HomeBase TCP F20T12 827 & 840 Fluorescent Tubes

Ever since the very start of this trade with Daniel and Jonathan I was really interested to have a couple of these tubes, at the very least in color 827, because com'on a T12 tube in 827??? HOW AWESOME IS THAT??? I am very thankful that Daniel gave me these tubes. Although they are quite rubbish to be honest, because they flicker quite a lot due to the krypton filling, and kind of hurt the eyes, but on my trusty Osram quictronic ballast they work smoothly and the color is really nice. The cathodes are really tiny and kind of crappy so I suspect these wouldn't last very long on long hours. Are these tubes still available for purchase in GB? I also must say that these generic chinese T12 endcaps are very... unattractive IMO.
