Siemens Ediswan 5' 80W BC Deluxe Warm White

This is one of my proudest possessions. The print was already very faint when I first clapped eyes on it in the mid 70s. I didn't acquire it until the mid 90s. Now it's almost gone. From memory and very close inspection I think the text reads:
SIEMENS EDISWAN
FLUORESCENT
DELUXE WARM WHITE
80W
MADE IN ENGLAND
SILICONED
INSTANT START
2 27
The final line is an incomplete date code. Can anyone fill the missing links from the photos, which I have enhanced to the best of my ability?
