Look at the blackening at the end of the tube. This is in the 12V fluorescent fitting which takes two T58W tubes. The supplied tubes are cheap Chinese crap

That is really cool to see such wear patterns on any tube, gives it a sort of a vintage or well used look to it Reminds of how I salvaged a PL fluoresant desk lamp that was used for the daughter of my mum's closest friend in Reading. I powered it up at home and the tube rectified and I tried using it for a few minutes until the flicker drove me nuts. I then took out the EOL PL tube and put a new 827 GE one in only to see it won't power up and looking back from what rectifying tubes do to ballasts is ruin them!!! Today I have not got the desk lamp with me

I will give LEDisease a taste of my shoe

I had a PL desk lamp one time and I miss it! I too love the wear patterns on tubes, like you said it gives that well used look to them. The electrode end here was slightly blue as it was sputtering a little, giving the tube that ripened look.

If this fixture operates these lamps at cold cathodes mode, even the best fluorescent lamps from Osram, Philips and GE, would sputter such. This fast end blackening here, don't related to the lamps being crap.

I"m don't speak English well, and rely on online translating to write in this site.
Please forgive me if my choice of my words looks like offensive, while that isn't my intention.

I only working with the European date format (dd.mm.yyyy).

I lives in Israel, which is a 230-240V, 50hz country.

Yep. I prefer decent triphosphor lamps over the crap ones supplied with the fixture anyway.
