No, Dave, it is far more complicated than you think.
Philips has plants all over Poland...it is almost as if all their Dutch plants were transplanted there about two-three decades ago. Some plants can be eliminated easily however...the one in Kertzyn
just does luminaires, whilst Bielsko-Biala
just does bases/caps...this leaves Pabjanice
and TWO in Pila for lamps.
Here is the one I call "Big Pila"
....so big you would not think they would need any more land...but then there is "Small Pila"
to the south a few kilo-meteres.
NOW:- here is the problem we all face, (and I have been trying to get to the bottom of this FOR AGES) ...Which plant symbol corresponds to which site?
Sometimes Philips "move" their plant symbols...i.e. they closed a plant in Madrid, (which used the symbol of a lower open semi-circle with a vertical divider) and re-assigned this symbol to Fei-Xin in China.
Philips have three plant symbols for Polish plants, the two above, (of which the one on the left seems by far the most common in the last decade) and a third (which I have never seen on a lamp) which is simply the "infinity" symbol.
So they refer to the rectangle with the bottom missing as, "Pila-1" (Does/did CFL, CFLi, LFL, Mercury, Decor and Special GLS). The dot with backslash is called, "Pila 2" (and listed as doing Candles, Fancy Rounds [G45] and Reflectors) and the last one, the "infinity" symbol as "Pila 3" (and doing GLS, Miniatire Incandescent and Halogen).
Now, they may have moved these symbols, closed plants, mergered plants ...the one in Pabjanice I think once did T12s for Polamp but now it seems to be being tooled up for semiconductor....hence the "Lumileds" name on Google Maps....but take a look in Street View!
These companies also seem to have a somewhat flippent disregard for local culture and (geographical) detail too...and Philips Jakarta in Indonesia was nowhere NEAR Jakarta, but a few hundred kilo-meteres to the east in Sidorajo
, just south of Surabaya! The devil is always in the detail and if there is flippancy in the detail one will never locate the site! So any printed matter you see, you must not "take as wrote" but "read between the lines" and attempt to infer by what it NOT there rather than what is!
When I log lamps into my collection I WANT to so much put a place of origin, but one has to accept that sometimes there will be a source of error.
Reading between the lines I INFER that "Small Pila" is most likely their "Pila-2" doing candles and decor...and getting its empty bulbs from "Big Pila".
"Big Pila" is so big, it must do lost of things, glass, phosphors, cryogenics maybe....although Philips "farmed that out" to Air-Liquide ages ago. So it is likely that most of the lamps wee see now are from there.
There might be a THIRD PLANT IN Pila, I have to admit, I have not looked....if there were then Philips would "practically own the town!"
I always felt that the third "Pila" plant was actually Pabjanice, hundreds of kilo-meters at the south east near Lodz. BUT, I have no conclusive proof as to just which symbol it uses.
There are other things to consider here too.....Philips sometimes use the same symbol for DIFFERENT plants running at the same time but making different lamp types!
Thake these three plants in France:-
....GLS (No Longer Owned by Philips}
....T12 and T8 LFL.
(Again, it is advised that you look around using street view and select the oldest version of street view.)
All three used the same plant mark, an upper closed semi-circle, vertically divided....so the plant location depended upon both the plant mark AND LAMP TYPE!
So it is not as simple as it looks....they can "move the plant mark", as from Madrid to Fei-Xin, or use the same plant mark for numerous plants making different lamp types as in France...so in Poland this is the most likely reason why we are having difficulty determining the exact location of origin of the lamps in our collections....the place where the lamp was "tipped off", or the exhaust tube finally sealed...(least that is how I define it for lamps in my collection). I call it, "Nailing a Plant" ....and it is an important part of the providence of a lamp, but can be quite a challenge.
The trick is to "look wide"....seek to locate EVERY LAMP PLANT THAT EVER EXISTED and then try to see how they are all interrelated in a complex web of time and space....the more of the web you discover, the easier it becomes to discover more...like if a house has a "secret room"....if you know all the other rooms and their dimensions, the secret room becomes obvious as a wall twenty feet thick!
I hope to resolve this "Polish Philips Issue" one day, but for now all I can do is tell you what I have discovered and how I went about it.
If you look at the two lamps above, they are very similar in appearance and presumably function also...so that begs questions in itself ....
Was the plant mark moved?
Was the lamp type moved?
Where do the inner capsules come from, same plant or different?
I have LOADS of "Eco-Classics"
sold here in Australia...the nearest equivalent to the North American "Eco-Vantage" as far as I can tell. I always thought they came from Pabjanice...they have the mark of the bottomless rectangle as on the left above.
