Fluorescent Tubes
Been 20 years since the tubes in the laundry room were replaced, and
these new tubes flicker for about 30 seconds before becoming bright. Is this just a slow warm-up process due to their supposed energy-saving features, or did I get a pair of lemons? Thanks. |

I've noticed this same problem with new fluorescent tubes, but had chalked it up to the cheap fixtures the guy I was working for used.

The EPA hopes you'll get fed up with waiting and turn the lamp off. ;^) EL |

Can we assume that since the bulbs haven't been replaced in 20 years,
neither have the balast or starter? What led to you replacing the bulbs? Are they the same wattage as the old ones? |

It is probably because the new lamps do not have as much mercury in them as the old ones. Chalk that up to the eiviromental people. They also do not start as well when it is cold. |

Are these tubes 1 inch wide 4-footers or 2-footers and replacing ones hthat were 1.5 inches wide? If so, no wonder they flickered - these take different ballasts. These 2 different sizes are not electrically interchangeable. Are both the new and old tubes 1.5 inch wide 4-footers? If so, are the new ones energy-saving types said to consume 34 watts instead of 40? If so, I am not surprised they flickered for a bit. In my experience, 34 watt 4-footers have a higher rate of being cranky than "true 40 watt" ones, especially in fixtures with "residential grade" ballasts. - Don Klipstein ) |

It's just the opposite, 40 replacing 34. I certainly don't know all the issues, but trying to run 40 watt bulbs on ballasts that were probably just enough to run 34's sounds like a likely cause... |
