Northlight tubes, one is older than the other as it comes in a THORN sleeve, whereas the other is THORN EMI. also the date code dots are different.

Top tube is November 1982, bottom is May 1979. Sleeve and pins are a great help with dating the first lamp as Thorn used the identical etch in November 1977!

Tolerance respect and fairness = peace and harmony. The opposite also applies.
