What's the problem? A: It's most likely not a problem with the fluorescent bulb itself, but rather the ballast that supplies the electricity. In this case, simply replacing the ballast with a new one will resolve the issue. [00:17] Q: How do I choose the right ballast for my home? A: Check the shape of the fluorescent bulb (e.g., straight FPL), the wattage printed on the ballast (e.g., 36W), and the number of bulbs connected to the ballast (single-lamp or dual-lamp). Make sure to purchase a ballast that matches the specifications. [01:12] Q: How do I remove the wire from the socket? Can I just pull it? A: Simply pulling it won't remove it. Use an awl or other sharp tool to poke the small groove next to or above the wire hole and then pull the wire out. [04:01] Q: Is there anything I should be careful of when re-inserting the wire into the socket? A: When plugging wires into the four socket holes, make sure to group wires of the same color together. For example, they should be arranged in gray-gray, white-white order, and never mixed colors. [05:25] #FluorescentBallastReplacement #BallastFailure #FluorescentLampFailure
