It's not really daylight color isn't? To me it appears to be like 3900K or just a bit off cool white.

It's from 1937 and an incandescent lamp so of course it's not perfect daylight color. I don't know the exact color temperatur.

I get that but even the newer bulbs like this seem to emit the same color

Always lovely to see an old lamp lit, whatever the colour

I don't disapprove of LED's for domestic and other indoor use, I just don't like them for street lighting.

I was going to say a "Wedding made Lamp" , but then I saw it in the datasheet entry....1937...a historically significant time too.

The light doping of the glass with CoO is to correct the colour temperature upwards to around 4000K ....at the expense of efficacy of course. Remember, when this was made the fluorescent tube was still on a lab bench at Nela Park. However this pale blue glass technique was used right up into this millennium.

Manufactured articles should be made to be used, not made to be sold!
