This is the lemon made, or I mean, PZGRL (Poltava, Ukraine) made CW F80T12 EOL fluorescent tube. Really nice to see thic double-coiled filaments in PZGRL tube, because usually PZGRL tubes have very shi*ty thin short garbage filaments. Quality tube, with quality CRI, very nice CW light is produced, you can compared it with modern Tungsram CW or Philips CW. This tube came from my neighbor who is changing his fixtures in his garage. It is EOL, sadly, but still runs on my IS ballast with two F32 outputs hooked together on it. Look at those cathode shots! :)

Nice little peek of the cathode (:

Thanks. I really love getting these tricky shots of the cathode whenever it is possible to do. The clear glass window near the endcap can be half a millimeter wide, and it would be enough for me to go and spend 10 minutes trying to focus the god damn camera in that cathode

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 ;

Keep in mind that you can light up EOL tubes perfectly on a rectifier. Just hook a Graetz circuit in between the magnetic choke ballast and the lamp. Just have a look that the diodes man handle at least 2kV for the ignition voltage peaks, or you solder 2 or 3 diodes in series on each side. That's how I have created an 18W and 36W rectifier fluorescent batten. Like this it's possible to light EOL tubes up until the other electrode runs out of emitter. You just have to insert the tube the right way into the fixture.
