At that point, it is hard to see the filament on the smallest bulb

Pretty, please no more Chinese failure.

I remember these as a child. On a LCD watch you could push a button for "Light" and this would light up, showing the display. COOL!

Preheat Fluorescents forever!
I love diesel engines, rural/farm life and vintage lighting!

There are even smaller ones. Seiko used to make axial-lead vacuum lamps which were smaller than a grain of rice. They measured slightly under 1mm in diameter, and were assembled in a vacuum chamber with special automated machinery.

Thats really neat, I would love to get a bunch and see about retrofitting them into a digital clock to make it incandescent powered.

I had once a Casio wristwatch, which had a miniature incandescent lamp for backlighting. And I still have an old analog alarm clock with a miniature incandescent lamp.

I"m don't speak English well, and rely on online translating to write in this site.
Please forgive me if my choice of my words looks like offensive, while that isn't my intention.

I only working with the European date format (dd.mm.yyyy).

I lives in Israel, which is a 230V, 50hz country.
