I actually found this tube in my collection. Turns out I had more 3ft tubes than I thought. I forgot about them probably because I never had a fixture for them. I remember I got this tube from recycling bin in some electrical store. The tube seems to be unused, but it has a broken cathode. Probably was hit hard and broke the cathode. But still lights up when shorted two pins, rectifies itself and lights up nicely.

I checked how much does an Osram F30T8 tube costs. Weird thing is that 30 watt and 15 watt t8 tubes are extremely expensive for no reason. Like, you can buy 5 F36T8 lumilux tubes for 10 euros. And one F30T8 or F15T8 tube for 10 euros. Why are they so god damn expensive???
