Cool find! These soft pink bulbs cast such pretty and relaxing light.

The J2 means it’s made in September 2002. The upside down bracket means this bulb was made in Poland.

I can’t find these anymore and my last one broke because I accidentally dropped it and the filament popped

2002 sounds about right for this as it has the vintage chalk drawing packaging graphics along with a peep slit

A nice find! These are much harder to find now sadly. I have a box of two of these as well and I would concur the date of 2002 as almost all Philips lamps of this era have that style etch. I've got some Crompton and Leuci versions of these pink ones too; the Leuci ones being 25W. Really nice bulbs!
