Powergroove F15T8

Powergroove F15T8

After I did the F8T5 one and the F6T5 power twist, I just had to start working on bigger tubes. This was a first attempt on an F15T8. I think this one is a TFC or something similar. I'm testing it in my preheat American Fluorescent F15 closet strip, which I have modified further with different lampholders and starter sockets.

I wonder if they formed the twists and grooves in the glass tubes before of after sealing the tubes with vacuum? I would think that they would heat the tube on a spiral torch for powertwists and repeating torch flames for a powergroove and just pull a vacuum and the twists or groove would form right in front of your eyes, and then they just keep the tube in a kiln for a day or two to anneal the stresses in glass? I would pee my pants from joy if I could see the production process right in front of me

New lighting technologies is a pity fest everywhere you look. From LEDs that last only for two months, to a never-ending global starvation of t8 fluorescent tubes.
We shall reinforce ourselves with good old full mercury t12s and HIDs made to surpass one's life, and give them all the middle finger ;
