Sorry if the answer is obvious. There's four lightbulbs in the room, two LED and two regular, and they all behave differently when I turn on the lightswitch. When I flip the switch, the two LED lights turn on automatically, one of them normal and bright and the other one super dim. After a second delay, the two other lightbulbs turn on but flicker the entire time that they're on. I already checked that everything is screwed on tightly, and the person who had the space before me made the comment that the flickering had been going on for awhile. Does this just sound like three bulbs going bad simultaneously or should I get someone to look at the wiring? Thank you!
