LooK At MaRvElOuS ThAt PhOsPhOr CoAtInG!!!

I got two of these today, found them neatly set in a electronic waste bin in my local home improvement store. Both tubes has this horrible phosphor application going on, just pathetic. But it gives them authenticity. When in 1972 GE F40T12 tubes looked like modern ones in terms of quality, soviet tubes looked like they were made by a 200 pound gorilla and a stick so yeah. Both tubes were made in 1972, are USED but still working and LDC in color temperature witch means 5000k or daylight deluxe. Lovely tubes! Could outlast any modern tube you find today.

Actually, i was wrong, i had in mind the other two tubes. My mistake, these are used.

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 ;
