Philips Philora TL 100 - Alive!!

Philips Philora TL 100 - Alive!!

Click to view full size image

I am very proud to present my today's acquisition! A Philips Philora TL 100 fluorescent hot cathode tube! Probably the first Philips lamp of this kind. It seems actually in perfect fine condition and NOS, although it was hanging for over 70 years over an entrance of a building in the middle of a city, uncovered and unprotected!

I just let it burn on a 0.22A ballast which was tested before to work and not to be short circuited, as well only for two minutes. There's absolutely no end blackening. The tube just started to build up some condensed mercury on both ends. And now: Guess the color of this tube!

I got it today in the morning, and just before I cleaned it carefully to not wipe out anything.
The glass surface is rather uneven on the whole tube, not like modern fluorescent lamps. I am curious about the specified lifetime of this tube? And as well, it will have beryllium phosphor? What does the date code mean? I guess 1945, but the "V" in the middle is confusing...

Nice lamp! Is it 4100K, 4300K, 5000K, or 6500K?

Good quality things are awesome. Cheaply made things are not.

Amazing... Do you realize that this is very first modern picture of this lamp during operation? Thank you very much for showing it!

fluorescent lover 40 - The TL100 was available in two colors: daylight and warm-white (the standard white version was a brighter TL115 lamp). Looking at Marc's picture, I'd venture to say that this is a daylight version coated with mixture of zinc beryllium silicate and magnesium tungstate, so the CCT should be around 6000-6500 K (I have to check my literature in order to get the precise figure).

@rom1: It was an amazing show to see it light up after almost 75 years!!

And yes it‘s a daylight version. I didn‘t knew that there was as well a warm white version of the TL 100, and I am surprised that it is a daylight tube. Here, people prefer warmer light colors...

What about this TL115 you mentioned, Max?

it must be one of the few fluorescent tubes of this type still existing in the world !! I've never seen one so close !if one day you must not be able to keep it preciously safe, prepare a place before in a museum

OK, I have checked the technical specs of this lamp in a Philips book from 1942 (Gasontladingslampen, P.J. Oranje), and its color temperature is very close to 6000 K. Its electrical specs are: 105 V, 0.25 A, 22.5 W.


What about this TL115 you mentioned, Max?

The TL115 is essentially the same lamp with the same electrical specs, with a phosphor coating consisting of zinc beryllium silicate only. Because there is no extra blue or red emitter, the lamp's lumen efficacy is slightly higher (51 vs. 44 lm/W), resulting in a 115 Dlm output instead of 100 Dlm for the warm- and daylight-white versions.
