Fluorescent Light Help
The kitchen has a dropped ceiling with two pairs of standard 4-foot bulbs - I
guess that's what is called T12. This fixture has never been very reliable in the 20 years I've owned the house. Bulbs don't last as long as they should, and on colder winter mornings, while the heater is still warming up the house, they often take several minutes to come on. The last straw came two days ago when a two-week-old pair of Phillips bulbs no longer would light, period. One of those tubes already has blackened ends. The other pair in this fixture is working OK. What is likely to have failed to cause such an early failure on these bulbs? I assume the ballast, but would like an expert to confirm. I'm interested in purchasing electronic replacements, while realizing they are more expensive than traditional magnetic ballasts, but an intimidated by unfamiliar concepts such as "ballast factor". Can anyone provide practical troubleshooting and replacement/selection advice so I can purchase the correct pair of ballasts? Art |
