Fluorescent fixture won't light
This has come up before and I was about ready to replace the ballast. But
others have posted that sometimes corrosion could be preventing good contact between the contacts on the long bulb and the fixture so I worked the bulb in and out of the fixture several times and the fixture is now fixed. No new ballast was needed. |

No new ballast was needed. In this case your fix worked. There is also another thing people should check, make sure the ballast case has a good ground as well. (Sand off a bit of paint/rust if needed) Some cheaper ballasts/fixtures can be quite picky, right from new, and just will not "start" themselves without a solid ground connection. AMUN |

(Sand off a bit of paint/rust if needed) Some cheaper ballasts/fixtures can be quite picky, right from new, and just will not "start" themselves without a solid ground connection. Another issue to consider: Many 1.5 inch diameter 4-foot "F40" "Cool White" fluorescent bulbs are not "true 40 watt" but "energy saver F40" which is actually 34 (sometimes 35) watts. These are generally crankier. True 40-watters are usually "deluxe cool white" (which have less light output) or triphosphor (color-brightening - usually more expensive). I consider it worthwhile to get true 40-watters in a "triphosphor" version such as Philips Ultralume or Sylvania "Designer" or "Interior Design" in order to get good performance, full light output, and color distortions mostly in the direction of making colors more vivid when using 4-foot 1.5 inch diameter bulbs. If the bulb size is not 4 feet by 1.5 inch diameter, the above has much less relevance. - Don Klipstein , http://www.misty.com/~don/ltrouble.html) |
