Title: How to find Sainsburys 100w Mushroom bulb date of manufacture?
Post by: ethanol on June 03, 2023, 04:12:33 PM

Hi, would anyone happen to know when these mushroom bulbs were made? Had a look at some very old sainsbury scatalogues and found some that were from 1983. Would be rather interesting to know the actual date of them.

Hello,
The 0192 next to the barcode on the box may imply that the box was printed or designed  in january 1992 . Tat would also line up with my approximately date estimation.

The lamps itself has a 4D marking. Applying the Philips code that would bring us April 1994.
Best regards,

Alex
