Indeed a very nice tube, from this era I wonder what kind of phosphor it employs. Maybe still one of the originals with silicate phosphor.

Dave, I am impressed you know this old code! Wouldn't it be Mazda branded if it was from '45?

I have a similar tube Mazda F14T12 White. It has a bar under the first A and above the second A of MAZDA. Could you date that also? I was guessing early 40's from the kind of phosphor it uses.

James, I got your email last week or so, I will reply within 1-2 days. That's the same Mazda lamp as on your website? I will take a look. I have two Mazda GE T12s and a bunch of GE and Westinghouse Mazda T8s. Even a couple GE Mazda T5s.

Yes this lamp contains zinc beryllium silicate phopshors, but being a Daylight it has less beryllium than the 3500K White.

iirc the mazda name was dropped in 1945.
anyone know when the old style phosphor was dropped?this one has the same spectrum about it as my very early f15t8.

In the USA beryllium was dropped in June '49. The Mazda brand was used until '44-'45 incandescents and some fluorescents still had the Mazda name in '45.
