In the haul there was 5 of these tubes, all NOS. These are genuine SLZ branded fluorescent tubes, straight from the factory. Nice tubes, pretty bright for a soviet tube.

Yup. These tubes were bought for the school's fixtures when the school was built in 1987. Btw, had some casualties not too long ago, made a whole topic on Modern.

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 ;
