Lampes CLAUDE à ballon fluorescent MBF (1956) « on: September 19, 2022, 04:23:09 PM » Author: Olav
Hello everyone,

I found a small price list from 1956.
The French company CLAUDE offered the MBF 80W, 125W, 250W and 400W lamps.
The 80W and 125W lamps have the usual outer bulb shape that was common in Europe up to the mid-1950s.



But I find the lamps with 250W and 400W striking.
It looks like the American BT forms BT-28 and BT-37.
I have not seen this before from a European brand.



Regards

I’m kinda surprised nobody has commented on this yet, but you post some really neat old advertisements. They give collectors a glance to see certain lighting products in their “heyday”.

Thanks for posting.

I wonder why the second page lists ballasts for both 220V and 120V mains. In case anyone is wondering, the mention SELF means a choke ballast (self-inductor) and of course AUTOTRANSFORMATEUR means, well, an autotransformer ballast.

Thank you for the comments.

@Econolite03:
you are welcome. It is difficult for me to write something about your statement.  The comments on "waste paper" are usually little or nulk.  That's my personal experience so far.  Brochures and catalogs about lamps and fixtures are no longer interesting for some people if they are not in English.  Catalogs are always interesting to compare.  Specifically to the content of this flyer: I assume that the MV lamps 250W and 400W were produced directly in the USA with E40 cap for sale in France (export USA to France).


@sol:
I'm not an expert on the old power systems in France.  However, I have found that in some regions there must have been different voltages in the power supply in the past: 110V or 220V.  That would explain the need for the different devices.

Hello Olav, Hello SOL,

Many thanks for sharing this brochures. Im not answering to everyone but I am enjoying reading them. It is notable that Claude was not the only french brand using the BT shape. The MAZDA MAF250W lamp was in a period of the 50s (proof in catalogue of 1654 and 1955) also BT shaped.
First I thought, it makes sense that claude has BT shaped mercury lamps, as I think that they worked together with Sylvania, which back then was mainly an american company and used these globes. However Mazda whom would be more affiliated to Philips also used it. And Philips certainly did not use the BT shape for its HPL lamps. So I might be running circles here.

SOL,
In France we had -especially in rural and mountain areas- until the 60s 110V grids from the early time of electrification.


Best regards,

Alex

@Olav and Alex : Thank you for the clarification. It does explain the availability of both types of ballasts.

France (and probably most other European countries) certainly did use different voltages in the past. The UK was no different, I have a list somewhere that shows the voltages in different parts of London in the early 20th century and it could have been anywhere between 100V and 240V, depending on location, also AC or DC..! More recently, I remember seeing 130V lamps on sale in France in the late 70's/early 80's (don't remember exactly, I was visiting quite often around then) so it must have been since then that the lower voltages were removed.

Hello sol,

today arrived a parcel from France with an autotransformer.



I didn't think I would ever find another one and in such good condition.
The connections for the 4 different voltages can be seen clearly.

That's a very nice ballast you've got there. Now, do the 210 and 230 terminals bypass the autotransformer and just use the choke part ?

@sol:
I haven't had time to check that with a meter yet.  I would be interested too.

@Alex:
MAZDA MV lamps from the mid-1950s have a slightly different shape.  The catalog shows a photo of a lamp MAF 250 and another catalog shows the lamps MAF 250 and MAF 400, but drawn (no photo).  It is very difficult to compare with the CLAUDE lamps of that period.  I have never seen the lamps from a collector before.
