Absolutely beautiful!!! Never seen a Ken-Rad fluorescent lamp that old! Looks like it might even predate Ken-Rad's partnership with Westinghouse.

Way cool find. If it's from prior to 1946 which it very well could be, it's a true Ken-Rad.

Preheat and T-12 fluorescents forever! Down with LED's and instant start T-8 fluorescents.

its near eol but still works.looks almost like a warm white.but has a different look about it.must be the older berillym phosphors.the test fixture is a supposed 1939 desklamp which was totally trashed when i got it and was missing parts.it now looks new and has a 12v hf ballast which runs on my 12v solar system.are the older phosphors sensitive to being run on hf?
i noticed some tubes color is slightly different in these fixtures.some part of the blend has longer persistance.

It's phosphor is 3500K White, one of the original "whites" (the other was Daylight). It's color is between Warm White and Cool White.

I`m begining to wonder if this bulb is a 39 ???? I was under the empression that all late 1930`s fluorescents were side etchers ??? Maybe so maybe not , Also like how the glass diamiter is larger then the endcap itself.

Sure looks very early, never seen anything like that! Seems crude too.

My old early 1940s MAZDA daylight lamp came in a desk lamp (that is in beautiful condition) that a friend gave me years ago. I would absolutely NOT run this lamp on a HF 12 volt ballast. Those things trash lamps. Get you an everyday cheapie modern lamp for it and run this one with one of those "push, hold, release" fixtures. That will allow it to light and non violently rectify. It will last nearly forever that way.

actually the 12v ballasts are ok if you dont start it 100 times a day.these heat the cathodes so they wont sputter like those junky camping lights.
interesting discussion on the date.
had the industry developed to the point that all the majors bought parts such as bases from one mfr?
i need to pull all the antique tubes out and compare.

You can run a rectifying lamp for literally years on a manual preheat fixture. I have never seen or had a ballast like you are mentioning, but yes, those camping DC lanterns and the DC flashlight things absolutely destroy lamps.

i could not run a lamp that way.the strobing would be totally unaceptable!
this lamp just got added to the retired war veterans box.no point in running it except for demo.
i would hate to run any vintage lamps for other than a demo.
next up are 2 nos? sylvania 14w white with reddish brown caps.

got the antiques out for another comparison.this tube is identical in construction to the early westinghouse i have other than this one having a light knurl in the groove.also noticed on both that the glass on one end is ever so slightly larger.i also noticed the early ge is heavier.
