[VAL] RE: 12 v Thin-Lite fixtures

["Forrest McClure" <rollie51@xxxxxxxxxxx>]

Perhaps Dr. Gerald can answer this one. I recently changed out the cool 
white fluorescent tubes in my 12 v Thin-Lite fixtures with Sylvania 
"Kitchen & Bath" tubes. The warmer color is a big improvement over the 
cool whites. However, I am now experiencing problems with getting the 
Thin-Lites to turn on. They act as though the tubes are not seated 
properly or as if the ballast is going bad - to get them going I have to 
tap them. So, whenever the tubes are changed is it also a good idea to 
change the ballast also? Or are the pins on the ends of the tubes just a 
slightly different size and are not making a good connection? The 
Thin-Lites are only about three years old, and when the cool white tubes 
were in the light fixtures they worked perfectly.
