Beautiful lamp.

I like my lamps thick, my ballasts heavy, and my fixtures tough.

Very nice lamp Dave, beautiful!

Linear fluorescent will never lose to LED!
I am not Anti-LED, as I have some in use at my house.

SWEET! I have a 20 watt Sylvania 4500 white on a fixture in my shop out back, also black bases, and like new. It seldom gets turned on, but I am thinking of fetching it to preserve it. Compared to a inside etch GE F20T12/CW, it is a bit bluer, and I have an old architectural magazine from 1946, that was apparently the year 4500 white was introduced, as it has a short article saying that! There is also a nice GE circline ad and some good fluorescent fixture ads including Smithcraft and Day-Brite. t was at the Edison in with some of my bulbs, so I took it home. It is in my museum trailer at the moment. Frankly, I wish they would bring back the 4500 white! It is nice---not as harsh as 4100-4150K CW, and not as snow white as 5000 white. They are really pleasant lamps, and I would light my shop with them if they were still available. Rick D.

Nice! I love oddball color temps like this between 4100K and 5000K.

To resist is to piss in the wind, anyone who does will end up smelling.

Looks like it has a lot of hours on it. Made one month before I was born!

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

You had the double cathode model! Two cathodes welded onto the leads.

I have a NOS Duro Test F30T8 4500 white. I used my cheating method ( heating of 1 cathode with 6 volts )on a RS fixture. Has GE style ends. Interesting lamp.

NNNN!
