A flickering or dead fluorescent bulb can be a nuisance and it may be time to replace it. Before going out to purchase a new bulb, ensure the bulb is the main problem. By checking for surface-level issues, cleaning the parts, and looking at the electronics, you can determine whether you have an easy fix or a trip to the hardware store.
- 1 Look for dark areas at the base of the bulb. When bulbs age and have been used for a long time, brown spots will appear. If darkness begins to form at the ends of the tube, the bulb may be near its end. While they may still light, they are wearing out and will die soon.
- If the darkness only forms on one end of a tube light, flip the tube so the darkened end is on the opposite side of the fixture.
- If darkness forms on one side of the tube, rotate the tube by 180 degrees from how it used to sit.[1]
- 2 Inspect the pins at the end of the bulbs. The pins of the electrode connect the light bulb to the power source. If the pins are bent or misaligned, use needle-nose pliers to straighten them before returning them to the fixture.[2]
- 3 Test the bulb in a working fixture. Remove the bulb from the fixture in question and test it in another lamp. If the problem lies within the lamp, the bulb should work in a separate fixture.
- If testing tube lights, be sure to test both bulbs even if only one is out. Currents travel between both tubes and either could be causing the problem.[3]
- 1 Check your electrical panel box. Ensure the circuit is not broken. If the breaker has been tripped,…
