Not only were they "Re-Branded" LU4000/D/40, but the design was so radically altered that practically no comparison can be made apart from the fact they came from much the same geographical location. I even think the bulb molds were altered.

Do you have the clear TCF 400/250/150 Colin?
So you can see the absolutely unique seal design this lamp has. (Upper right hand image is TCF 150, lower Left is GEC HPS/U 400.)

Manufactured articles should be made to be used, not made to be sold!

In my opinion, you mistake. This lamp is the beginning of the 90s. For an exact understanding of the need to see the base.

I have quite a few of these, our electricity authority swiched to them as a cheaper alternative. If I look back into my database I should be able to see the range of dates I collected them between.

Gospodin, is the date code on the base somewhere?

The earliest record is September 1988 for a TCF 400, the last one I picked up was in June 1992.
So my collecting period spans the time when the Vaci Way plant was taken over by G.E.

Once G.E. took over the plant, they changed all the machinery on the production line for high pressure sodium, even the bulb molds were changed. Although these Tungsram lamps with their unique design were quite high quality, G.E. must have had their reasons to radically alter the design. The amalgam resevoir being one of them.

After the G.E. takeover the design became much more "Western European" and the lamps looked superficially more like Philips' SON/SONT or Sylvania's SHP/SHPT series. There were also elements of the original North American LU (Lucalox) series, particularly internally.

What is interesting to note, is the TCF 400 had a "cigar" shaped bulb, I think it is actually designated "ED-18" in Imperial eights of an inch, ED-56 in metric...and the original Lucalox's also had much the same bulb shape, whereas the LU series made at Vaci Way had the more usual "T" type bulb, T-48 I think it is in metric.

In the 1980's, they used an old box for lamps with red and blue designs. This design is new. Also can to see the box from the butt, it's cover.
There is no date code on the base, but the base also changed over time. I have lamps of the 80's. I also have a lamp TCL400 of the early 90's. If i can compare the base, it will be exactly clear. I see code 2A or 3A. Hard to see. For this reason, i think that this is January 1992 or 1993.

I know what you are getting at....this has a "Conform-Fit" base, i.e. it is screwed on over a molded thread in the bulb and then locked in place with a blob of lead on a dimple in the neck. The older base you mention, probably has a thread free area right at the rim and held on with heat-cured composite cement/glue.

The G.E.C. series of "Solarcolour" High pressure sodiums underwent this same change in about 1978.

Yes, Gospodin, exactly...the one on the right is a "Cemented" base, on the left, "Conform-Fit" I will try to find examples here on L.G. from my own posts...


1976 G.E.C. "Solarcolour" HPS/U 400 with older cemented base....note the flat bottom and thread-free rim like your drawing on the right.

Two G.E.C. MBFR/U 1000's from the same plant as the HPS/U, but ten years younger, (1986) with the conform-fit bases like your drawing on the left.

There is a third base type (E39/40) and that is the "Crimp Shell" base...it is a U.S. invention, so most often seen on their lamps. It involves molding three or four "dimples" into the glass of the lamp, then a sub-base with a small amount of thread three or four springy dimpled fingers is snapped onto the lamp then the base proper is screwed on over that and holes punched through both the outer (proper) base and the inner (shell) sub-base....the burrs at the edge of the holes lock the two together and stop the outer (proper) base from unscrewing.

I'll see if I can find an example... Yes, here, on the lamp on the right.

I found my picture of the disassembled seal of this series of lamps.
