed the LED light bulbs and put back the GE incandescent light bulbs. Reset the breaker. Same results: the light bulbs turn on for half a second and then the breaker trips. I cannot use the light fixture anymore. I haven't tried the LED light bulbs in another light fixture.
What did I do wrong? What am I missing? Did the LED light bulbs broke the light fixture?
