1971 SLZ NOS F40T12 Daylight fluorescent tube

1971 SLZ NOS F40T12 Daylight fluorescent tube

Click to view full size image

Found four of these tubes in my collection, and I checked that I never presented these tubes, so I done it now. Nice long filaments, and the filament legs are extended for acting like anodes to spare the life of the filament. This tube was made in 1971 and is daylight NOS.

Is it just me but do the Soviet tubes seem to have more cathode glow than fluorescent tubes made elsewhere?

May all the great lighting technologies have their place in history.

No It seems this way because I always do these cathode shots while in preheat mode wia/ shorted starter The hotspot in soviet tubes forms the same way as in any other tube in the world.

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 ;

I just now realized that this tube is mislabeled.. well that's a first. LB means 35k or natural white, but the tube is actually daylight. Cool nonetheless
