Is it just me or are "standard" fluorescent lamps getting shorter? « on: January 10, 2017, 08:53:54 AM » Author: LampLover
Has any one else noticed modern fluorescent lamps are shorter then the supposed standard length as in the lamps will fit into the fixture and still light up but the pins are exposed on one or both ends

Example
I now have a Luxo inspection lamp that takes four F4T5 lamps (Two being Daylight and the other two being BLB). The lamps are supposed to be 6" (I have not measured them though) and I believe they are a little shorter then the "standard" length because the pins are exposed on both ends of the lamps. The lamps still make contact with the socket though


PS: I will post pictures of the Luxo inspection lamp latter
It has Sylvania/GTE lamps

I've noticed this too. Like in my early desk lamps, the Mazda lamp fits in the sockets perfectly, while some newer Sylvania lamps leave about a few mm gap on each side. The GE t12 version (aforementioned lamps were f15t8 in this case) was maybe a bit too tight. Maybe tolerances vary somewhat between lamp manufacturers as well as light fixture manufacturers. I've also noticed that Westy f40 lamps are just a tad longer than new sylvanias.

Not just you, this happens with the European lamps as well
