Fluorescent lights upat ends only
I have under-cabinet lighting, traditional fluorescent tubes. One of
them lights up at the ends only. I've tried removing and reinserting it, with no improvement. There's no audible buzz or hum. The fixture takes only the one tube. Is it likely to be the ballast, or something else? And is the ballast that little silery-metal cylindrical thing, about an inch in length and maybe 3/4 of an inch in diameter? -- Stan Brown, Oak Road Systems, Tompkins County, New York, USA http://OakRoadSystems.com Shikata ga nai... |

That's the starter; some older fixture had separate starters, virtually all larger ones have the starter built into the ballast. Try moving one from the another fixture, if it turns out to not be the lamp. Gary -- Gary Heston http://www.thebreastcancersite.com/ "It's kind of hard to rally 'round a math class."

Yes, I did try another tube; I should have mentioned. Result was the same. Is it likely to be the ballast, or something else? And is the ballast that little silery-metal cylindrical thing, about an inch in length and maybe 3/4 of an inch in diameter? That's the starter; some older fixture had separate starters, virtually all larger ones have the starter built into the ballast. Thanks. I had never heard of a starter before!

There's no audible buzz or hum. The fixture takes only the one tube. Tried a lamp from one of the other fixtures? That's a quick way to determine which is at fault. I also saw on a Web site that a lamp that is dark at both ends (when not under power) is likely bad or near the end of its life. This tube was white for its entire length. That's the starter; some older fixture had separate starters, virtually all larger ones have the starter built into the ballast. Thanks! Oddly enough the other fixture has a place for punching out a hole for the starter, but no actual starter. So it must have a newer-style ballast. (These fixtures were in the house when I bought it four years ago, and until recently I just ignored them.) I would not have known the name "starter" without you. I took the one that I had to lowe's and found that they were sold in blister packs, two starters for $1.98. that seemed little enough to risk, so I bought a pack. Sure enough, the starter had been bad, and I now have under-cabinet lighting. Of course, all is not well. The ballasts are he old magnetic ones, and one of them buzzes quite loudly. So I just don't use that fixture, because I don't want to replace the ballast. (There's a master switch for the three of them, but they have individual switches as well.) -- Stan Brown, Oak Road Systems, Tompkins County, New York, USA http://OakRoadSystems.com Shikata ga nai... |
