Fishy_Lips Posted April 25, 2007 Report Share Posted April 25, 2007 Hi there I know what T5 and T8 mean but I had some one talk to me today about T9 tubes I have never heard anything about these before is it a spec for a brand, is it a rating. Be interested too know what they were referring to. Thanks Quote Link to comment Share on other sites More sharing options...
Andrew_W Posted April 25, 2007 Report Share Posted April 25, 2007 The size and shape of a bulb is designated by a letter or letters followed by a number. The letter indicates the diameter of the bulb in eighths of an inch. For example, "T-12" indicates a tubular shaped bulb having a diameter of 12/8 Quote Link to comment Share on other sites More sharing options...
Fishy_Lips Posted April 26, 2007 Author Report Share Posted April 26, 2007 so that stnds to reason that the T 9 is 9/8 thick I have never seen any on the suppliers list I always thought that the T rating was for the width of the pins ie T5 5mm T8 8mm.

alanmin4304 Posted April 28, 2007 Report Share Posted April 28, 2007 I think the T stands for tube. Quote Link to comment Share on other sites More sharing options...

Andrew_W Posted April 30, 2007 Report Share Posted April 30, 2007 to me :evil: so what about T-# bulbs that only have one pin at each end? maybe a T-# is different than a T#... http://www.lightbulbplace.com/bulbID_DD.htm Quote Link to comment Share on other sites More sharing options...
