I really like these tubes just for the sheer fact that they are so damn rare! For some reason Tungsram Warm Whites were very rare in Lithuania. In all of my previous schools, including my current tradeschool, had sheat-loads of tungsram Daylights and coolwhites in their basement lamp graveyards, but only one or two occasional rare pieces of warm white. In my current tradeschool they only had one case of 25 tubes that were Tungsram Warm Whites, all other ones were euther Cool Whites or Daylights. I don't know why that is. Probably because these tubes are horrible in a way that they produce the warm tone wia/ peach-orange hues, rather than in rich yellow-gold like modern Philips TL-Ds do. I don't like this peachy orange color, it makes everything look like it was lit by worn out oranged-out HPS. Nice tubes, but horrible peach tone. Nice additions to my collection!

LED-lighting is pseudoscience.
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.
