Hoping to get some help from the experts. I have a two bay, two story garage attached to the house. Previous owner has 2-bulb fluorescents plugged into the socket adapters screwed into single bulb fixtures in the ceiling. How unsafe is that? I ask because working out there this weekend, I heard a sound that sounded like my sprinklers going on and looked up to see the fluorescent fixture smoking. I am assuming this was the lighting set up for the 12 years the previous owner held the house (built in 1998). Was this most likely a cheap fixture punching its last ticket after 13 years? After everything cooled off that light turned on when I flipped the switch for a quick second. I assume I should be replacing the single socket with a direct line to whatever light source I choose? Or is it safe to plug into the socket with an adapter if I buy a new fluorescent fixture? Thanks.
