Today after I finished my greenhouse upgrade, I sat down and looked at adverts on internet about lamps. I found one local in my area, and the dude was selling a full box of these! HOW A W E S O M E IS THIS! In soviet union F30 T12 tubes were incredibly rare! There were plenty of F30T8 but T12??? That is practically unheard of! Even in Russia tube collectors struggle to find these tubes in their area, and here it is - a DUDE in Lithuania that HAS A FULL BOX OF THESE! This picture shows the tubes lit. It is 30 watts, T12 and LB color (Natural white) at 3500k. Being unused NOS, sitting in a unheated shed for 64 years it did struggle to start, but all of them did start, except for one. One had air leaked inside and it the filaments pinged on me after few blinks from the starter. Shame, but hey - at least I have four absolutely beautiful and extremely rare brilliant examples of soviet industrialization. These tubes had so little demand in USSR that these were made probably once in 5 years in a small batch and then equally distributed trough the whole of USSR. The reason why they had so little demand was that the 60% of all illumination in soviet union was done by 4 ft F40T12 and 5 ft F80T12 HO fluorescent tubes. The other 35 to 38% was done by F20T12 and F30T8 and other short equivalents and the rest 2 percent were F30T12. So you can see that me finding these things unused in original sleeves is one of the chances that never happens twice. I might go and buy myself a lottery ticket I don't know.. .

My idol is Mylene Farmer, deal with it.
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.
